Abstract: Ocean food webs modify the efficiency with which CO2 is absorbed from the atmosphere into the sea, fixed by phytoplankton in the surface layers and then transported to the ocean interior. This so-called &biological pump& buffers about one-third of the CO2 released from all human activities. Our priority is to understand the Southern Ocean ecosystem and its interconnections sufficiently well to be ... View entire text

Purpose: Objectives include:
1. To describe the spatial and temporal distributions of the major species within each food web.
2. To quantify the major energy flows.
3. To understand the key factors controlling energy flow in the food web including
a) responses to variable food supply and,
b) implications for carbon export
