Joint Polish/American hydroacoustic survey of Elephant Island and the vicinity of King George Island, 1988
The hydroacoustic survey found a low krill abundance in most areas covered by last year’s survey. The total biomass in the vicinity of Elephant Island was estimated from 120 kHz data to be 260k tonnes and that in the Bransfield Strait south of King George Island was 39k tonnes for a total of 299k tonnes in the combined areas. The estimated 200 kHz survey data were higher, giving 715k tonnes near Elephant Island and 83k tonnes in the Bransfield Strait. The survey results apply to 7 453 n miles2 near Elephant Island and 2 894 n miles2 in the Bransfield Strait. The full survey found (120 kHz data) 385k tonnes (in 7 787 n miles2) in the Bransfield Strait and the area north of King George Island and 309k tonnes (in 8 836 n m2) in the expanded area around Elephant Island.
