Experts Explore the Edges

Daniel P. ZitterbartAssistant Scientist, Applied Ocean Physics and EngineeringIn my group, we use remote sensing of animal behavior to understand more about ocean and ecosystem health. We are continuously monitoring several penguin colonies around Antarctica and the sub-Antarctic islands. One way that emperor penguins cope with the extreme climate is by huddling together for warmth. This provides a way to estimate the average energy/fat reserves of the colony, the equivalent of weighing 25,000 penguins, without ruffling a feather. Tracking energy reserves of such a penguin colony over time helps us to better understand the health of the species as well as the food resources in the ocean, a proxy for ocean health.
