Research institutes often lack funds and necessary manpower to perform large scale monitoring. For land environments it has been shown that citizens can be involved in research, by contributing significantly to the collection of data. Underwater research requires special operational skills and SCUBA certification, and it may be difficult to involve large numbers of volunteers. We show that, in a short time, thousands of recreational divers can be recruited for monitoring the marine biodiversity status. On a specially formulated questionnaire, volunteers reported the presence of 61 marine taxa encountered during recreational dives. During the 4-year study, 3825 divers have completed 18,757 questionnaires, corresponding to 13,539 diving hours. The volunteer sightings-based index showed that in the monitored area the environmental quality did not change significantly on the time scale, but it had a significant correlation with latitude, suggesting improvement in the southernmost areas. This condition could be related to the main presence of stressors in the northern areas, and has been corroborated by professional investigations. Our experience shows that recreational divers can collect a considerable amount of data, over a vast geographical area, thus decreasing the costs for research institutes. The greatest drawback with this collaboration is the difficulty to obtain sampling distributed uniformly in space. Projects that invite citizens to get involved in ecological research provide members of the community of every age valuable opportunities to improve their science literacy and environmental awareness. This research, patronaged by the Italian Ministry of the Environment, was supported by the ASTOI-Association of Italian Tour Operators, the Association of Diving agencies operating in Italy (IDEA, PADI, PSS, SNSI, SSI) and the popular scientific magazine Quark. 16-40 Auvs Explore Reef Sustainability Noelle RELLES* 1 , Mark PATTERSON 1 1 Biological Sciences, VIMS, Gloucester Point, VA The reefs surrounding the island of Bonaire are the most pristine in the Caribbean, with high percent coral cover (40-60%) and low abundance of macroalgae. The Bonaire National Marine Park sets an important precedent regarding marine protection policy and was nominated for United Nations World Heritage in 2004 due to the high number of endemic marine species. However, surveys of Bonaire’s underwater biota have been few, particularly of the deeper reef (65-170 m depth). In 1985, Dr. Fleur van Duyl completed an underwater atlas of Bonaire, mapping the bottom type and benthic community to a depth of 10-12 m. During a 5 week NOAA signature expedition in 2008, the reefs were remapped using a combination of 3 Autonomous Underwater Vehicles (AUV) for survey, and Nitrox and Trimix SCUBA diving. The twilight zone of the reef was investigated using high frequency side scan sonar, multibeam sonar, video, and water quality sensors that were fixed to the AUVs. AUV technology was utilized in this project due to its cost effectiveness, and capability for deeper surveying and greater coverage over shorter time periods than previous mapping efforts. Divers using Nitrox and Trimix SCUBA served to groundtruth data collected by AUV missions at several points on the reef. At select locations, the resulting data were compared to van Duyl's snapshot from the 1980s. The resulting maps are maintained in ArcGIS, with kmz layers available for use by coral reef scientists, managers, and the public using Google Earth. The resulting maps are compared to the previous work by van Duyl (1985) and more recent work by Bak et al. (2005) and used to assess the success of Bonaire’s experiment in Marine Protected Areas. 16-42 Shallow And Deep-Water Gorgonian Surveys on Saba Bank, Netherlands Antilles Peter ETNOYER* 1 , Herman WIRSHING 2 , Juan Armando SANCHEZ 3 1 Harte Research Institute, Texas A&M University, Corpus Christi, TX, 2 Marine Biology and Fisheries, Rosenstiel School of Marine and Atmospheric Science, University of Miami, Miami, FL, 3 Departamento Ciencias Biológicas, Universidad de los Andes, Santa Fe de Bogota D.C, Colombia Saba Bank is a large submerged platform (~2200 km2) mostly within scuba diver depth range (< 50 m), located 4 km southwest of Saba Island in Netherlands Antilles, Caribbean Sea. Ships traveling to and from oil terminals on nearby St. Eustatius occasionally anchor on the Bank, damaging benthic megafauna. Concerns about the practice prompted a recent series of investigations. Gorgonian corals are among the most common and conspicuous benthic megafauna in local shallow and deep-water (> 50 m) environments, so we sought to characterize gorgonian habitats and estimate species richness using a combination of remote sensing, scuba diving transects, and a Seabotix LBV200L remotely operated vehicle (ROV) for deeper collections. Landsat imagery and multibeam bathymetry were employed to create a block design with random survey sites. A total of 14 scuba dives and 5 ROV dives were completed in 10 days. During that time, 47 species were collected down to 130 m depth, including undescribed species in the genera Pterogorgia and Lytreia. Two different shallowwater gorgonian habitat types were identified by multidimensional scaling and hierarchical cluster analyses of species density values: 1) a higher diversity, higher density ‘reef crest’ environment characterized by Eunicea spp., Gorgonia spp., and Pseudopterogorgia spp. and 2) a lower diversity, lower density ‘reef flat’ environment predominantly composed of Pseudopterogorgia acerosa, Pterogorgia guadalupensis, and G. mariae. These analyses support hypotheses of habitat similarity within zones, and a gradient in diversity and abundance from the reef crest to the reef flats. Some degree of heterogeneity in gorgonian assemblages occurred along the 40 km southeast rim of Saba Bank. Our discoveries of two undescribed gorgonian species argue strongly that continued scientific exploration of Saba Bank is necessary. 16-43 Crustaceans Of Saba Bank, Netherlands Antilles Morgan KILGOUR* 1 , Thomas SHIRLEY 2 1 Texas A&M University- Corpus Christi, Harte Research Institute, Corpus Christi, TX, 2 Texas A&M University-Corpus Christi, Harte Research Institute, Corpus Christi, TX Saba Bank is a large (~2200 km 2 ) submerged atoll approximately 4 km west of Saba Island in the Netherlands Antilles whose crustacean fauna is poorly known. Concerns about anchor damage from oil tankers to coral habitats on the Bank prompted a study to characterize its fauna. We focused on the decapod crustaceans and used three methods to collect samples. Random collection sites were sampled within habitat types (fore reef, reef flat, back reef slope, lagoon, patch reef and atoll slope) delineated from Landsat imagery and high-resolution multibeam bathymetry data. Scuba (14 dives) was used to observe, photograph, and collect decapod specimens and also to collect sponges, small corals, gorgonians and other biogenic habitats containing cryptic and saxicolous crustaceans. A Seabotix ROV (Remotely Operated Vehicle) was used for 5 days to collect gorgonians, sponges and other biogenic debris containing crustaceans, below diver depths to 130 m. Two crab traps, each fitted with smaller shrimp traps, were baited with multiple kinds of bait and set for three 24 h periods in 300 to 400 m depths to collect specimens below ROV and scuba depths. Crustaceans collected with scuba were differentiated by depth, habitat, and reef zone; depth and location were recorded for specimens collected with the ROV or traps. More than 95 crustaceans were collected, with many representing range extensions or rare species. Assemblage composition and species richness were heterogeneous among habitats, and many species had pronounced depth distributions. Species accrual rates imply that only a portion of the decapod fauna has been sampled; additional quantitative sampling is warranted to complete an inventory of the decapod community and more fully describe their assemblage patterns. 138
