Biological oceanographic processes in the Ross Sea, Antarctica: Paradigms lost?
The Ross Sea is one of the most important regions in the Southern Ocean, contributing significantly to the biogeochemical cycles and supporting a diverse and abundant food web, characterized by the world’s largest Adélie and Emperor Penguin colonies and supporting massive numbers of baleen whales, pelagic birds and seals.

Irradiance limits growth in spring, but iron limitation is common in summer. Vertical flux is substantial, and largely driven by aggregate formation. Characteristics of these “paradigms” are described.

The results of numerical models predicting future (+50 and +100 years) conditions suggest that drastic oceanographic and food web modifications will occur, with relatively unpredictable effects for higher trophic levels and biogeochemical cycles.
Hope to see many of you - everyone most welcome to attend!
