ABSTRACT Time series of acoustic observations with three frequencies were made on Antarctic krill (Euphausia superba) near Elephant Island and in Bransfield Strait. Local changes of biomass were ten-fold over 2-3 days. The total biomass in a very large swarm near Elephant Island was 2.1 million metric tons distributed over 450 km2. The abundance in the swarm was 200–-500 g/m3 over a vertical extent from 10-240 m. Smaller patches were 40-150 g/m3 and often associated with the 100-150 m bottom contour. Assessing the distribution and abundance of very large swarms presents problems beyond those of routine acoustic surveys.
