Nella Dan: FIBEX Cruise - Oceanographic and nutrient data

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, phosphate, silicate) data obtained from the First International BIOMASS Experiment (FIBEX) cruise of the Nella Dan, during Jan - Mar 1981. The cruise is the first in a series of six, providing a long term field survey studying krill and other zooplankton. 52 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 14 out of the 52 CTD stations. Casts were made to 2000 m or to near bottom if shallower. The oceanographic sampling was done as a supplement to the krill research program and the nutrient sampling to help interpret phytoplankton distribution and abundance, so sampling location and depth were not necessarily selected according to oceanographic or nutrient related considerations.
