Icescape and Cape Petrels
View from ship: Pack ice and seabirds in the Bransfield Strait, just South of King George Island in the South Shetland Islands. Cape petrels fly above colorful pack ice in Antarctica. The yellow-brown color in the ice is caused by a dense population of phytoplankton (primarily diatoms). Phytoplankton are marine algae. Each one is so small you can only see it with a microscope, but large numbers collectively change the color of the ocean and ice. Phytoplankton are primary producers and form the foundation of the Antarctic food web.
