This dataset contains results from the Antarctic Division Biomass Experiment (ADBEX I) cruise of the Nella Dan. This cruise is the second in a series of six cruises, and follows the First International BIOMASS Experiment (FIBEX) in early 1981, documentation of which can be found in ANARE Research Notes 7, or by searching the metadata records for FIBEX. ADBEX I operated between November and December 1982, and studied the distribution and abundance of krill (Euphausia superba). Surveys of krill and other zooplankton were taken off Antarctica in the Australian sector (Mawson to Davis region) and Prydz Bay. The major species investigated were Euphausia superba, Euphausia frigidia, Euphausia crystallorophias and Thysanoessa marcuria. Other pteropods and cephalopods were also studied. Physical and chemical oceanography data were also obtained at some stations, as well as phytoplankton samples. Summary results are listed in the documentation.

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, phosphate, silicate) data obtained from the Antarctic Division BIOMASS Experiment I (ADBEX I) cruise of the Nella Dan, during Nov - Dec 1982. This cruise is the second in a series of six, conducting a long term field survey of krill and other zooplankton. 79 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 28 out of the 79 CTD stations. Casts within the shelf zone were made to the bottom and down to 2000 m offshore. Oceanographic sampling was subordinate to other programs such as the phytoplankton survey, hence the locations of the CTD stations were not always ideal for oceanographic purposes. Nutrient samples were collected to provide information for the interpretation of phytoplankton distribution and abundance.
