This report describes the seventh repeat hydrography section across Drake Passage, first established during the World Ocean Circulation Experiment. Thirty CTD/LADCP stations were carried out across the 753 km section from Burdwood Bank to Elephant Island, plus one test station, one station in Drake Passage to provide sound speed information for concurrent geophysical activities, and one station at the Rothera Time Series (RaTS) site, just off Biscoe Wharf at Rothera. Maximum station spacing on the section was 33 km, with stations closer together on the continental shelves. Water samples were drawn for salinity analysis, for subsequent CTD conductivity calibration. The LADCP was a new 2-instrument setup comprising upward – and downward–looking RD Instruments Workhorse ADCPs. The CTD was a SeaBird 911plus with dual temperature and conductivity sensors. Various underway measurements included navigation, vessel-mounted ADCP, sea surface temperature and salinity, water depth and
