Scuba Diver Accessand Stressed Reef Ecosystemsin the Florida Keys National Marine Sanctuary David M. Lawrence
The problem • As the popularity of scuba diving has grown, researchers have documented increasing damage to dive sites by inexperienced and careless divers and dive operators. • Causes of damage include: • Boat anchoring and grounding • Incidental diver contact with reef • Lost or poorly secured gear • Diver-induced damage exacerbates other problems affecting coral reefs.
Possible solution: Site closure • Site closure • Eliminates damage by divers and dive operators • Problems: • Equity • Fair distribution of resources • Economy • Scuba diving generates millions of dollars in revenue and supports hundreds of jobs in Monroe County, Fla. • Education • Loss of public connection with reef ecosystems • Loss of public support for conservation efforts
Possible solution: Limit access • Limit access via a permitting or lottery system • Reduces odds of damage by divers or dive operators • Problems: • Equity and Economy (blend together) • Lack of permits or lottery assignments may drive safe, high quality dive operations out of business. • Unfair competition (or lack thereof) between commercial and private boats • Prospective divers may be forced to choose between diving with unsafe or substandard operators or not diving at all
Proposed policy: Certification • I propose a voluntary program certifying that dive operators engage in best practices as well as encourage the divers they host to engage in best practices.
Pre-dive briefings • Emphasize diver skills in pre-dive briefings • Buoyancy control • Proper trim • Properly secured gear
Vigorous supervision • Have adequate number of divemasters observing divers in water • Encourage divemasters to redirect problem divers to less vulnerable portions of a dive site.
Quality gear • Provide divers with up-to-date, quality gear • Weight-integrated BCDs • Combined low-pressure inflators/alternate air sources • Retractors for hoses, lights, etc.
Policy problems and benefits • Problems • May increase cost for some dive consumers • May increase cost for dive operators forced to hire more divemasters or upgrade rental gear • Benefits • Preserves diver access to sites • Promotes economy • Promotes education and environmental awareness • Improved dive experience
