Title of datasetMacronutrient data collected by RRS James Clark cruise 02 in the Bellinghausen Sea (Southern Ocean), Nov -Dec 1992
Narrative summary of datasetThe dataset comprises macronutrient (nitrate, nitrite, phosphate, silicate, ammonia/ammonium) data collected on RRS James Clark Ross cruise 02 in the Bellinghausen Sea in the Southern Ocean. The data were collected between 26 November and 18 December 1992 as part of an integrated ecosystem analysis. They form part of a more extensive dataset collected over 30 years, between 1980 and 2009, by the British Antarctic Survey.
Summary of processing methodologySamples for vertical profiles were collected from water bottles attached to a CTD rosette. Chemical analyses were undertaken using a custom-built Segmented-Flow Analyser initially based on Chemlab colorimeters and Ismatec proportioning pumps until 1993 when Technicon colorimeters were adopted. Initially, data were logged to paper chart and processed manually but in the mid-1980s, data extraction was automated and processing was managed with a digitising tablet and associated PC. In 1993 as part of a comprehensive re-build, data were logged to a PC. Data acquisition and subsequent processing was achieved with custom-built software (BAS in-house and Cambridge Beacon Ltd) and this was updated further in the mid-1990s when National Instrument data acquisition programmes were used to collect data, and calibration along with data organisation were switched to commercially available spreadsheets.
