Instrumentation for and Indices of Marine Mammal Responses to Low Frequency Sound

摘要

Our objective was to develop instrumentation capable of remotely monitoringbehavioral and physiological variables from marine mammals. A stomach temperature telemeter (STT) which transmits to a receiver in the animal mounted data logger was developed for recording prey ingestion events. A heart beat detector/telemeter and receiving module was developed and found to be suitable for recording heart rate from northern elephant seals, California and Steller sea lions, and harbor porpoise. We developed and successfully tested at sea a device for the remote release and retrieval of data loggers.
