Dogs’ Brains

Many surprises and, probably, more to come!

Among the many dog-related blogs that I read is Treehugger. It covers a wide range of sustainable actions and habits and not infrequently writes about dogs. That is the main reason I follow the blog.

On January 12th, 2022 the blog site carried an article about the ways that dogs hear speech. It was called Dogs Brains Can Distinguish Between Different Human Languages.

I republish it below:

Dog Brains Can Distinguish Between Different Human Languages

They also can tell the difference between real speech and scrambled speech.

By Mary Jo DiLonardo

You talk to your dog, and of course, you’re convinced your pup understands you. But what if a dog is plopped down in a place where suddenly everyone is speaking a different language?

In a new study, researchers have used brain imaging techniques to find that dogs can differentiate between familiar and unfamiliar languages. Researchers say the findings, from the Department of Ethology at Eötvös Loránd University in Hungary, are the first evidence that shows a non-human brain can distinguish between languages.1

A few years ago, first author Laura V. Cuaya moved from Mexico to Hungary for her postdoctoral research. Before the move, Cuaya’s border collie Kun-kun had only heard Spanish. She was curious whether he would notice that people in Budapest spoke a different language, Hungarian.2

“Like many dogs, Kun-kun tends to pay attention to humans, trying to predict their social environment,” Cuaya tells Treehugger.

“When we moved to Hungary, it was a whole new world for everyone. In Budapest, people are very friendly with dogs. When people talked to Kun-kun, I wondered if he picked up the language difference. And happily, this question fitted with the goals of the Neuroethology of Communication Lab.”

For their study, researchers recruited Kun-kun and 17 other dogs, who had been previously trained to lie still in a brain scanner for functional magnetic resonance imaging (fMRI).1

The dogs were played speech excerpts from “The Little Prince” in Spanish and Hungarian. Each of the dogs had heard only one of the two languages: Hungarian was the familiar language of 16 dogs, Spanish of the other two dogs. That allowed them to compare a very familiar language with a completely unfamiliar one.1

Researchers also played scrambled versions of the excerpts to the dogs. These were nonsensical and completely unnatural. This was to test whether they could tell the difference between speech and nonspeech.1

They compared the brain responses to the two different languages and to speech and nonspeech.

“We found distinct cerebral regions for both processes: for speech detection (speech vs. non-speech), the primary auditory cortex, and for language recognition (familiar language vs. unfamiliar language), the secondary auditory cortex,” Cuaya says.

“Our results may suggest a hierarchy processing in the dog’s brain to process speech. In the first stage, their brain would detect whether a sound is speech or not. Then, in the second stage, their brain would identify whether the speech is a familiar language or not.”

The results were published in the journal NeuroImage.

Exposure and Age 

Researchers found that no matter which language the dogs were listening to, the primary auditory cortex of the dogs’ brains could distinguish between speech and scrambled, nonspeech.1

“Dog brains, like human brains, can distinguish between speech and nonspeech. But the mechanism underlying this speech detection ability may be different from speech sensitivity in humans: whereas human brains are specially tuned to speech, dog brains may simply detect the naturalness of the sound,” says Raúl Hernández-Pérez, coauthor of the study.

They also determined that dog brains could differentiate between Spanish and Hungarian. Those patterns were found in a different region of the brain called the secondary auditory cortex.1

Researchers found that the older the dog was, the better their brain was able to tell the difference between a familiar and unfamiliar language. That suggests that the longer dogs live with their people and are exposed to a language, the more they understand how their language sounds.1

“As we could not control the amount of exposure to language in our study, we used the dog age as an indirect measure of the time dogs have been exposed to a given language,” Cuaya says. “I hypothesize that dogs with a closer relationship with humans will better distinguish languages. It could be great if future studies test puppies to control the exposure to a language better.”

Dogs as Models 

Researchers are curious whether this language differentiation is unique to dogs or whether other non-human animals may also be able to distinguish between languages.2

“A variety of auditory regularities characterizes each language. For example, sometimes, we cannot identify what language we are listening to. However, we can likely recognize its general origin (e.g., an Asian or Romance language) because of its auditory regularities,” Cuaya explains.

“Detecting regularities is something that brains do very well, not only humans or dogs’ brains. It is highly likely that other species can be trained to differentiate between languages successfully.”

But Cuaya points out that in their study, dogs weren’t “trained.”

“Their brains detected the difference spontaneously, perhaps due to the domestication process,” she says. “While it is likely that other species can differentiate between complex sounds, it is possible that just a few species are interested in the human language.”

Researchers believe the findings are important because by studying dogs, they can have a broader picture of the evolution of speech perception.2

“Dogs are an excellent model because they have been living—and cooperating—with humans for thousands of years. When we wonder if another species cares about what humans do, it is inevitable to think of dogs. In the case of language perception, we can learn, for example, that different brains—with different evolutive paths—can carry out a similar process,” Cuaya says.

“Also, as someone with dogs in my family, it is lovely to know that dogs are picking up subtle cues of their social environment all the time.”

Time after time I learn new things about dogs. This is another example of the mystery of a dog’s brain. Thank goodness there is scientific study into our lovely animals.

A sailing memory, part two.

Again, this is for Pendantry.

I left yesterday’s post with the statement: “However, getting to Gibraltar was not without its challenge for we suffered a knockdown and this scared us both to the core.”

This is the account of that knockdown.

ooOOoo

The knockdown

So this was it, the end of life. This is what that end felt like. A lifetime of experiences reduced to this stilled moment; all my hopes, dreams, pleasures, memories, everything shrunk to this tiny moment of now.

I knew, in some trance-like way, that if just one of those foaming, giant waves swept across us, so utterly over-whelmed as we were on our side, it would flood the cabin, and down Dave and I and the yacht would go.

Other sensations came to me. Feelings of quiet, of calm, even of peace. My world now reduced to close, intimate dimensions. To the yacht’s wheel, to which I so grimly hung. To the front edge of the port cockpit seat, now underneath me, against which I braced my feet. To the starboard guardrail, bizarrely above my head, and to those raging seas so very close that seemed to beckon, ‘Give up, give up now and slip away.’

Me and Dave, alone in this Mediterranean storm 10 days West of Cyprus, are going to drown, founder without trace in these vast waves and probably end up not being missed for many days. Our dream of sailing across the Atlantic snuffed out as easily as Songbird of Kent would sink the 5,000 feet down to the seabed. The futility of it all.

It was a strange, detached perspective that hardly registered the gusts coming at us like great padded hammers. This unimaginable gale that had Songbird of Kent, my floating home for the last 5 years, totally pressed down on her port side, even though the yacht offered nothing more to the winds than her bare mast and rigging.

From within the cabin, Dave could do no more than simply watch. Hunkered down outside, I could do no more than simply hang-on. Both of us transfixed in this stillness of life’s imminent ending. Dave would later say no words would ever properly describe what his eyes had seen.

My past life, rather ominously, started running before me. How one year, in the early 1950s, when I was 7 or 8 years old, my parents had rented a holiday villa in the French Atlantic coastal town of Arcachon. What a glorious summer holiday that had been.

Arcachon’s beautifully sheltered bay had enabled me to learn to swim. The buoyant sea-water helping me increase the number of strokes each day, until one afternoon I had swum out to a yacht anchored well off the beach. As I hung on to the anchor chain, panting hard, the owner looked over the guardrail. Next, me being rowed back to the beach in a dinghy and then everyone getting to know Englishman John Calvert, a solo sailor living aboard his yacht, Garrawog.

Next year we had holidayed again in Arcachon and found Garrawog moored in the small yacht harbour. I recalled fond memories of sitting in the cabin with my father and John Calvert, drinking lemonade, eating cream crackers and loving the cosiness of it all.

Then the amazing coincidence when the following year we had holidayed at the French Mediterranean town of Menton and Garrawog had sailed into the harbour. That had led to John taking us sailing along the coast, memories so vivid, all these years later, of helping to haul sails, steer Garrawog, even remembering the gentle nudge of the yacht into the waves.

I was clear how those memories had fuelled my romantic obsession with sailing. How as a young teenager growing up in London I had joined the Welsh Harp sailing club, based at a large lake, well a reservoir, just three miles from home, and learnt to sail a dinghy. All fuelling this fascination with the sea. Yet that romantic obsession didn’t revolve around idyllic meanderings along the Mediterranean coastline. No, my dreams involved ocean sailing. Not even as part of a crew, but sailing, single-handed, across the oceans.

I had devoured every book written by those sailors who, totally alone, had journeyed the vast oceans in a small yacht. Joshua Slocum, who wrote of his solo trip around the world in his yacht, Spray, way back in 1895. Master English navigator, Francis Chichester, who conceived the idea of a single-handed yacht race across the Atlantic ocean, later completing a round-the-world solo circumnavigation in his yacht, Gipsy Moth IV. Eric Tabarly, Chay Blyth, Robin Knox-Johnston and many more.

I reflected how that dream had remained with me for years. All through nearly 20 years as a salesman and entrepreneur to the point when, quite suddenly, on a Monday in the Spring of 1986, uncharacteristically I had nothing in my diary for that day, or for many days ahead. I had just sold my thriving company in Colchester and there was no longer a job to go to!

Then not so long after I had taken a holiday in Larnaca and in wandering around the marina I had seen Songbird of Kent for sale, and had bought it! I had previously read about Tradewind yachts and knew how many had made world circumnavigations. Thus by the end of 1986, my new address had become: Yacht ‘Songbird of Kent’, Larnaca Marina, Cyprus.

A shout from Dave jerked me back to the real world.

“Hey, is it my imagination or is that wind easing?”

I lifted my head and turned my face into the weather coming full at us. The seas were just as terrible but, yes, something was different, some subtle lowering of the tone of the wind.

“Dave, you’re right, it has eased back a bit. We’re not so pressed down, are we?”

“Don’t think so. What do you reckon?”

“Not sure what to do, frankly these conditions scare the shit out of me!”

In the subtlest way imaginable, Songbird provided the answer. The yacht now showed some response to the waves rather than previously being so overwhelmed. A tiny thought entered my mind, something I hardly dared acknowledge: Songbird is not going to founder.

Those 3 tons of lead at the bottom of Songbird’s keel were, at last, overcoming the wind pressure on her topsides and with seawater cascading down from the mast and rigging, the yacht slowly righted and bestowed on me and Dave the continuation of our lives. A miracle of miracles!

I quickly helmed the bow round to point us downwind, putting the full force of the gale directly aft. Within moments, a wave slowly started to overtake us but I couldn’t do anything other than keep my eyes on the mast-head wind-vane that, against all odds, had stayed intact during the knock-down. Watching the arrow head that absolutely had to keep pointing directly into the wind. We may be upright but one slip of steering, one moment’s loss of concentration and I knew we would slew broadsides to the seas and go over again.

I couldn’t believe the size of this wave that lifted us up and up, as if we were in giant, invisible hands. Up to the foaming crest from which was revealed, all around us, wild, angry, jagged waves, huge crests covered in white foam, an Alpine-like scene of raging hell as far as the eye can see. A vista of utter desolation.

Then the foaming crest moved ahead of us and Songbird slid down that vast lee of the wave, down towards the trough that lay behind us. Our bowsprit pointed directly into the dark green water ahead, water streaked with spume, as down and down we went until the inevitable arrival of the next wave started us up to another foaming crest.

We had survived what we could never have imagined. Hardly believing it, we intuitively knew that surviving that first wave increased the odds of us surviving the next few. Then the next few, and the next few until, against all expectations, we knew we stood a chance of living through it all.

I spotted something in the water and shouted, “Dave, look, look there in the water, just to our left. That bit of sail, surely not from our mainsail?”

As we ran before the weather, a scrap of white sail had surged past our side, a piece of sail bearing the number 33 and two palm trees, the symbol of a Tradewind 33 yacht.

Dave laughed, “I can’t believe that, Paul. It’s from the mainsail that blew out when the gale first struck. How amazing! It must be from us, can’t be too many other Tradewind 33s out here!“.

“Imagine that, Dave, after all that we have been through these past few hours, we’ve just sailed by a bit of our mainsail, close enough to have grabbed it.”

That triggered my mind as to when this terrible experience started. How long ago was that? I didn’t have a clue, though surely it couldn’t have been much more than an hour or so ago. Indeed, I struggled to think what day it was, then realised it was Thursday, October 8th, 1992. Just 24 hours since we had left the dirty, commercial port of Algiers for the last leg of our trip from Larnaca in Cyprus to Gibraltar.

“Dave, hand me the log, it’s at the back of the chart table.”

I read,

Thursday, 8th October, 1992.

08:20 Sea state terrible.

I recalled how the dawn had revealed banks of low angry clouds, skidding across the tops of a nasty swell, made even worse by a vicious cross-swell. The next entry after that read,

09:00 Sky extremely threatening. Wind NE F4. Just 16 miles east of Greenwich meridian.

Then we had approximately 3 hours of sailing to go before we crossed Greenwich. On to the last entry,

12:00 Sea extremely ugly, Wind NNE F5. Longitude 2 minutes East of Greenwich.

Just 15 minutes from crossing that historical navigational line. I recalled how we had chatted about sharing a glass of something to celebrate ‘crossing the line’! Then how my words had been torn away when, in a seeming instant of time, this huge squall had come out of the North, heralding this vast, cauldron of a storm. The mainsail, even tripled-reefed, was way too much sail. But it was far too dangerous to leave the cockpit to drop the sail, too much to do anything other than hang on.

The mainsail failed, ripped into shreds as it tore away from the mast-track and disappeared into the storm. The sounds of the event obliterated by the screaming noise of a wind that I had guessed was now more than 50 knots. The rain and spray had stung my face so hard that I needed to turn my head away just to breathe. Clearly something had to give; I expected the mast to fail.

But it didn’t! Instead, as the wind force grew and grew, it steadily pressed us further and further over until Songbird ended up fully horizontal to the sea. It seemed a lifetime ago.

I looked at my watch: 5.30pm. To hell and back in so few hours!

“Dave, what’s our position?”

Dave ducked out of sight to read the GPS, came back out with a slip of paper on which he had written our position: Eight minutes of longitude west of the Greenwich meridian. We were now in the Western hemisphere!

“Come on, Dave, you take the wheel. I’m going to fetch a couple of beers.”

“I reckon a double celebration, Paul, crossing the Meridian and living to tell the tale!”

We drank our beers, chit-chatted about nothing much, both aware that we had literally stared into the abyss of a dark watery grave, and sailed on.

Just before 13:00 on Saturday, October 10th, Songbird rounded Gibraltar’s breakwater, briefly rolled in the cross-swell, and slipped into the calm waters of the inner harbour.

Soon we were safe and secure in a marina berth, a few minutes walk from good food and friendly bars. Our experiences rapidly migrated into the private worlds of our minds, as if discussing it openly might replay it all with a different, more tragic, outcome.

I struggled through those first nights of sleep. Again and again I awoke, panic across my chest, clinging to the sides of my bunk, trying to lay all the nightmares to rest. Slowly, those October days resting up in Gibraltar shone a light on this sailing obsession. How, with the sudden death of my father in 1956, those memories of idyllic times in and around Garrawog had buried themselves deep into my hidden emotional world. How dreams of sailing had more to do with keeping the memory of my father alive than with anything else.

That gale expunged the obsession. I never sailed on Songbird again or, for that matter, on any other sailing vessel. Paid crew eventually returned Songbird to England, where she was subsequently sold.

I would never forget the stillness I had experienced in the midst of all that chaos, but one knock-down in a lifetime was more than enough.

ooOOoo

This is absolutely a true account of what happened. Yes, an intimate, personal account of what happened but accurate down to the last detail.

I am so pleased I kept a written account of the knockdown all those years ago for if I was to recall it today then much of the detail would have been lost. Maybe lost as a result of old age or lost as a consequence of not wanting it in one’s mind. Who knows.

Finally, there are no photographs because we just had more important things to look after – keeping ourselves alive!

A sailing memory, part one.

This is for Pendantry!

There was a remark left on my post on Tuesday by Pendantry. This is what he said, “Still waiting to hear the story of that dangerous trip you took (once?) that you dropped a teaser about years ago….”

Well not only am I including the excerpt from the book Letter to a Grandson, as yet unpublished, but I am extending it to two posts, simply because I think it’s too long for one.

So this is part one.

Tradewind 33 – Songbird of Kent. My home for five years.

 

ooOOoo

Songbird Of Kent

I decided to sell Dataview and worry about the taxation later. Now it is easy to write that all these years later knowing how it turned out; I never paid the tax!
For that same year, 1986, I went to Cyprus on holiday. Or rather I should say I went to the Greek half of Cyprus, to Larnaca, for a well-deserved holiday.

In wandering around the marina one day I saw a boat for sale. It was a Tradewind 33, a heavy-displacement cutter, called Songbird of Kent. The owners, Michael and Betty Hughes, were selling after many years of living on board and they returning to their native Wales. It had been extensively cruised in the Mediterranean with the base being Larnaca Marina.

 

It was a lovely boat and I could afford it. Plus, it offered an answer to my prayers. If I bought Songbird of Kent and left the UK before April 15th 1987 and stayed away for four tax years there would be no tax to pay. Nothing; Nada!
So that’s exactly what I did!

 

I bought Songbird, flew back to Devon and made preparations for leaving the United Kingdom for good. It was a busy period. One that had me saying cheerio to my son and daughter, but insisting that, so long as they came out to see me, it would not be four or five years before I saw them again. Plus loads of packing up, disposing of my house and eventually boarding that aircraft with a one-way ticket: London Stansted to Larnaca, Cyprus.

 

I settled in to living on board Songbird of Kent. I bought myself a small motorbike and in time, believe it or not, discovered there was a gliding club on the Island, at Kingsfield just to the East of Larnaca. The airfield was built for the Army Air Corps, possibly around 1960, but I can’t remember whether or not it was still in military hands. I don’t think it was!

But, I am able to look up my flying log and see that I flew a T21 from Kingsfield on the 28th October, 1990. It became a regular habit; quite quickly, as on the 17th November, 1990, I completed my instructor flight test and was signed off to instruct.
I also took an Advanced Open Water Diver course run by instructor Ian Murray. Ian was a PADI diving instructor. PADI stood for Professional Association of Diving Instructors.

My life was pretty good.

 

Each summer I would sail solo to Turkey, usually West along the South coast, the Greek side of Cyprus, then turn North and make it to Alanya or Antalya. There I would wait for guests to come from England including, most importantly, for Maija and Alex to visit.
Then we would gently cruise from harbour to harbour westwards, sometimes entering Greece much further West.

One day in Larnaca Marina a boat came quietly in and moored in the vacant berth next to me. I hopped off Songbird and went to help the sailor on board. It looked as though he was sailing solo.
After he had been securely moored, I asked him where he had come from. He was English; his name was Les Powells. He unassumingly said he was on his way home after a solo circumnavigation. Indeed, I later learned that it was his third solo circumnavigation!

The mind absolutely boggles! I mean I have just an idea, from reading books written by Francis Chichester and others, what a single solo circumnavigation would be like. But three!!
Over the coming days, we chatted about a whole range of stuff. When the subject of glider flying came up, Les said that was something he had always wanted to do.

I immediately offered to teach him to fly gliders. For a few weeks thereafter, we drove across to Kingsfield, when the Club was operating, and I taught Les up to the point where he went solo.
In the time we spent together, Les inspired me to undertake more longer sailing trips than just going across at the start of the season from Cyprus to Turkey and, of course, returning at the end of the season. Maybe, even try a transatlantic.

The idea of crossing the Atlantic kept nudging away at me. Especially since Dave Lisson, a Canadian friend from Larnaca Marina, was very much in favour of coming with me. Dave and I chatted about it and we agreed; we would give it a go! It was 1992 and a little late in the year to be starting off but we reckoned on it being alright. We left Larnaca Marina on the 10th September, 1992.

 

The idea was to head for Malta bypassing Crete. The weather soon became less than idyllic and by late on 13th September I made an entry in the sailing log: Conditions deteriorating. Then a further entry in the log at 11:00 on the 14th: Giant seas 3-4 metres.

Eventually on the 20th September we entered Valletta Harbour. We set off again on the 24th September. Our next port of call was Sidi Bou Said marina in Tunisia, which we entered on the 26th September.

The plan was to sail directly from Sidi Bou Said to Gibraltar but, once again, the weather got in the way. Thus on the 3rd October we entered Algiers harbour to take on fuel and to have a rest from the inclement conditions. We left Algiers on the 7th October heading for Gibraltar.

 

I must say that sailing in a smallish yacht had an almost unreal quality to it. The routine of sailing soon enveloped us. We slept frequently but lightly. At night, every twenty minutes or so, the one on watch would come on deck to take a look round. There was a simplicity in sailing, using a self-steering gear to helm the boat, and I remember one night coming on deck, there wasn’t a moon, and all around me, literally 360 degrees of vision, the stars came right down to the horizon. I was transfixed. We were far enough from land not to have any light pollution. It was magical. Indeed, it was a memory that has never left me.

 

However, getting to Gibraltar was not without its challenge for we suffered a knockdown and this scared us both to the core.

Our modern connected world!

A delightful conversation with Amit Roy.

Way back in 1978 I started a company called Dataview. It was based in Colchester, Essex and I sold Commodore Computers; the ‘PET”, standing for Personal Electronic Transactor.

A photograph of a very early PET.

Now I was a word-processing salesman for IBM previously and didn’t know a thing about computers. I operated out of a small shop at first in Church Street and people came into the shop and played around with my demonstration models. Unbelievably I sold some!

Later I got involved with a software program known as Wordcraft. The first comprehensive word processing program for the PET. Indeed, I had the exclusive world distribution rights to Wordcraft. One thing lead to another and soon I was operating from much larger premises down at Portreeves House at East Bay, still in Colchester.

I appointed a Head of Marketing, Amit Roy, and the company grew and grew. I focused on appointing distributors across the world, and that included Dan Gomez in southern California, and he became a close friend being my best man when Jeannie and I were married in 2010.

Anyway, back to the story of Dataview. Eventually I sold out and escaped the country (and taxes) by moving to a yacht in the Greek side of Cyprus before April 15th. I went to Larnaca Marina. That was in 1986.

On Sunday, through a link from a mutual friend, I called Amit, the first time we had spoken since 1986. We had the most delightful of telephone conversations.

Amit was born in Burma, he is now 79, and lost his wife some 13 years ago. The counsellor who saw Amit after the death of his very dear wife said that he had to be strong and to take up something he could become passionate about. Amit joined the Colchester Photographic Society and took up studying again, in photography, and became a very good photographer.

With Amit’s permission I share some of his photographs with you.

Chasing Waterfalls

Posted on

Written by I recently returned from a research sail through the Denmark Straits and I couldn’t be more in awe of mother nature.

We sailed aboard the gaft-rigged ketch Tecla out of Isafjordur, Iceland, bound for Greenland. We were thirteen women and men on a hundred-foot steel-hulled sailing vessel.

As we cleared the steep-sided fjord and sailed out into the bay past towering headlands, we saw a humpback whale breach. It rose straight out of the water, extended enormous knobby flippers, rotated and fell on its side with a large splash.

We sailed on, and another wheeled before us.

Further out, white-beaked dolphins streaked, exhaled, and splashed in the bow waves at the front of our boat.

Gray and white fulmars with outstretched wings carved the sky and nearly scratched the sea. And then there were icebergs.

The natural beauty of Mother Earth never ceases to take my breath away, no matter how many times I see it.

We traversed the threshold between the Atlantic and the Arctic Oceans. The south-bound East Greenland current squeezed between the craggy coasts of Iceland and Greenland to become a “superhighway” for turbulent water. Here, the denser Arctic water mass crashes into the bulwark front of warmer Atlantic Water. Arctic water plunges downwards into the Denmark Strait Cataract. This is the world’s largest waterfall. Yet, skimming the surface of immense water all we see are waves that crest white tumble and stream like the tossed manes of charging horses.

Unfortunately, we also saw the threats to nature.

First, a quick science lesson: When seawater freezes at the ocean surface, the ice is actually made of freshwater; the salt gets rejected back into the surrounding water. That surrounding water then becomes denser and sinks. This happens on a massive scale, which results in ocean currents around the world. Think of it like an organic engine that circulates the oceans’ water.

Now, because global warming exposes more of the surface every summer than it used to (about twice as much, in fact) that means more surface ice each winter. That means that our ocean circulation engine is twice as big, which radically alters the seascape, threatens not only the ocean ecosystem – from tiny algae to those humpback whales – but life worldwide.

We caused global warming. Now we must come together to decrease carbon emissions and increase carbon capture. For the Denmark Strait, for the humpback whales, and for our own places of habitation.

ooOOoo

I will do no better than to repeat that last paragraph.

We caused global warming. Now we must come together to decrease carbon emissions and increase carbon capture. For the Denmark Strait, for the humpback whales, and for our own places of habitation.

Here! Here!

The moon

A poem

The Atlantic was smooth under the night sky,

It made a very welcome difference.

Nights were hard on this solo sailor,

A quick scan of the horizon every twenty or thirty minutes and then back down to my bunk.

 

But what was that!

For the first time in ages there was a strange light off the starboard bow.

Impossible to gauge the distance.

Then I had it!

It was no ship’s light,

It was the edge of the rising moon.

 

My bunk below was forgotten in an instant.

The sight of the rising full moon was everything.

It rose seemingly rapidly and now cast its light over the ocean.

My ketch sailed in its golden light.

We seemed to sail on forever.

 

Now that’s coming on for thirty years ago,

But it is still clear in my mind.

Clear as if it was yesterday,

Reminded of it each full moon.

My ketch still sailing in its golden light.

The following is not Songbird but a much more appropriate photograph.

And the poem came to me just the other day. The memory of that full moon out in the Atlantic en-route to Plymouth from Gibraltar in 1991 will be with me for ever.

The Morse Code is 175 years old!

Two days of nostalgia follow! (You have been warned!)

As many of you already know, my father died fairly suddenly on December 20th, 1956. I had turned 12 some six weeks previously.

After about a year my mother remarried. His name was Richard Mills. Richard came to live at the house in Toley Avenue and had the unenviable task of taking on a new ‘son’ and ‘daughter’. (My sister, Elizabeth, some four years younger than I.)

Richard was a technical author in the newly-arrived electronics industry and one day he asked me if I would like to build a short-wave receiver. He coached me in the strange art of soldering wires and radio valves and other components and in the end I had a working receiver. That led, in turn, to me studying for an amateur radio licence. More of that tomorrow.

But the point of the introduction is to relay that The Morse Code is 175 years old on the 24th May.

Simply elegant, Morse code marks 175 years and counting

The elegantly simple code works whether flashing a spotlight or blinking your eyes—or even tapping on a smartphone touchscreen

There’s still plenty of reason to know how to use this Morse telegraph key. (Jason Salmon/Shutterstock.com)

The first message sent by Morse code’s dots and dashes across a long distance traveled from Washington, D.C., to Baltimore on Friday, May 24, 1844 – 175 years ago. It signaled the first time in human history that complex thoughts could be communicated at long distances almost instantaneously. Until then, people had to have face-to-face conversations; send coded messages through drums, smoke signals and semaphore systems; or read printed words.

Thanks to Samuel F.B. Morse, communication changed rapidly, and has been changing ever faster since. He invented the electric telegraph in 1832. It took six more years for him to standardize a code for communicating over telegraph wires. In 1843, Congress gave him US$30,000 to string wires between the nation’s capital and nearby Baltimore. When the line was completed, he conducted a public demonstration of long-distance communication.

Morse wasn’t the only one working to develop a means of communicating over the telegraph, but his is the one that has survived. The wires, magnets and keys used in the initial demonstration have given way to smartphones’ on-screen keyboards, but Morse code has remained fundamentally the same, and is still – perhaps surprisingly – relevant in the 21st century. Although I have learned, and relearned, it many times as a Boy Scout, an amateur radio operator and a pilot, I continue to admire it and strive to master it.

Easy sending

Morse’s key insight in constructing the code was considering how frequently each letter is used in English. The most commonly used letters have shorter symbols: “E,” which appears most often, is signified by a single “dot.” By contrast, “Z,” the least used letter in English, was signified by the much longer and more complex “dot-dot-dot (pause) dot.”

In 1865, the International Telecommunications Union changed the code to account for different character frequencies in other languages. There have been other tweaks since, but “E” is still “dot,” though “Z” is now “dash-dash-dot-dot.”

The reference to letter frequency makes for extremely efficient communications: Simple words with common letters can be transmitted very quickly. Longer words can still be sent, but they take more time.

Going wireless

The communications system that Morse code was designed for – analogue connections over metal wires that carried a lot of interference and needed a clear on-off type signal to be heard – has evolved significantly.

The first big change came just a few decades after Morse’s demonstration. In the late 19th century, Guglielmo Marconi invented radio-telegraph equipment, which could send Morse code over radio waves, rather than wires.

The shipping industry loved this new way to communicate with ships at sea, either from ship to ship or to shore-based stations. By 1910, U.S. law required many passenger ships in U.S. waters to carry wireless sets for sending and receiving messages.

After the Titanic sank in 1912, an international agreement required some ships to assign a person to listen for radio distress signals at all times. That same agreement designated “SOS” – “dot-dot-dot dash-dash-dash dot-dot-dot” – as the international distress signal, not as an abbreviation for anything but because it was a simple pattern that was easy to remember and transmit. The Coast Guard discontinued monitoring in 1995. The requirement that ships monitor for distress signals was removed in 1999, though the U.S. Navy still teaches at least some sailors to read, send and receive Morse code.

Aviators also use Morse code to identify automated navigational aids. These are radio beacons that help pilots follow routes, traveling from one transmitter to the next on aeronautical charts. They transmit their identifiers – such as “BAL” for Baltimore – in Morse code. Pilots often learn to recognize familiar-sounding patterns of beacons in areas they fly frequently.

There is a thriving community of amateur radio operators who treasure Morse code, too. Among amateur radio operators, Morse code is a cherished tradition tracing back to the earliest days of radio. Some of them may have begun in the Boy Scouts, which has made learning Morse variably optional or required over the years. The Federal Communications Commission used to require all licensed amateur radio operators to demonstrate proficiency in Morse code, but that ended in 2007. The FCC does still issue commercial licenses that require Morse proficiency, but no jobs require it anymore.

Blinking Morse

Because its signals are so simple – on or off, long or short – Morse code can also be used by flashing lights. Many navies around the world use blinker lights to communicate from ship to ship when they don’t want to use radios or when radio equipment breaks down. The U.S. Navy is actually testing a system that would let a user type words and convert it to blinker light. A receiver would read the flashes and convert it back to text.

Skills learned in the military helped an injured man communicate with his wife across a rocky beach using only his flashlight in 2017.

Other Morse messages

Perhaps the most notable modern use of Morse code was by Navy pilot Jeremiah Denton, while he was a prisoner of war in Vietnam. In 1966, about one year into a nearly eight-year imprisonment, Denton was forced by his North Vietnamese captors to participate in a video interview about his treatment. While the camera focused on his face, he blinked the Morse code symbols for “torture,” confirming for the first time U.S. fears about the treatment of service members held captive in North Vietnam.

Blinking Morse code is slow, but has also helped people with medical conditions that prevent them from speaking or communicating in other ways. A number of devices – including iPhones and Android smartphones – can be set up to accept Morse code input from people with limited motor skills.

There are still many ways people can learn Morse code, and practice using it, even online. In emergency situations, it can be the only mode of communications that will get through. Beyond that, there is an art to Morse code, a rhythmic, musical fluidity to the sound. Sending and receiving it can have a soothing or meditative feeling, too, as the person focuses on the flow of individual characters, words and sentences. Overall, sometimes the simplest tool is all that’s needed to accomplish the task.

I do hope you read this article in full because it contains much interesting information. Many people will not have a clue about The Morse Code and, as you can see above, it is still relevant.

Finally, I can still remember the The Morse Code after all these years!

Support the Orcas

If you can, please support this PDX event coming up on the 5th.

In my post that was my letter to Mr. Neptune, Colette left a reply that was a ‘heads up’ to an event being held in Portland, Oregon on October 5th. Ergo, this coming Friday.

Now the odds are that very few of you dear readers will be within reach of that event.

But that doesn’t stop me from promoting the event so that the details may be shared as far and wide as possible.

Here’s a news item taken from CBS News.

Then for those that would like more background on the Orca whale, let me republish the opening paragraphs of an item from Wikipedia.

The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as no animal preys on them. A cosmopolitan species, they can be found in each of the world’s oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas, absent only from the Baltic and Black seas, and some areas of the Arctic Ocean.

Killer whales are highly social; some populations are composed of matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.

The International Union for Conservation of Nature assesses the orca’s conservation status as data deficient because of the likelihood that two or more killer whale types are separate species. Some local populations are considered threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), capture for marine mammal parks, and conflicts with human fisheries. In late 2005, the southern resident killer whales, which swim in British Columbia and Washington statewaters, were placed on the U.S. Endangered Species list.

Wild killer whales are not considered a threat to humans,[6] but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.

A Letter to Mr. Neptune

Continuing my series on examining my navel.

Dear Mr. Neptune,

Your oceans of the world are truly breath-taking. The power you can display in the odd wave or million through to the tranquility you so often also display defy rational explanations.

I have had the profound experience of sailing upon your waters, dear Mr. Neptune, over a number of years sailing back and forth between Cyprus and Turkey. Not a long distance but still sufficient to experience being solo on a yacht day and night.

Tradewind 33 – Songbird of Kent. My home for five years.

Then on my way sailing back to Plymouth, SW England, the magical, almost primeval, feeling of being alone on the Atlantic Ocean. Looking up at the night sky, feeling so insignificant, so infinitesimally minute with 500 miles of open ocean in all directions and those stars above my head.

No question, that practically everything about your oceans is beyond the understanding of us humans. Indeed, I had to look up online how much water there is on Earth to discover there is:

It’s roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey.

Because I simply didn’t have a clue.

And knowing there are approximately 326 million cubic miles of water doesn’t help because I am still left not having a clue as to what that means!

So, thank goodness, Mr. Neptune this is all a ‘walk in the park’ for you!

But I do have a question for you.

What do you make of this?

The image is cropped from the following:

The description of these figures is:

Figure. (upper) Change in global upper-level (0–2000 m) ocean heat content since 1958. Each bar shows the annual mean relative to a 1981–2010 baseline. (lower) Annual mean ocean heat content anomaly in 2017 relative to a 1981–2010 baseline.

And it was taken from research undertaken by Lijing Cheng and Jiang Zhu and found on the web here.

Ocean Heat Content

Owing to its large heat capacity, the ocean accumulates the warming derived from human activities; indeed, more than 90% of Earth’s residual heat related to global warming is absorbed by the ocean (IPCC, Cheng et al. 2017). As such, the global ocean heat content record robustly represents the signature of global warming and is impacted less by weather-related noise and climate variability such as El Niño and La Niña events (Cheng et al. 2018). On the other hand, ocean thermal expansion due to ocean temperature change contributes substantially (30%~50%) to the sea level change, which can considerably influence human populations in coastal and island regions and marine ecosystems. Therefore, monitoring the OHC changes and understanding its variation are crucial for climate change.

Is it possible, Mr. Neptune, that even you as the master of all our oceans is worried about the future?

I hope not but I do fear your answer.

Sincerely,

Paul

Ghosts

Here’s that article I wanted to share with you.

The tallest lighthouse in Oregon has a haunted history

Yet there is more to Yaquina Head Lighthouse in Newport than these ghostly stories.


JAYMI HEIMBUCH   February 16, 2018

On a scenic basalt rock headland that juts almost a mile into the Pacific Ocean stands a beautiful white lighthouse. At 93 feet tall, the Yaquina Head Lighthouse, located in Newport, Oregon, is the state’s tallest lighthouse. It’s been guiding ships for 145 years.

First lit on August 20, 1873, the lighthouse has gained quite the storied history. And that includes two ghost stories.

One tale tells of a construction worker helping to build the tower who fell to his death. His body lodged between the double walls, never to be retrieved. He — and his ghost — have been sealed in ever since.

The second story is that in the 1920s, Keeper Smith went into town and left Keeper Higgins in charge. But Higgins fell sick and asked Keeper Story to take over. When Smith saw from Newport that the lighthouse beacon wasn’t lit, he rushed back to find Higgins dead and Story drunk. Story, overtaken with guilt, feared the ghost of Higgins and from then on would take his bulldog up the tower with him.

As with most ghost stories, the authenticity of these is highly doubted. The first story is unauthenticated, and the second story is impossible. As Lighthouse Friends clarifies:

A great tale, but unfortunately not supported by the facts that Story and Higgins didn’t serve at the same time at Yaquina Head and Higgins didn’t meet his demise in the tower. Rather, Higgins left the Lighthouse Service before 1920 and returned to live with his mother in Portland. Second Assistant Keeper did die of a heart attack in the watchroom atop the tower in March 1921, but he too served before the arrival of Frank Story.

Fortunately, much more than ghosts can be seen at Yaquina Head Lighthouse. The lighthouse stands on what is now the Yaquina Head Outstanding Natural Area, one of the most spectacular

spots on the coast for viewing ocean wildlife such as sea birds and harbor seals at close range, as well as traipsing through tide pools at low tide. An interpretive center highlights information about these wild inhabitants and features exhibits on the historical details of the lighthouse.

The original oil-powered light has given way to an automated first-order Fresnel lens and a 1,000-watt globe. It flashes with its own specific pattern: two seconds on, two off, two on, and 14 off. The pattern is repeated around the clock.

While a little illumination causes the ghost stories to fade, visitors can still see a lot with a visit to Yaquina Head. Whether it’s grey whales at close range during their migration, or the sun setting over the ocean and silhouetting the tall structure, visitors are always happy they stopped to take in both the scene and the history of this special place.

I really hope that despite the advance of digital GPS navigation systems it will still be a very long time before these magnificent lighthouses are turned off!
