CTD: until 2003, a Chelsea Instruments Aquapak was used, with sampling to 200m due to the depth rating. Since then an SBE19 and SBE19+ have been alternated between use on station and servicing in the UK. These have been calibrated during servicing and compared with an SBE911+ CTD on board R/V Laurence M. Gould on joint casts (SBE19 tied to frame) and samples analysed on a Guildline Autosal 8400B Laboratory Salinometer Ammonium: samples were measured on a Turner TD-700 fluorometer. Macronutrients: from 1998 to 2017, samples were analysed on QuAAtro39 segmented flow auto-analyser at NOCS https://www.southampton.ac.uk/oes/research/facilities/dissolved-inorganic-and-organic-nutrient.page . From 2017 to 2018, samples were analysed on a SEAL analytical AAIII segmented flow colorimetric auto-analyser (Woodward and Rees, 2001). Chlorophyll: samples were measured on a Turner AU-10 fluorometer. Oxygen isotopes: From 1998 to 2012, the delta-O-18 measurements were made with a SIRA 10 mass spectrometer plus Isoprep18 device. From 2012 to 2017, the delta-O-18 measurements were made with an Isoprime 100 mass spectrometer plus Aquaprep device.,Year-round measurements of the water column in Ryder Bay, Western Antarctic Peninsula have been collected by the Rothera Marine Assistant and associated researchers, starting in 1997 as part of the Rothera Oceanographic and Biological Time Series (RATS) to assess temporal variability in physical and biogeochemical oceanographic properties. The data were collected using instrumentation deployed from rigid inflatable boats, or through instrumentation deployed through holes cut in the sea ice when the bay is frozen over in winter. Data collected include profiles to about 500m depth with a conductivity-temperature-depth (CTD) system that produces measurements of temperature, salinity, fluorescence and photosynthetically-active radiation (PAR). Individual water samples are collected with a Niskin bottle from a standard 15m depth, with some samples also collected from the surface layer. These ...
