Photo & Video Log
This page contains photos and videos taken during the Bonaire 2008: Exploring Coral Reef Sustainability with New Technologies exploration from January 7 to 30, 2008. The Bonaire, Netherlands Antilles, is arguably the most pristine coral reef environment in the Caribbean. Click on any image to view a larger version and for additional information.

Bonaire island leaders and Bonaire's marine park manager listen as some of the preliminary findings from surveys are explained.
Dr. Patterson contracted the disease Dengue fever, a viral illness transmitted by mosquitoes.
After a great day of testing both Gavia AUVs, they are loaded into the back of a pickup truck to head back to “science headquarters.”

The animals encountered on the island are very different from those we encounter while at sea on a ship. (HR)
Another animal not commonly encountered. Pink flamingos are very common and inhabit saline ponds on the island of Bonaire. (HR)
Preparing to conduct underwater video transects, scientists enter the water from a platform at Oil Slick Leap dive site. (HR)
Elkhorn coral, once prevalent around the island's leeward coast, can only be found in a few areas and then in only small patches. (HR)
Keeping the surface float GPS line taut is essential for accurate positioning for video transects. (HR)
Millepora complanata, known as fire coral, is frequently found in the waters close to the shore surrounding Bonaire. (HR)
Preparing to launch, scientists attach the nose of the Fetch AUV which contains the side scan sonar, some water quality sensors, and the color video camera. (HR)
Bernard, Daniel, Mark, and Ken launch the Fetch AUV off the beach at the Invisibles dive site. (HR)
Fetch and Gavia AUVs simultaneously conducting survey missions at the Invisibles dive site. (HR)
The University of Delaware Study Abroad group stopping at the lighthouse (on the south end of the island) during an educational tour of Bonaire. (HR)
One of the study abroad students, Nate Maier, free diving at a dive site on the south end of Bonaire. (HR)
Elkhorn coral, is found in coral reefs throughout the Caribbean and in southern Florida. (HR)
Several members of the scientific dive team enter the water navigating by GPS along a predetermined heading and conducting video transects to determine percent coral cover. (HR)
Staghorn coral has been greatly reduced in abundance, most likely the result of several hurricanes passing through the region. (HR)
Much of the healthy coral cover recorded in the 1980s has been reduced to coral rubble and sand by Hurricane Lenny, which impacted the island in 1999. (HR)
Example of a high-resolution side-scan sonar mosaic created from survey data collected by the GeoSwath sonar on the Gavia AUV. (HR)
Scientists look for patterns of the oxygen concentrations over the reef, which provides an indicator of the health and productivity of the coral system. (HR)
Scuba divers are performing a photo transect survey of the Nukove sea floor down to depth of 40 meters. (HR)
The bathymetric sonar onboard the Gavia AUV provides an incredibly dense map of the reef structure including the overhanging coral on the crest of the reef. (HR)
Carried over the reef on the water surface, the BOA array of temperature sensors was deployed in 170 feet of water at Nukove. (HR)
The data loggers collect and record the temperature data from the BOA array and are connected to a float that maintains the upward position of the array. (HR)
Daniel is a recent inductee in the Explorers Club of New York and is carrying one of their flags that has been on expeditions since 1934. (HR)
Members of the science party load the Green Flash dive boat with the two Gavia AUVs and dive tanks. (HR)
Floating gently just below the surface with only the communications tower above the surface, the Gavia AUV awaits another mission command. (HR)
Student Explorers from the University of Delaware gather dockside for an impromptu lecture by Art, introducing the many features and capabilities of the Gavia AUV. (HR)
Student assistants from the University of Delaware Study Abroad Program help carry the Gavia AUV to the beach for a launch. (HR)
