AMLR Acoustics Data 1996-2011 v1.1

Metadata Updated: March 1, 2024

Calibrated, integrated, and averaged acoustics data, including estimates of krill (Euphausia superba) biomass density, collected around Elephant Island, the South Shetland Islands, and the Antarctic Peninsula by the U.S. AMLR Program. Data are integrated over depths from about 10-15m down to the bottom or 250m (whichever is shallower) and averaged over 1-nmi intervals.
