Abstract/Summary

RRS James Clark Ross cruise JR16002 included work contributing to two National Capability projects. Bottom pressure recorder (BPR) landers previously deployed on the northern and southern continental slopes of Drake Passage to monitor ACC transport as part of Antarctic Circumpolar Current Levels from Altimetry and Island Measurement (ACCLAIM) were recovered, wrapping up a 28-year time series. The twenty-second complete occupation of the Drake Passage GO-SHIP section SR1b obtained full-depth temperature, salinity, and lowered ADCP velocity profiles at 30 stations, along with water column samples for oxygen isotope analysis and with underway measurements, with the objectives of investigating and monitoring interannual variability and trends in Antarctic Circumpolar Current structure and property transports and Southern Ocean water mass properties as part of Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA). Deployment of three Deep Apex autonomous profiling floats was also intended to contribute to ORCHESTRA as well as the global Deep Argo programme.
