The Weddell Sea is situated off the coast of Antarctica, at the southernmost part of the Atlantic Ocean. Its coordinates are 75 degrees south and 47 degrees west, encompassing the Argentine, Chilean, and British territories of Antarctica.

Polar bear encounter in Spitsbergen

I watch the sea ice from the bridge of a ship in one of the fjords of Spitsbergen, an archipelago north of Norway. I observe a perfectly adapted animal moving on the ice, the results of hundreds of thousands of years of ecological fine-tuning. Snowshoe-sized paws distribute weight, fur handles the cold and sunlight to perfection, and an incredible sense of smell samples this monochromatic realm.

How and When Did Greenland Become Covered in Ice?

Although it may be hard to believe, there was a time when Greenland was more green than icy. Today, those who embark on a Greenland expedition are greeted with views of the Greenland ice sheet and the marine life that thrives in this region, including seals and whales. Polar bears are also prominent in the northern and eastern parts of Greenland. These animals have adapted to their environment, but a few million years ago, the massive island would not have been as welcoming to them.

Navigating by touch through the sea ice

Ships are meant to glide effortlessly through calm waters, but our Greenland expedition vessel Ortelius is shuddering and wiggling as it navigates through the calm yet frozen waters between Svalbard and the islands. We’re on the North Atlantic Odyssey, a journey that starts in continental Europe and concludes near the North Pole in Svalbard. Onboard are 115 enthusiastic passengers. Most of them are currently on the outer decks, cameras in hand, captivated by the sea ice.
