Title: Impact of recreational divers on coral reefs in the Florida Keys
Author: Talge, H
Abstract: Recreational divers were systematically observed in the Florida Keys between May 10 andAugust 13, 1989. A total of206 divers were observed during 66.6 hours of diving. Divers wearing gloves were responsible for 72% of the 1164 interactions observed. Out of the 135 scuba divers, 26% had one or less interactions with corals; 10% had 11 to 20 interactions; and4%had 30 or more interactions per 30 minutes of diving time. Of the 71 snorkelers, 61%had one or less interactions with corals and none had more than 5 incidents. However, snorkelers treading water stir up large clouds of sediments and are more apt to stand on corals than scuba divers. Wilcoxon Two-Sample Tests show that divers with gloves have significantly higher numbers of interactions with corals than divers without gloves, that men have more interactions than women, and that scuba divers have more interactions than snorkelers.
