This was the sea ice in the Antarctic Sound that we encountered on our way to Brown Bluff on the Antarctic Peninsula. Our plans to venture further south into the Weddell Sea were thwarted by how much ice was still present. In the center right a few Adelie Penguins are visible. The brown stains on the ice are penguin guano, evidence of how many penguins use the ice as areas of rest and protection from predators (mainly Leopard seals and Orcas) when they are hunting for krill their major food source.
