1. Preliminary results of the experiments on the krill transport study in the South Orkney area (April 1992)

   area. The krill biomass was estimated within the square at the start and the end of works. It amounted ... assessment of krill density and oceanological stations were carried out along the square perimeter. Four ... average estimates of krill density were obtained by 15-miles intercepts of the perimeter, along with mean ... water flow and geostrophic currents. The balance of krill input and output for the square was calculated ...

4. Characterising the preferred at-sea habitats used by chinstrap penguins and the fishery for Antarctic krill: slow-flowing, nearshore waters over shallow bathymetry

   habitats are also locations preferentially used by the commercial krill fishery. Cross-shelf submarine ... canyons occur near to a number of preferred krill fishing locations, suggesting that these canyons ... potentially play an important role in krill transport onto the shelf. In the relatively slow-moving shelf ... waters krill depletion is probably more likely and krill replenishment less likely. Our results suggest ...
