Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage
PIES on surface Lowered ADCP KAD and DRW with vacms


Our scientific objectives require time series of velocity as a function of depth, from near-surface to sea floor, measured on a lateral spacing that resolves the mesoscale eddy field, and with time interval shorter than weekly to avoid aliasing by rapid barotropic variability. To meet these needs we deployed an array of CPIES, which will measure the Antarctic Circumpolar Current across Drake Passage and map the circulation and eddy currents within a local dynamics array centered in the region of highest Eddy Kinetic Energy within Drake Passage. The array was deployed in 2007 and will be recovered in December 2011.
