Tracks of two harbour porpoises obtained from satellite telemetry between August and November 1997. Both animals were tagged and released from herring traps around Grand Manan, New Brunswick. Only the best position from each day is shown. These positions were selected based on an analysis that examined both the location class and other diagnostic information provided by Service Argos. ■ = PTT97-03,▲ = PTT97-04.
