Paulet Island and Antarctic Sound

Feb 12, 2019 - National Geographic Orion


Today was our final day of expedition here at the Antarctic Peninsula. We were still exploring territory surrounding the Antarctic Sound. This water body extends approximately 30 nautical miles long and between seven and 12 nautical miles wide, separating the Joinville Island group from the peninsula.

We landed on Paulet Island in the morning, one first discovered by the British Antarctic expedition under James Clark Ross (1839-1843), which he named in honor of Admiral Lord George Paulet of the Royal British Navy. This volcanic island attracts more than a hundred thousand pairs of Adélie penguins on an annual basis, though Paulet Island is certainly better known for the downing of Antarctic in 1903, the remnants of which tell of a scientific expedition gone awry.

The Swedish-led vessel was crushed and sunk by ice off the coast of Paulet Island while on its way to pick up expedition leader Otto Nordenskiöld and his crew. The scientists with him had spent that winter on Snowhill Island collecting a massive number of rock samples, fossils, and other important specimens and data for research. The group of 20 men from the wrecked Antarctic rowed to Paulet Island in their lifeboats and built a stone hut for shelter. They subsisted primarily on penguin, and all but one survived. The crew did manage to outlast the harsh Antarctic winter and were later rescued by the Argentinian Navy.

Around lunchtime, whale expert Conor Ryan announced that there was spectacular whale activity happening out in the Antarctic Sound. Guests could see at least a dozen minke whales, a big group of small type-b killer whales, and fin whales—all together and along both the bridge and the ship’s bow.

The small type-b killer whale is known for hunting penguins, but with no penguins in the water, and the whole group staying that close to other whales for as long as they did, is it possible these orcas were feeding on silver fish? It’s difficult to say at a distance, and the dark waters of the Arctic don’t let off much to its mysterious subsurface. Still, it was an absolute treat to see these three species interact for such a long duration!

About the Author

Andreas Madsen

Naturalist

Andreas was born in the village of Ebeltoft on the central east coast of Denmark and has spent his childhood years with the sea and open fields as neighbours. For a child of the North, fishing, bicycling, skiing, and hiking come along with your first steps and nature has always had a self-explanatory role in Andreas’ life. Between studies he left Denmark to travel and it was during his months in South America he discovered his curiosity and interest for geology. In 2013 he left Ebeltoft for the big(ger…) city Aarhus to begin his geology studies at Aarhus University. During his five years there he has been involved in different types of research projects, taking him to remote places such as Iceland, Svalbard, Greenland, and the Geographic North Pole. His latest research project, which investigates aspects of narwhal biology and ecology from a vessel in Scoresby Sound, Greenland, has been ongoing since 2017.

About the Photographer

Conor Ryan

Naturalist

Hailing from Cobh in the south of Ireland, Conor Ryan grew up on the shores of Cork Harbour where his fascination with the sea led him to study zoology at University College Cork. He continued his studies in marine biology in Galway, where he completed his Ph.D. thesis on the diet and population structure of baleen whales in the Celtic Sea using stable isotope analysis. His research also brought him to Cape Verde in search of the breeding grounds of humpback whales that frequent the coasts of Ireland. However these whales have not yet given up their secret!
