| Summary: | 62 routine sampling sites were taken within the area 67 degrees to 78 degrees East, 65 degrees South to the Antarctic coastline, in a grid arrangement with approximately 30 nautical miles in latitude and longitude between sites. At each site the 0-200m water layer was sampled by a downward oblique haul with a rectangular midwater trawl RMT 1+8 net. Ten horizontal tows were also made with the RMT 1+8 to identify krill/zooplankton targets detected by the echosounders. A Hardy continuous plankton recorder (CPR) was also deployed to continuously collect zooplankton and krill in the upper 20m. A total of 1200 miles were sampled with the CPR. Please see the reference given above for further details. As no evidence to the contrary has been established, it is concluded that this dataset is logically consistent. This dataset contains results from the Aurora Australis Voyage 6 1990-91. Surveys of krill and other zooplankton were taken in Prydz Bay, Antarctica between January and February 1991. Species identity and abundance data, length, age, growth rate and mortality rate data were obtained. The major species investigated were Euphausia superba, Euphausia frigidia, Euphausia crystallorophias and Thysanoessa macrura. Other pteropods and cephalopods were also studied. This dataset is a subset of the full cruise. |
