Shifts in the demersal fish community of South Georgia
Abstract: 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 ...

Krill faecal pellets drive hidden pulses of particulate organic carbon in the marginal ice zone
Abstract: The biological carbon pump drives a flux of particulate organic carbon (POC) through ... the ocean and affects atmospheric levels of carbon dioxide. Short term, episodic flux events are hard ... estimates. We model the potential hidden flux of POC originating from Antarctic krill, whose swarming ... behaviour could result in a major conduit of carbon to depth through their rapid exploitation of ...
