Description

The overall objectives of Palmer LTER research are to document and understand the phenology and variability in sea ice dynamics, primary production, zooplankton ecology, seabird and marine mammal demography, microbial and biogeochemical processes in the Antarctic marine ecosystem, including identifying the mechanisms of ecosystem response to climate variability and rapid climate change. Our overarching objectives are to continue the 25-year long LTER time series on our regional scale grid of hydrographic stations west of the Antarctic Peninsula and maintain regular twice weekly sampling around Palmer Station. The sampling region extends from Palmer Station south to Charcot Island and encompasses areas both more and less affected by climate change. Unattended moorings, drones and gliders expand sampling capabilities in space and time. During this 6-year project cycle, we continue to study seasonal-scale processes at Palmer Station, with field sampling and specific, intensively focused laboratory experiments to test hypotheses generated from the fieldwork. This experimental work requires close coordination between our Station-based and LMG-based field teams for sampling and experimental logistics. Palmer Station continues to be the focus of intensive study of Adélie, Gentoo and Chinstrap penguins, and the effects of climate change on their breeding biology, foraging ecology and population dynamics. We will link visual survey and satellite-based tracking of baleen whales with LTER synoptic data to offer unprecedented insights into how the distribution and abundance of these krill predators relates to environmental variability and how it will be affected by climate change.
