Tracking of marine animals by satellite

Abstract

Systems developed for tracking marine animals including fish, reptiles, mammals and birds using the.ARGOS system are described. Platform Terminal Transmitters (PTTs) attachable to animals now weigh less than 150 g and can be used on larger species of birds. Simultaneous remote sensing and location of animals using the NOAA satellites is described. Marine animals can only be tracked if they surface during a satellite overpass. New developments which permit animal location using fewer messages greatly increase the probability of successful tracking. Only satellite tracking can provide long-term ocean-wide coverage necessary for management and conservation of many important species.
