ADBEX2 - Antarctic Division BIOMASS Experiment II

Nella Dan left Hobart with a full complement of passengers including 4 members of Davis 1984, 6 members of Davis summer 1983-84, 21 Mawson 1984 and 3 Mawson summer 1983-84, 18 scientists and support staff for the ABDEX-II program, general cargo for Mawson and a small amount of priority cargo for Davis. A meteorological buoy was launched at 53d 25.6'S 132d 44.0'E on 7 Jan. The marine biology program began on 14 Jan at 63dS 73dE and continued along 73dE. However, after 10 hours bad weather forced a suspension. The Davis ice edge, just to the north of the anchorage, was reached on the afternoon of 15 Jan. Personnel and cargo were discharged by LARC and barge, operating to the south of Gardner Island. The ship sailed soon after midnight. The marine program was resumed later that day. Five stations were taken along the track to 65dS 73dE. At 66d30'S 60dE a sampling station was taken. Further stations were taken at 66d30'S 59dE and 66d08'S 57d46'E. The latter station was within the pack-ice. A transect was then run north along 58dE to 63dS and then down 60dE to 66dS. Finally on 23 Januray four stations were taken from there on a direct line to Mawson. Total station time was two days ten hours, additional steaming time four days five hours, and hove-to one day six hours. The remaining time was taken up with normal steaming. Sampling included 24 CTD casts, 22 bongo hauls, 18 RMT and 2 beam trawls. At all CTD stations water was collected for salinity, oxygen and nutrient analysis. Bongo hauls were made for krill larvae and RMT hauls for krill for ageing. Reproductive studies for investigations of bioluminescence metabolic studies were made on animals collected by drift nets. On 24 Jan Nella Dan arrived at the edge of the pack-ice about 10 km from Mawson, reaching the harbour on 1 Feb. Despite the large amount of broken ice, unloading was done using the barge Fred Bond assisted by LARCs. Change-over of the station was completed and the ship left on 4 Feb, berthing at Hobart on 16 Feb - about 8 days later than scheduled. Source: Antarctic Division Annual Review 1983-84
