Derwent Hunter Voyage DH 6/56 Hydrology and Plankton Data

This dataset comprises hydrological and plankton data collected on Derwent Hunter Voyage DH 6/56 in the Tasman Sea, between December 1956 and February 1957. The dataset contains measurements of temperature, chlorinity, dissolved oxygen and total phosphorus at 20 stations in vertical sections to maximum depths ranging from 200 to 1500m, surface wind data, comments on zooplankton species composition and abundance (copepods and salps) studied at 12 stations, and phytoplankton (diatoms and dinoflagellates) from 11 stations. There are also brief comments about tuna catches. The hydrology data are published in CSIRO's "Oceanographical Station List" series, and discussed in Division of Fisheries & Oceanography Report no. 12, where the cruise track and the biological data are given.
