The Palmer Antarctica Long-Term Ecological Research project (PAL LTER) studies on the effects of climate change on the marine ecosystem west of the Antarctic Peninsula. The project is over 30 years running. Our research team studies the whole food web, from bacteria to phytoplankton and zooplankton, to penguins and whales. My group focuses on the zooplankton, such as krill, which play a central role in the Antarctic marine food web.
