Progress Code: completed Statement: See the report for further details on individual projects. 1987/88 Field Season at Heard Island. Harry R. Burton. Field Leader, Antarctic Division. The 1987/88 ANARE to Heard Island was the last of a series of three summer programs there (1985 and 1986/87); and with five and a half months on the Island. It was also the longest. Earth science had been the primary focus of the 1986/87 program. In 1987/88 the focus of the work was again biology, as it had been in 1985; and island transport (other than pedestrian) was by LARC. Nella Dan delivered the party of 17 from September 18 to 20 1987, with four at Spit Bay and the remainder at Atlas Cove. About a month later, on October 18 and 19 she returned: four of the party left and there were two new arrivals, so that 15 people were on the Island until Lady Franklin picked up the party and left on March 2 1988. A major task of the Expedition was to carry out a complete census of Heard Island's breeding population of Southern Elephant Seals. This task was done in the middle of October, when the numbers of cows hauled out to pup on the beaches were at a maximum and counts made at that time were sensibly referable to other years and other islands. It was the first total census ever completed on Heard Island although one made in 1985 was nearly so. The party was able to walk to Long Beach and census that area. and the availab1l1ty of a helicopter for two days allowed the total photographic coverage of Spit Island, a sedimentary island little more than a metre above sea level and about a kilometre to the east. This island is home to several thousand seals. The one photographic run over this island on October 18 produced a 70mm film record. and thus the whole Island census was completed. Although strong winds during the photography prevented complete overlap of all the aerial photographs. allowance for the small proportion of missed ground was made in censusing. The final total for Spit Island was 3,200 plus or minus 150 cows. A number ...
