Method and Device for Internal Acoustic Monitoring of Marine Mammals

Abstract

The invention is a method directed towards measuring differences in sounds, temperatures and pressures detected within a marine mammal, then analyzing the data to better understand the activities and behavior of the marine mammal. Wherein a buoyant capsule having a hydrophone, a temperature sensor, a pressure sensor, a memory chip, a radio frequency (RF) generator (or other means to enable its detection), software and a battery enclosed within a shell is disposed into a body of water. After a marine mammal ingests the capsule, the capsule is activated after which pressure data and sound data is detected, including sonar transmitted by a monitoring ship. The data is saved on the memory chip for recovery.
