Pulley Ridge - The First Scientific Dive On Pulley Ridge

The First Scientific Dive On Pulley Ridge

The first scientific dive on Pulley Ridge was led by James K. Culter of the Mote Marin Laboratory in Sarasota, Florida and included over 40 team members. The trip went from 23 June through 1 July 2005. The aim of this mission was to collect primary data and biological samples and to document marine life through still photographs and video The expedition was done at depths ranging from 200 to 260 feet. “…very few scientific reef investigations are conducted within the depth zone between traditional scuba air limits of 130 feet and deep-sea submersible research at and below 500 feet”.

After the expedition, Culter made some observations. He noticed some unusual neon colors in the reef. This bioluminescence may have some significance to the ridge. He also mentioned that compared to a shallow reef, there seemed to be fewer fish. Tilefish and groupers were seen at the ridge. He noted that this could have been because they were scared away by the divers or the fish could only come out at night. There appeared to be fewer crustaceans than one would normally see in a shallow reef, but there were several species of algae present.
