Satellite tracking and diving behaviour of sub-adult narwhals (Monodon monoceros) in Svalbard, Norway
Three juvenile narwhals captured during August 1998 in the northeast of Svalbard, Norway, were equipped with satellite-relayed data loggers (SRDLs) that transmitted diving and swim-speed data, in addition to location, for up to 46 days. A total of 1,354 complete dive cycles were recorded. Most of th...
