A bio-optical approach to phytoplankton community sturcture, physiology and primary production on the Weddell Gyre
Includes bibliographical references. The Southern Ocean is an important “sink” for anthropogenic CO2, but it requires a detailed understanding of the sensitivity of the biological carbon pump to variability in physical forcing mechanisms in order to predict its continuing role. However, due to the r...
