2 Acoustic Doppler Current Profiler observations during the JGOFS AESOPS Antarctic Polar Front Process Studies and : R/V Revelle Cruises from 3-Nov-97 to 3-Jan-98 and 13-Feb-98 to 19-Mar-98 S. D. Pierce J. A. Barth T. J. Cowles College of Oceanic and Atmospheric Sciences Oregon State University Corvallis, Oregon Data Report 176 Reference 99-5 December 1999 http.1/diana. coas. oregonstate. edu/sojgofs We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on RV Revelle during cruises R9711 (3 November 1997 to 3 January 1998) and R982 (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 nstruments 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. An online version of this report is available at n addition, the complete data sets and all processing details are available from the NODC Joint Archive for Shipboard ADCP: This work was funded by National Science Foundation grant OPP R!
