Temporal and spatial variation of plankton abundance in the Gulf of Carpentaria, Australia 1975-1977
The Gulf of Carpentaria is a large ( ca . 3.7 × 105 km2) shallow (<70 m) embayment in tropical northern Australia lying between 11 and 17.5°S latitude. Although it contains a multi-species penaeid prawn fishery which is Australia's largest and most valuable fishery its hydrology and planktol...

The Gulf of Carpentaria is a large ( ca . 3.7 × 105 km2) shallow (<70 m) embayment in tropical northern Australia lying between 11 and 17.5°S latitude. Although it contains a multi-species penaeid prawn fishery which is Australia's largest and most valuable fishery its hydrology and planktology are largely unknown. As a background to a study of the larval ecology of penaeid stocks, ten Gulf-wide survey cruises, sampling the plankton and hydrography, were undertaken over a twenty month period from August 1975 to May 1977. Though comparisons with other studies are difficult because of variations in sampling techniques and biomass estimation methods, the plankton biomass in the Gulf of Carpentaria appears to be high by comparison with other areas around Australia.
