SC-CAMLR-VII/BG/24 Mostrar menos información	Shifts in the demersal fish community of South Georgia United States of America Resumen: The heavily exploited fish stocks of South Georgia have been declining since the early 1970's. Use of a non-parametric method revealed a significant change in this community from the 1986/87 survey to the 1987/88 survey. This change was the result of reductions in the abundance of Champsocephalus gunnari and Notothenia squamifrons, and the increased presence of Pseudochaenichthys georgianus.

SC-CAMLR-VII/BG/26 Mostrar menos información	Distribution of phytoplankton in the mixed layer: implication of krill abundance United States of America Resumen: The vertical trajectory of phytoplankton in the Antarctic ocean is modelled as a random walk with a diffusivity derived from a simple Ekman layer model and turbulence theory. The surface mixing layer is shallow, but diffusion is large enough to effect the vertical distribution of phytoplankton in the upper ocean.
