LTER: Ecological Response to “Press-Pulse” Disturbances Along a Rapidly Changing West Antarctic Peninsula

Climate change is predicted to have a significant impact on marine food webs. This is especially true for polar systems where ocean biology and chemistry are strongly tied to the presence or absence of sea ice. The Palmer Long Term Ecological Research program is focused on developing a fundamental understanding of the ecology of the marine food web along the West Antarctic Peninsula. This region is undergoing some of the most rapid changes on the planet, including rapid warming of the atmosphere and ocean, large reductions in sea ice, and major retreats in glaciers. These changes are causing major changes in the food web. The program has been tracking how all parts of the food web, from single celled plants to penguins and whales, have been responding to these changes. Not all parts of the food web have been impacted equally. The changes have broad implications beyond ocean ecology, as polar marine systems play an over-sized role in the global cycling of carbon. The project also anchors an extensive education and outreach program promoting the global significance of Antarctic science and research. Using the recently developed Polar Literacy Principles as a foundation, the project will maintain and expand the virtual schoolyard program via virtual fieldtrips and dissemination of new polar instructional materials for K-12 educators to facilitate their professional development and curricula. The project will also leverage the development of Out of School Time materials for afterschool, 4-H, and summer camp programs; develop and implement an art and science exhibition designed for use in higher education focused on engaging lifelong learners; and produce high-quality science communication resources to build awareness of the National Science Foundation research directly to audiences in the cruise ship industry and indirectly through social media. The project is broadening participation through a coordinated diversity, equity, and inclusion plan leveraging both virtual and traditional Research Experience for Undergraduates programs aimed at underrepresented students.
