Total zooplankton biomass (g dry weight) were recorded from stepped oblique bottom to surface plankton tows, using a 140-142 micron net. The data also includes a corrected biomass value, allowing comparisons to be made with later data collected using a 250 micron net size. Data were collected during nine cruises that took place between 1975 and 1977 on chartered boats and the "Kalinda". Related datasets include the counts of prawn larvae from these tows.

Banana prawn sampling was carried out in the Norman River for four seasons to measure immigration, residents and emigration. In 1979, four other river systems in the surrounding area were sampled to look at geographic variation.

Hydrographic data from six cruises, between April 1976 and March 1977 in the Gulf of Carpentaira are presented. Physical quantities (temperature, salinity and sigma-t) and chemical properties (dissolved oxygen, nitrate and silicate) were measured, and are presented in an associated report both as values at the stations and as contour maps. These cruises began in 1975 with the initiation of the CSIRO Tropical Prawn Research Project, a new series of Gulf-wide cruises undertaken to study the larval ecology of penaeid prawns. Approximately 70 stations were occupied on each cruise (with the exception of KL 7/76 which made only three transects in the southern Gulf). Two types of hydrographic stations were undertaken. Type 'A' stations consisted of Nansen casts with bottles every 10m from the surface to the bottom, sampling temperature, salinity, oxygen, nitrate plus nitrite, nitrogen and silicate. Type 'B' stations were Nansen casts with three bottles (at the surface, at 10m depth and within 10m of the bottom) sampling the same parameters as the Type 'A' stations. The sigma-t values were calculated from the temperature and salinity values, and the percentage of oxygen saturation was calculated from the oxygen concentration, temperature and salinity data. The difference between surface and bottom values was also calculated for all properties. The six cruises included: FRV Kalinda: KL 4/76 April 1976 KL 7/76 June 1976 KL 9/76 September 1976 FV Judy B: JB 2/76 November 1976 FV Raptis Pearl: TP 1/77 January 1977 RV Sprightly: TP 3/77 March 1977
