We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on RIV Revelle during cruises R9711 (30 November 1997 to 3 January 1998) and R9802 (13 February 1998 to 19 March 1998). The cruises were conducted as part of the Southern Ocean JGOFS (Joint Global Ocean Flux) Antarctic Polar Frontal Zone program. The ADCP was an RD Instruments hull-mounted 153-kHz narrowband unit. Data were collected nearly continuously during these Spring and Summer Process cruises, using an ensemble averaging interval of 2.5 min and a vertical bin length of 8 m. To reference the velocities to earth coordinates, we used GPS navigation in combination with the ship's gyrocompass and a GPS attitude system.
