The observations were taken from the Heard Island area in January and February 1992. The data contains temperature and salinity data from a CTD survey and the results from demersal fish trawl surveys.

The major species were Dissostichjus eleginoides, Channichthys rhinoceratus, Channichthys gunnari, Lepidonotothen squamifrons, Gymnoscopelus nicholsi and Paradiplospinus gracilis. This is a subset of the data for the whole voyage.

Statement: These data follow on from that of the 1990 winter cruise (HIMS). Sampling was carried out using a 35m headline length bottom trawl. Stations were chosen using a random stratified survey design, stratified according to depth: 0-100m, 100-200m, 200-300m, 300-500m. Sixty-nine trawls were completed successfully.

All fish were identified, weighed and measured on board, except specimens too small to weigh accurately, which were frozen for later weighing in the Antarctic Division laboratories. For all common species, guts, gonads and otoliths were removed from 25 specimens of each species per haul (if numbers permitted). For large catches of individual species, a random subsample of 50 was individually weighed, measured and guts gonads and otoliths removed, a further 50 were weighed and measured, and a further 100 were measured. The total number and weight of each species was also recorded.

At some sites, samples of liver, heart and muscle of Dissostichus eleginoides were taken and stored in liquid nitrogen for the mitochondrial DNA (mtDNA) study.

CTD data were collected at most stations, so fish data and oceanography data are consistent. Position, date and time of each station was recorded, and tabulated results, a cruise track, and a station map is included in the reference given above.
