Antarctic Food Webs
The main objective of this proposal is to develop and validate satellite-driven species distribution and abundance models for the West Antarctic Peninsula (WAP). This objective will be achieved by integrating the results of two component efforts. The first encompasses a “top-down” historical time series analysis of existing space-based and in-situ measurements of WAP phytoplankton, krill and penguin distribution and abundance data from the Palmer Long-Term Ecological Research Station (PAL LTER). The second is represented by a “bottom-up” field program focused on spatially predicting the foraging locations of the Adélie penguin. This field effort links space-based platforms, AUV’s and animal-borne sensors. The results of this work will, 1) quantify the ability of satellite data streams to capture and describe the climate driven ecological changes in the WAP and, 2) predict how Adélie penguin foraging locations and their associated biodiversity will change if warming trends continue.
