Review Genesis and evolution of bio-logging devices: 1963–2002
Abstract: Bio-logging devices have become an integral part of many studies on the behav-ior, physiology and ecology of marine vertebrates. In the beginning, 1963, a time depth recorder (TDR) was designed to measure time and depth of freely diving Weddell seals, Leptonychotes weddellii, in the Antarc...
