Acoustic measurement of cardiac function on northern elephant seals
A self‐contained acoustic recording tag has obtained signatures of heartbeat from both captive and free‐ranging northern elephant seals (Mirounga angustirostris). Simultaneous electrocardiogram (ECG) and acoustic signatures obtained from the submerged captive seal confirm that seal heartbeat can be...
