Aurora Australis Voyage 7 (KROCK) 1992-93 Zooplankton Data
Progress Code: completed Statement: Only four of the scheduled sites were not sampled due to heavy pack ice cover (9-10/10), in the areas of Four Ladies Bank and Cape Darnley. Sections of the study areas were previously sampled for zooplankton in 1990/91, and hydroacoustic data were also previously...

Sections of the study areas were previously sampled for zooplankton in 1990/91, and hydroacoustic data were also previously sampled in 1990/91 and 1991/92. A minimum of 88 stations were planned, approximately 30 nautical miles apart in latitude and longitude. Sites between 67 and 78 degrees East were also sampled during 1990/91. The 0-200m water layer was routinely sampled at each station by a downward oblique haul using a rectangular midwater trawl (RMT) 1+8 net. CTD or bottle casts were made to 200m normally, to sample phytoplankton and record physical oceanographic profiles. Hydroacoustic data were obtained using echosounders and echointegrators operating at 38kHz, 120kHz and 200kHz. Hydroacoustic data were also collected during 1990/91 and 1991/92.
