A second major theme is that of physiology, behavioral ecology and population structure. The ability to apply instruments to animals and actively record physiological parameters such as body temperature, oxygen utilization or heart rate has provided important net knowledge about how animals function in the wild. This collection includes papers on Weddell seals in eastern Antarctica, harbor seals, Mediterranean monk seals and Stellar sea lions in the northern Gulf of Alaska. There is also the first biologging study of Blainville's beaked whales around Hawaii, where they are sometimes exposed to sonar from naval vessels.
The third theme focuses on the ability of a tagged animal to record useful data about its surrounding environments sometimes referred to as, "Animals as ocean sensors." Elephant seals, for example, can sample the water column up to 60 times per day, reaching depths of 1000 m or more under their own power, across broad expanses of the ocean that are difficult to reach by ship or other conventional means. Such data are now being incorporated into global ocean databases, and are being used by the oceanographic community to better understand ocean circulation. Specific studies in the collection focus on the data from northern elephant seals, juvenile Stellar sea lions, olive ridley sea turtles and Atlantic bluefin tuna.
The fourth theme is the use of biologging science for the conservation of threatened and endangered species. By providing a detailed understanding of how animals utilize th
