The NSF-funded Arctic Shelf Basin Interaction experiment uses the U.S. Coast Guard icebreaker Healy to explore the exchange processes between the shallow Chukchi and Beaufort shelf seas and the adjacent deep ocean basins to the north and west of Arctic Alaska.

The icebreaker contains sonars (so-called acoustic Doppler current profilers or ADCPs) to measure ocean current profiles contineously about every 4 seconds. We here present processed data from the ADCPs in ascii format with a graphical display of data locations separated into roughly daily data segments. All data were collected and/or processed by University of Delaware personel using single-ping raw data.
