Diadema antillarum, the long-spined sea urchin, is an ecologically important species in Caribbean coral reef habitats where it controls algal growth and coverage and helps keep reef surfaces clear for corals to grow and settle. In early 2022, the remaining D. antillarum populations began experiencing mass mortality in the Caribbean.

Ground-Penetrating Radar instruments are towed across land. Data from this instrument show underlying sediment layers within the dune and barrier island, which may reveal patterns of growth and erosion.

A colony of the soft coral known as the "bent sea rod" stands bleached on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae – all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer.

We collect terrestrial (barrier island) and marine (nearshore and estuarine) sediment cores to ground-truth geophysical observations. These cores are used to understand the history of barrier island formation and erosion.
