Kite-cameras track eroding dunes

Along the coast of the Carolinas, cameras attached to kites are collecting aerial images of protective barrier dunes in order to observe how they are changing over time, Sierra Magazine reports.

Why it matters: Barrier dunes buffer beaches from storm destruction. Elsemarie DeVries, who leads a team of researchers at the University of North Carolina at Chapel Hill carrying out the study, told Sierra her primary concern is that rising ocean tides and powerful storms threaten dune ecosystems that don't have enough time to rebuild themselves between storms.
