Tracking Kuril harbor seals (Phoca vitulina stejnegeri) at Cape Erimo using a new mobile phone telemetry system
We developed a tracking unit that uses the Japanese mobile phone network to transmit data from Kuril harbor seals (Phoca vitulina stejnegeri), which are difficult to recapture. The unit senses location by GPS, hauling-out status, depth and temperature. Six wild Kuril harbor seal pups were tracked at...
