Collection, processing and potential use of sonar data from krill fishing vessels
Antarctic krill distribution, and potentially abundance. Data from sonars can be used independently of ... acoustic surveys. Sonars are capable of sampling large volumes of water and can image entire krill swarms ... and track changes in swarms through time. Some commercial krill fishing vessels, e.g. ‘Juvel’ and ... vessels. The purpose of this paper is to stimulate discussion on the utility of sonars to describe krill ...
