Coffin's Patch: Sabrina and Ashleigh

On June 10, 2015 we took the KML research boat out to the Coffin's Patch SPA (special protection area) 5 miles off the oceanside shore of Key Colony Beach, FL, to record qualitative data of the biodiversity in the coral reef. The area we anchored at had a depth of approximately 8-15 feet, with crystal clear waters and a wind-driven, light current. Clouds dominated the skies, resulting in minimal  amounts of light penetrating the water's surface that cooled the overall temperature. Below the surface, 4-5% coral coverage was seen on a sandy bottom creating many habitats for a richly biodiverse ecosystem. Although we were in a natural habitat, there were many anthropogenic influences. Among these influences, there were a number of other boats, snorkelers, fishermen, and a fallen lighthouse. However, not all of these factors were negative to the coral reef. The lighthouse provided an artificial substrate that provided a habitat to high populations of species, including fire coral and stoplight parrotfish. Abundant amounts of algae beds and seagrasses propagated homes and subsidence to a heterogenous mix of fish species. The most prolific populations we came across included four-eyed butterflyfish, gray angelfish, stoplight parrotfish, and sergeant majors. However, rare encounters with green moray eels, yellow stingrays, and hawkbill sea turtles were also noted.

Compared to the several other sites we were exposed to, this specific ecosystem was by far one of the most diverse and flourished. It is obvious as to why these reefs are such a hotspot for snorkeling and diving. The high coral coverage and shallow waters allows for opportunities to truly observe the marine life on a detailed scale, as shown in the photo below. We feel very lucky to have had the opportunity to witness such a beautiful, natural environment.
