Buoy, IOEB Doppler Current Profiler (ADCP) Data. Version 1.0

A 150-kHz narrowband RD Instruments Acoustic Doppler Current Profiler (ADCP) internally recorded 34,805 current ensembles in 362 days from an Ice-Ocean Buoy (IOEB) deployed during the SHEBA project. The IOEB was initially deployed about 50 km from the main camp and drifted from 75.1 N, 141 W to 80.6 N, 160 W between October 1, 1997 and September 30, 1998. The ADCP was located at a depth of 14m below the ice surface and was configured to record data at 15 minute intervals from 40 8m wide bins extending downward 320m below the instrument. The retrieved 24 Mb raw data are processed to remove noise, correct for platform drift and geomagnetic declination, remove bottom hits, and output 2-hr average Earth-referenced current profiles along with ancillary data.
