World’s lakes may be much shallower than previously thought

The world’s lakes are only about two-thirds as deep, on average, as previously thought according to a mathematical analysis presented by Follows Group graduate student B. B. Cael at a meeting of the American Physical Society this week.

If correct, Cael's finding could help climate scientists more accurately model global climate change, as shallower lakes generate more heat-trapping methane gas.

B. B. Cael is a PhD candidate in the MIT-WHOI Joint Program in Physical Oceanography.

Cael says of his work, "I think about the Earth. In particular, I think about relationships and patterns between and within the complex assemblages we call the ocean, the climate, and the biosphere. In particular particular, I think about how we can utilize mathematical tools to construct better understandings of their ways."
