Megabenthos was sampled using a beam trawl at 105 sites throughout the Gulf of Carpentaria during the Southern Surveyor cruise SS 03/90. The megabenthos was identified, counted and weighed. The results were used in pattern analysis of the communities.
-
Two studies were carried out (October 1993 and March 1994) each lasting 24 hours, at one site in the Embley River, Gulf of Carpentaria. Juvenile prawn samples were collected every 2 hours by hand scoop or beam trawl in the river. Data were collected on gut fullness, moult stage, and prey type and number.
-
Seagrass aerial surveys were used to produce maps of the Groote Eylandt area. Samples of juvenile and sub-adult prawns were taken by beam trawl at Groote Eylandt, Blue Mud Bay and Sir Edward Pellew Islands under various sampling regimes between 1983 and 1989.
-
Megabenthos was sampled using a beam trawl, at 105 sites throughout the Gulf of Carpentaria during the Southern Surveyor cruise SS 03/90. The infauna was identified, counted and weighed. The results were used in pattern analysis of the communities. Data on sediment grain size were also collected.
-
Juvenile tiger prawns were collected by beam trawl in the Embley River, Gulf of Carpentaria in October 1993, March 1994 and October/November 1994. The following parameters were measured: prawn numbers, carapace length, species, seagrass, biomass, salinity, temperature and depth. Field experiments were carried out using enclosure nets.
-
Sampling was carried out in October 1993 and March 1994 to collect fish and juvenile prawns. Fish gut contents were examined. Sampling took place at two sites in the Embley River using gillnets, beach seines, rotenone, and beam trawls.
-
Sampling of juvenile prawns took place between 1981-1982. These samples were mainly taken from the Embley River and Albatross Bay region. Samples were collected using beam trawls, plankton nets and set nets. Data recorded include species and length frequency.
-
Fortnightly sampling of juvenile prawns took place over six years (1986-1992). These samples were mainly taken from the Embley River and Albatross Bay, plus one set that were taken from the Wenlock and Archer Rivers. Samples were collected using beam trawls, plankton nets and set nets. Data recorded include species and length frequency. As part of this project, monthly temperature and salinity measurements were also taken from transects in the Embley River. These data are often referred to as the "Embley River Hydro Dataset".
-
Juvenile prawn samples were collected by beam trawl at a number of sites between the Vanderlin Islands and Rose River (Numbulwar), Gulf of Carpentaria, to investigate the recolonisation of sand and seagrass habitats following Cyclone Sandy.

This record describes the catch data from the Marine National Facility (MNF) RV Investigator voyage IN2023_V05, titled "Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 1)." The voyage took place between 27 June 2023 and 29 July 2023 (AEST), departing from Hobart and returning to Hobart. The dataset contains catch data for specimens collected by Museums Victoria during the voyage. Records include species identification, counts and/or weights, and are linked to sampling metadata such as station number, location (latitude and longitude), depth, time, and gear type. These data provide a baseline for assessing species composition, abundance, and distribution, supporting long-term monitoring, research, and management of the southeast Australian marine ecosystem.
