摘要：

Our comparison of macrobenthic biomass, production and productivity of the Magellan region (14 - 349 m water depth) and the Weddell Sea (132 - 548 m water depth) is based on multi box corer samples collected in both areas Biomass is slightly but not significantly lower in the Magellan region (7.3 g C m(-2)) than in the Weddell Sea (12.0 g C m(-2)). Annual production and P/B ratio are higher in the Magellan region (5.1 g C m(-2) y(-1), 0.7 y(-1)) as compared to the Weddell Sea (3.6 g C m(-2) y(-1), 0.3 y(-1)). In the Magellan region, Mollusca, Polychaeta and Arthropoda dominate benthic production, whereas in the Weddell Sea Polychaeta, Porifera and Echinodermata are the most productive taxa.
