Supporting Stations:  ARSV Laurence M. Gould
Research Locations:  West Antarctic Peninsula

Project Description:
This LTER component takes responsibility for processing and analyzing hydrographic data. The data are used to describe the hydrography and circulation in the Palmer area in particular, and the Western Antarctic Peninsula (WAP) region in general, with a focus on developing circulation and coupled physical-biological models. The Antarctic shelf regions are influenced by circumpolar deep waters, and the circulation pattern in the region shows large-scale flows influenced by topography.

Field Season Overview:
No project participants deploy. During the annual 28-day LTER cruise onboard the Laurence M. Gould (LMG) LTER participants conduct bioacoustic surveys using the Biosonics DT-X echo sounder at least three times per week. The goal is to identify krill patches and gain an understanding of krill distribution patterns in the nearshore.
