Avian Island Travels

The research team is currently heading back to the United States.  The following blogs will feature some of the work and observations from their travels.

On January 18, the research team visited Avian Island.   Avian Island (Latitude 67°46′ S, Longitude 68°54′ W, 0.49 km2), is a very small island situated in northwestern Marguerite Bay,  south of Adelaide Island on the western side of the central Antarctic Peninsula (see map):

Avian Island is a small island south of Adelaide Island. Avian Island does not appear on this map because it is only 0.7 miles (1.2 km) long.

This trip to Avian Island allowed the AQ team to rendezvous with two birders (Jen and Cameron) who had been studying these animals for the last 5 days.  This is a special place for scientists interested in birds because Avian Island is home to 35,000-70,000 breeding pairs of Adélie penguins. If you recall, we encountered these pengiuns in an earlier post.  Both parents and their babies were filmed at Avian Island. When they arrived, the weather on Avian Island was snowing, wet and cold and these penguins don’t like snow. Adélie penguins are designed for colder, drier environments and the snow can be harmful to their eggs and nests.

Filming had its challenges too.  Dena Seidel and Chris Linder report that they stepped in and out of puddles of penguin pee for hours filming the birds and elephant seals.

Filming and Learning in Antarctica

Dena Seidel reports the “science continues to be amazing.”

Here are 2 photos from Antarctica – one taken on Humble Island interviewing penguin scientist Donna Fraser (you may recognize the penguins from an earlier posting) and the other taken on the glacier behind Palmer station with scientist Reide Corbett, who is studying glacial runoff but is not part of the Long Term Ecological Research project.

Meet the Adélie Penguins

Dear all,

We spent today (January 3) filming Donna Fraser and her team tagging Adélie penguins (Pygoscelis adeliae) on Humble Island, a small island off of Palmer station. This population of Antarctic penguins is rapidly declining due to retreating sea ice. They are dependent on the sea ice, and the accompanying krill, for their survival. The penguins had many chicks that they were shading from the hot sun.  Here are three photos taken from the film footage.

We are now at Palmer station until Saturday morning when we begin the month long science cruise. This is all quite amazing and our students will learn a great deal from working this project.
