A proposal for large scale sampling of krill in the diet of predators across Area 48 to coincide with the CCAMLR synoptic survey
Abstract: There is a high degree of spatial and temporal variability in the population of ... Antarctic krill Euphausia superba across the Scotia Sea. Resolution of the spatial component of this ... variability requires a 'snapshot' of the krill population over the region (eg the CCAMLR B0 survey ... ) whereas temporal changes have been addressed using time-series of samples from the diet of predators. At ...
