Measuring heart rate to assess the stress response in large whales
Abstract
The proposed research will develop and implement the technology needed to measure heart rate of large, free-ranging whales in order to assess the stress response associated with anthropogenic stimuli and acoustic disturbrance. Specifically, we will systematically and experimentally test different tag and sensor designs to optimize digital electrocardiogram (dECG) signals. We will explore multiple combinations of suction cup and electrode size, as well as the material properties of the suction cup, all of which predictable influence dECG signals. Different tag designs will be tested on large whales in the open ocean and resultant dECG signals will be analyzed in a comparative context. These data will enhance the technological approaches available to monitor the baseline physiological processes of large whales and the changes in cardiac physiology that occur from anthropogenic disturbance.
