| Summary: | This report documents five early cruises in the Drake Passage annual repeat series conducted by Southampton Oceanography Centre in collaboration with the British Antarctic Survey. The series began under the auspices of the World Ocean Circulation Experiment as southern repeat section SR1b with a SeaSoar (towed undulating profiler) occupation in 1992. We document cruises from 1993 (JR0a), 1994 (JR0b), 1996 (JR16), 1997 (JR27) and 2000 (JR47). The cruises were all hydrographic CTD sections across Drake Passage between Burdwood Bank and Elephant Island, comprising 30 stations. One cruise (JR27) was occupied at higher resolution with 52 stations; also additional chemical measurements were made. On two cruises (JR16 and JR27), a lowered acoustic Doppler current profiler (ADCP) was introduced to provide full-depth water velocity profiles. Other measurements (vessel-mounted ADCP, sample salinity, navigation, expendable athythermographs, etc.) are described in context. |
