Nella Dan: SIBEX II Cruise - Oceanographic and nutrient data

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, nitrite (insignificant concentrations), phosphate, silicate) data obtained from the Second International BIOMASS Experiment (SIBEX II) cruise of the Nella Dan, during January 1985. This cruise is the fourth in a series of six cruises, conducting a long term field survey on krill and other zooplankton. 64 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 44 of the stations. Casts were made to 1000 m or to near bottom if shallower. Oceanographic and nutrient sampling was done a supplement to the krill research program, and therefore was not always ideal for oceanographic purposes.The fields in this dataset are:cruise namestation numberdatestart timeship namestation positioncast depthsea bottom depthDepthNitrateNitritePhosphateSilicateManganese (Mn)PressureTemperatureSalinitySigma-TSpecific Volume AnomalyGeopotential AnomalyNumber of samplesTemperature DeviationConductivity DeviationThis dataset was updated by Angela McGaffin to include a summary excel file.
