Magga Dan Hydrology and Plankton Data, Southern Ocean Jan-Mar 1959

These data comprise measurements of surface temperature, salinity and phosphate from sea surface samples collected by an officer of CSIRO Division of Fisheries & Oceanography on board a routine supply voyage to Antarctica by the Antarctic Division's vessel M.V. "Magga Dan" in January-March 1959. Pigment samples (chlorophylls a, b, c and astacin) and CO2 uptake (productivity) were also measured at 0 and 25m depth at some stations, along with dry weights of zooplankton (plus phytoplankton) in 100m-to-surface plankton net tows. Phytoplankton counts were also stated to have been made although no data appear in the published list. The data were published in CSIRO's "Oceanographic Station List" series in 1960.
