West Antarctic Peninsula:

The subject of our study Northern most part of Mainland

Antarctica Susceptible to climate changeexperiencing

rapid warming (alters sea ice dynamic/ecosystem interaction) Effects glaciers! Phytoplankton affected surfacechlorophylldecreased 12 % !

Rise of half degree Celsius each decade We examined time frame 2007-2011

Palmer Long Term Ecological ResearchProject (LTER)

Construction of the U.S. Antarctic station was completed in 1968,replacing 'Old Palmer' that was established in 1965.

Palmer LTER established in 1990.Marine ecology of the Southern Ocean focused on:

physical forcing (atmospheric, oceanic and sea ice) of theecosystem with emphasis on the ecological consequences of sea-ice variability

biological processes with emphasis on microbial, primaryproduction and the life-history parameters of secondary

producers (krill) and apex predators (penguins)physical/optical/chemical/biological modeling that linksecosystem processes to environmental variables.

Goal: To understand the Antarctic ecosystem using a series

of data sets to determine how the climate is changing andits affects on the West Antarctic Peninsula
