  • RV Mt. Mitchell Advances Science Through Ocean Mapping

    Oceans cover 71 percent of the Earth’s surface and contain 97 percent of the planet’s water, yet more than 95 percent of the underwater world remains unexplored.

    One tool that will help map these unexplored reaches is the multibeam echosounder.

  • Waitt Institute Completes Pacific Survey Utilizing AUV Technology

    In the fall of 2008, the Waitt Institute for Discovery took possession of two Hydroid Inc. (Pocasset, Massachusetts) REMUS 6000 autonomous underwater vehicles (AUVs) and began a collaboration with Woods Hole Oceanographic Institution (WHOI) and Harbor Branch Oceanographic Institute (HBOI) at Florida Atlantic University.

  • A Platform for Underwater Cartography Tool Development

    The practice of cartography has evolved through the technological development of tools that allow for the collection of spatial or spatially correlated data sets. Improvements in instrumentation, from the groma to the theodolite to the cross staff to the global positioning system, have enabled the generation of more accurate and precise maps.

  • Pipeline Inspection With Interferometric SAS

    Traditional sensors for pipeline inspection are side scan sonar, multibeam echosounders and video cameras. These sensors require different geometries, meaning that several passes must be made in order to get a complete data set.

COVER
A pair of endemic Red Sea bannerfish among fire coral, branching finger coral, Goniastrea edwardsi, massive Porites, Favia stelligera, Pocillopora verrucosa, dark blue Stylaster, Xenia and blue-green chromis fish, photographed during the Living Oceans Foundation’s 2009 expedition to the Farasan Banks in the Red Sea, which collected data on reefs that had not been scientifically surveyed since Jacques Cousteau visited the area in the 1950s.

AUGUST FEATURED ARTICLES


APPLICATION OF SIDE SCAN SONAR FOR THE DETECTION OF DERELICT FISHING GEAR
Jeffrey June, Abby Faust (Natural Resources Consultants Inc.) and Crayton Fenn (Fenn Enterprises Inc.) describe a program that uses underwater imaging equipment and survey strategies to find and remove derelict fishing gear in the Puget Sound.

GIS DATA PORTAL ENABLES ECOSYSTEM-BASED MANAGEMENT
Katie Budreski (Stone Environmental) and Karen Richardson (ESRI) explain how a Web-based geographic information system is providing management of more than 400 datasets on New York state shorelines.

SEABED MAPPING FOR MARINE PROTECTED AREA PLANNING AND MONITORING
Dr. Peter Davies, Dr. Alan Jordan and Edwina Mesley (New South Wales Department of Environment, Climate Change and Water) detail an interferometric swath system and towed video sled that provide vital scientific data for sustainable marine management.
