ObjectivesA two-leg cruise:
Part I was the first in a series of cruises to study interannual variability of the South Georgia marine ecosystem (CP1). This involves an annual study of:
A) The large scale physical and biological systems to the north and west of the Island, across the Polar Front.
B) The operation of the marine ecoysystem in the vicinity of South Georgia.
Objectives:
1. Undertake a standard biological-hydrographic transect across the Polar Front.
2. Undertake a series of hydrographic-hydroacoustic transects in two areas on the north shelf of South Georgia.
3. Station based and targetted biological and hydrographic sampling in two areas on the north shelf of South Georgia.
Part II was a focused study of the biological community of the Polar Frontal Zone to the north of South Georgia, emphasising seabird and squid interactions - a focused study of the biological community of the shelf-offshelf regions on the NW coast of South Georgia.
