Surface sampling data from merchant vessels, SE Indian Ocean 1956 (published data)

These data, reported in CSIRO's "Oceanographic Station List" series in 1957, comprise mainly measurements of surface temperature, and salinity (as chlorinity), from sea surface samples collected by the merchant ships MV "Dulverton", MV "Kabbarli" and MV "Duntroon". Sampling was only carried out in one year (1956). The merchant vessel sampling program was carried out at a time when the CSIRO Division of Fisheries had no dedicated ocean-going research vessel, as a means of acquiring information about offshore waters. In the volumes cited, similar data are also reported from the Tasman Sea, Coral Sea, and south-eastern Australian waters and Bass Strait.
