Biofilms are mats of microorganisms that stick together and form a layer, or “film,” on and within objects in the water—including ships—which could represent one possible mechanism for the spread of microbes (and potentially SCTLD’s unknown causative agent) from one region to another. To test this theory, scientists at the St.

Radioactive isotopes are common in nature and emit particles that can be detected, quantified, and used to characterize environmental processes.

Barrier islands off the coast of northern Pinellas County, Florida including Anclote Key, Three Rooker Island, and the northern tip of Honeymoon Island. These barriers protect a highly populated coastline.

Two video cameras are mounted on a bluff above Marconi Beach, Cape Cod National Seashore, Wellfleet, MA. Every half hour during daylight hours, the video camera collects imagery for 10 minutes and processes it. This is the snapshot image, like a photo, taken at the beginning of the 10-minute window and looking northeast.

Mendenhall postdoctoral fellow Daniel Ciarletta captured this view of the modern beach ridge system at Caladesi Island, along the Gulf coast of central Florida. Ciarletta and colleagues are studying the island as part of a project to explore barrier island response to long-term changes in sediment availability.
