USGS conducts ground-penetrating radar survey to map peat
USGS recently tested ground-penetrating radar (GPR) on a drone for mapping peat thickness and extent. This work is part of a collaboration with Florida Atlantic University to study and locate large carbon gas emissions from peat soils in the swampy wetlands of the Everglades in Florida. The study is exploring the use of airborne GPR to map gas accumulations in the peat through repeat measurements with a drone over time and is funded by the U.S. Department of Energy.
