Tracking of marine mammals by satellite has long been recognized as one of the most important and promising techniques available for studies of cetacean movement and migration.


So far, it has been challenging to successfully deploy satellite transmitter tags on the large fast-swimming rorqual species, as they are too large to be captured alive and many of them too aversive to be approached at close distance. While long-lasting tag deployments have been achieved, similar tags that can be deployed from long distance have not yet been developed.
