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.

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

Here! Here!

One thought on “Waterfalls!

  1. Agree totally. It is unfortunate that certain people choose to believe that global warming isn’t occurring. Good share!
