Building a cost effective time-depth recorder to track fine-scale penguin Foraging Behavior
We developed our own animal-worn datalogging tags that measure the fine-scale diving behavior of marine predators. Datalogging tags are an integral tool to studying marine predator diving behavior because they allows us to document animals where we are unable to follow them on their foraging trips. These tags measure an animal's precise location, fine-scale movement and acceleration, temperature of the water, and the depth the animal dive (down to 1000 meters). These tags will be used to document emperor penguin diving behavior and track their movements while they forage at-sea. Emperor penguins are known to dive to great depths (564 meters) and for long durations (>27 minutes) in search of prey. Once the penguins return to the colony to feed their chick we will remove the tag and download the data from their journeys.
Datalogging tags can be purchased however they are very expensive and can be a barrier for many students and researchers. In collaboration with Dr. Birgitte McDonald, Katie Harrington, James Fahlbusch, and Parker Forman we developed a cost-effective and open source datalogging tag that is one third of the cost of current tags on the market. This open source datalogging technology will put high resolution, low cost, and customizable tags in the hands of more researchers.
