A new way to look at mesoscale zooplankton distribution: An application at the Antartic Polar Front
During the austral summer of 1996 an intensive multidisciplinary survey was carried out in the Antarctic Polar Front. In this paper, we examine the relationship between hydrographic features and the acoustic backscatter signal from a vessel-mounted acoustic Doppler current profiler. We introduce two...
