Progress towards a trophic model of the ecosystem of the Ross Sea, Antarctica, for investigating effects of the Antarctic toothfish fishery
Abstract: We report on the further development of a carbon-budget trophic-model of the Ross Sea ... Ross Sea is a low primary production system, with production being localised in space and time. In the ... balanced, due in part to limited information on diet fractions of Ross Sea organisms. Methods to adjust ...
