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:
Eight participants will deploy onboard LMG13-11 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) in the Hugo Island Trough, in the vicinity of Barilari Bay, and in the basins between the Palmer Deep and Grandidier Channel. In addition they will complete a yo-yo camera transect at a few of the coring sites, and will collect water samples using a McLean pump and CTD.
