Peeking at Peatlands: Satellite Data Fuel New Findings

by Adityarup Chakravorty 15 June 202229 June 2022

Researchers are combining hard-to-get field measurements with satellite imagery to gain new insight into where peatlands are and how they work.

In the foreground sits a yellow-beige pond, with tree trunks scattered about its surface. Two dredges that appear to be made of wood float by the banks, smoke rising from between them. In the background, the green rain forest towers, the blue sky smudged with white smoke.
