Research Locations: Antarctic Peninsula
This interdisciplinary field program addresses the rapid, system-level changes now taking place in the Larsen B Embayment, Weddell Sea region of the Antarctic Peninsula, where the ice shelf underwent a spectacular collapse in 2002. Ice core scientists, glaciologists, oceanographers, marine geologists and biologists are collaborating to characterize the effects of the collapse on the marine ecosystem as well as on glacial dynamics and interactions between the ocean, ice, geology and biology. The project aims to place these changes in the context of past changes in the region occurring on timescales ranging from decadal to the penultimate interglacial (125,000 years before present) when it is thought to have been warmer, and the sea level higher, than today.
Field Season Overview:
Six participants will deploy onboard LMG12-11 for five science days of ship time aboard the ARSV Laurence M. Gould. Their tasking includes installing new cGPS stations and upgrading existing ones, obtain sediment cores (Kasten and jumbo pisten) along the southern Gerlache Grounding Line, and deploy the yoyo digital bottom camera in Brialmont Cove (near Spring Point). Throughout much of the work they will also collect water samples using pumps or CTDs.
