Temperature, linearly interpolated from CARS2000 mean and seasonal fields to 0.1 degree spaced grid, at depths of 0, 150, 500, 1000 and 2000 metres. The loess filter used to create CARS2000 resolves at each point a mean value and a sinusoid with 1 year period (and in some cases a 6 month period sinusoid - the "semi-annual cycle".) The provided "annual amplitude" is simply the magnitude of that annual sinusoid. CARS is a set of seasonal maps of temperature, salinity, dissolved oxygen, nitrate, phosphate and silicate, generated using Loess mapping from all available oceanographic data in the region. It covers the region 100-200E, 50-0S, on a 0.5 degree grid, and on 56 standard depth levels. Higher resolution versions are also available for the Australian continental shelf. The data was obtained from the World Ocean Atlas 98 and CSIRO Marine and NIWA archives. It was designed to improve on the Levitus WOA98 Atlas, in the Australian region. CARS2000 is derived from ocean cast data, which is always measured above the seafloor. However, for properties which do not change rapidly near the seafloor, this would not lead to a significant error. All the limitations of CARS2000 also apply here.

This dataset series comprises deck logs from the vessel "Rama" in which observations made during the Gulf of Carpentaria Prawn Survey are recorded. This survey was conducted jointly by the Queensland State and Commonwealth Governments during 1963-1965 to examine the prawn resources of the south-eastern corner of the Gulf of Carpentaria.

Northern Prawn Fishery fishers' GPS plotter data collected between 1977 and 1997. The data indicates which areas in the Gulf of Carpentaria are considered untrawlable.

This dataset series comprises fish species composition data collected during the survey conducted jointly by the Queensland State and Commonwealth Governments during 1963-1965 to examine the prawn resources of the south-eastern corner of the Gulf of Carpentaria. Aubrey Harris retrieved the data from Rainer and Munro c.1984 - and it was used by Aubrey Harris and Ian Poiner for analysis for their paper (Harris, A. N. M. and Poiner, I. R. (1991)).

This dataset series comprises fish species composition data collected during the trawl and bottom sediment survey carried out in April 1985 and April 1986. This data was collected and used to compare fish abundance for this region with the pre-trawling surveys done by Munro between 1963 and 1965. Sediment samples were collected during the 1986 survey.

This product (i.e. an Access database and csv files) contains data (longitude, latitude and physical data) that explains the predicted spatial patterns of benthic habitats for demersal fish and benthic invertebrates in the NMR. Predicted patterns for habitats represent point data on a 0.01 decimal degree grid covering most of the NMR (approximately 400,000 square km).
-
This product (i.e. Access data base) contains data (longitudes, latitude and biodiversity attribute variables) that describes the predicted spatial patterns of biodiversity categories based on species richness and evenness of demersal fish in the NMR. This product provides predictions for total species abundance, species richness and species evenness and estimates of uncertainty for demersal fish. The predicted patterns are represent as point data arranged on a 0.1 degree grid (~ 1.2 km2) covering depths 50-1500 metres in the NMR

Prawn trawl data from Weipa, East and South East Gulf of Carpentaria in the late 1970s. The main objective was to ascertain the distribution and abundance of each of the main commercial and some non-commercial penaeid species. The main data collection was performed off the Judy B with cruises repeated every month for 13 months; some other vessels were involved at different times (Kalinda, Raptis Pearl, Sprightly). Trawling was conducted at night and consisting of 30 minute shots. All prawns were sorted by species (general codes used) and sex, but no weights were recorded. Catch rates were expressed as number of prawns caught per net per hour. There were more than four sampling plans.

The objectives of this project were: To design and implement a survey program to augment the historical survey data used for species split with contemporary, well-targeted and spatially precise data. This survey to be trialled in 2002-3 and confirmed in 2003-4. To establish a protocol so that such surveys can be quickly designed and implemented on an ongoing monitoring basis. To develop further the species split methods first proposed in FRDC 98/109 so that they can be used confidently in any new stock assessments. To re-examine the historical survey data as part of the strategy for the above and to report, particularly on the value of size class information for this purpose. To investigate and report on the potential use of electronic logbooks for enhancing the precision of stock assessment of Tiger prawn species, particularly on a spatially local scale. To investigate and report on the use of size class data for gaining some information on recruitment patterns for the stock assessment.

Data was collected on the FRV Southern Surveyor cruise SS 02/97 to define bycatch from prawn trawlers around the coast of the Gulf of Carpentaria from Cairns to Darwin in 20-40m depth.
