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 ...

COMPARING CEMP INDICES TO INFORM FEEDBACK MANAGEMENT OF THE ANTARCTIC KRILL FISHERY
to adjust activity of the Antarctic krill fishery based on the state of krill-dependent predators is ... a recognized goal of the CCAMLR. We suggest that progress toward a feedback management approach can ... population can be assessed by measuring trends in the difference between the observed states of a “treatment ... ” and a “control” population. As the states of these monitored populations change relative to each other ...

Histopathology of Antarctic krill, Euphausia superba, bearing black spots
Abstract: Small black spots have been noticed on the cephalothorax of Antarctic krill, Euphausia ... superba, since January, 2001. To study the nature of the black spots, the krill were sampled in the winter ... of 2003, 2006, and 2007 in the South Georgia region, the Antarctic Ocean. Histological observations ... revealed that the black spots were melanized nodules that were composed of hemocytes surrounding either ...
