| Summary: | Abstract: Among a variety of remote observation systems for the study of marine crea-tures, data loggers emerged in the 1990’s, following mechanical depth recorders (TDRs). Digital data loggers have played a critical role in studies on marine animal behaviour, ecolo-gy and physiology. Today, this field is called bio-logging science. Digitalization has allowed further miniaturization of logger systems, which is particularly important to this science so that the effect of device attachment to animals is minimized. At the same time digital tech-niques have enabled us to develop multi-sensor loggers, which has enhanced integration of information on many aspects of marine animal lives. Using advanced systems we are now able to determine when feeding occurs during dives, elucidate stroking patterns, 3-dimen-sional dive paths and even prey distribution along the dive path. This article traces the histo-ry of development of both mechanical and digital loggers developed at and used by the researchers of the National Institute of Polar Research, Japan. key words: bio-logging science, data loggers, diving behavior, foraging behavior, three- |
