Ship underway data collected aboard the James Clark Ross during cruise no JR158 in 2007. Includes data from navigation and vessel-mounted ADCP (Acoustic Doppler Current Profilers). On the ship the position and observed data were interpolated to five-second records to merge the navigation with the underway data. These one-minute averages are averages over 12 of the interpolated points.
Argo floats measure temperature and salinity. Seven floats were deployed in November 2004 from the RRS James Clark Ross cruise JR110. Data were transmitted automatically to the British Oceanographic Data Centre (BODC).
The dataset contains oxygen stable isotope and salinity measurements from water samples collected from sea ice and meltwater pools in April 2016 in the region of South Georgia, Signy and deep within the Weddell Sea pack ice during the marine survey JR15006. The d18O and salinity measurements from sea ice and meltwater sources complement the same analysis from CTD casts and underway non-toxic flow water system on the RRS James Clark Ross during the JR15006. Establishing d18O and salinity values for saline water and oceanic freshwater components can be used to identify sources and changes of freshwater contributions to the ocean.
Two moorings were deployed and recovered using the James Clark Ross (cruise numbers: JR112/113, JR155). One was deployed in Ryder Bay at the Rothera Oceanographic and Biological Time Series (RaTS) oceanographic station midway between Rothera Point and Leonie Islands. The other was deployed in deep water in northern Marguerite Bay. The moorings were used to monitor particle flux, currents, salinity and temperature. Two sediment traps on each mooring were used to measure biogenic flux from surface waters to the seafloor and quantify changes down the water column.
