Antarctic krill swarms in Scotia Sea Summer 2003
The dataset contains 2043 krill swarms detected using an EK60 echosounder during transects of the Scotia Sea during Jan and Feb 2003. Each of the swarms was detected using the dB difference method described in Tarling et al. 2009. Corresponding measurements of the vertical velocity within and above...
