A RE-APPRAISAL OF THE TOTAL BIOMASS AND ANNUAL PRODUCTION OF ANTARCTIC KRILL
Abstract: Despite much research on Euphausia superba, estimates of their total biomass and ... revisions in acoustics have made it possible to refine previous estimates. Net-based databases of density ... and length frequency (KRILLBASE) yield a summer distributional range of ~19 x106 km2 and a mean total ... abundance of 8x1014 postlarvae with biomass of 379 million tonnes (Mt). These values are based on a ...

The incidence of plastic in the diets of Antarctic seabirds
Abstract: We investigated the diets of seabirds at sea in the Antarctic from 1976 to 1988. During ... , we collected or pumped the stomachs of 1,223 seabirds of 23 species. The stomach contents of species ... live prey. Among species that feed a t the surface, most of which eat both live and dead organisms ... , incidence of plastic was highest among the smaller ones and those that are omnivores, or feed on zooplankton ...
