Warreen hydrology and plankton data from SE Australia 1938-1942

This dataset contains hydrological and plankton data collected by FRV "Warreen" over the period May 1938-July 1942 in south-eastern Australian waters. Data included comprise depth, temperature, phosphate, nitrate, pH, dissolved oxygen and chlorinity readings, and the results of plankton net tows reported as abundances of crustacea (including krill and copepods), chaetognaths, coelenterates, fish eggs and larvae, mollusca and tunicates. Voyages in 1938-1939 were largely exploratory in nature, while those in 1940-1942 aimed at biannual sampling of specified transect lines ranging from Byron Bay to off Tasmania. Details of fish collections from these voyages were published elsewhere. "Warreen" was seconded for war work in September 1942 and this sequence of observations ceased. The data were published in 2 volumes of CSIRO's "Oceanographical Station List" series. Volume 1 of the published data is prefaced by a description of the "Warreen". Additional data was added in Dec 2010 with the digitization of the zooplankton records from the Warreen cruises of 1938-1942. This dataset includes surface zooplankton observations with synoptic oceanographic conditions.
