An interdisciplinary team of researchers will focus on describing the high productivity patchiness observed in phytoplankton blooms in the mid to late summer in the Ross Sea, Antarctica. Key hypotheses to be tested and extended are that intrusions of nutrient and micro nutrient (e.g. Fe) rich water masses of the Antarctic modified circumpolar deep water (CDW) up onto continental shelves act to control the biogeochemical response of a large area of the productive Ross Sea coastal region. It is believed that this enhanced productivity may be a significant contributing factor to the global carbon cycle.

A novel sampling strategy to be used to test the above hypotheses will employ a remotely controlled deep (1000m) glider (AUV) to locate and map CDW in near real time measuring C (conductivity), T (temperature), D (pressure) and apparent optical properties, and which will serve to direct further ship-based sampling.

The adaptive coordination of a polar research vessel with an AUV additionally provides an opportunity to engage in formal and informal education and public outreach on issues in polar research.
