Record-high seawater temperatures and calm seas in the summer of 2005 led to the most severe coral bleaching (death) ever observed in the U.S. Virgin Islands.
By measuring the current and historical growth rates of coral skeletons, and using field experiments, we intend to find out whether rising atmospheric CO2 and rising sea levels will cause coral reefs to erode and cease to function.
Brief report on sidescan sonar data, sediment sampling, and submersible and video photography studies of destruction of deep-water coral pinnacles where fish spawn off east-central Florida in the Oculina Bank in order to restore and protect the habitat.
Report on problems in preserving coral reef ecosystems with links to information on the interagency U.S. Coral Reef Task Force, press releases, reports, and NOAA coral reef sites.
Overview of research in the Hawaiian Islands and Guam to gain insight into the structure of coral reefs, to provide the basis for future monitoring, and to understand the influences of natural processes and human activities on coral reef health.
Manual for research program on the nesting habits of sea turtles of the Virgin Islands, with descriptions of species, nesting behavior, observation methods, record keeping, tagging, and tissue sample collection. (PDF file, 121 pp.)
Report with mini-movie and photos on the hypothesis that the atmospheric transport of dust arising from the desertification in northern Africa led to algal infestation of corals, coral diseases, and the near extinction of associated sea urchins.
Shows how coral reef specimens are collected, the type of information gained from them, and the methods by which they are measured and studied to understand recent (past few centuries) changes in climate.
We conduct systematic imaging of reef habitats in order to provide regulatory agencies with information they need to decide whether those reefs should be designated as protected areas.
Plan for an upcoming study, at the microbiological scale, of the benthic communities (including corals) that reside in and around mid-Atlantic canyons, which are located at the edge of the continental shelf.
A pictorial overview for general audiences of key landscapes and ecosystems in South Florida; includes extensive references and links to past and current research activities relating to the South Florida ecosystem restoration effort.
Children's website on southern Florida aquatic biology with short movie clips of amphibians, games & puzzles, wildlife pictures, teacher resources, and more.
Research with a primary focus on coastal and marine environments and societal implications of natural hazards, resource sustainability, and environmental change.
Palmyra Atoll in the tropical Pacific is a "living laboratory" for multi-disciplinary research on coral reef ecosystems, insular terrestrial ecosystems, climate change, and the lingering effects of Cold War nuclear testing.
Extreme storms, sea-level rise, and the health of marine communities are some of the major societal and environmental issues studied by this part of USGS.
Explains type of information we collect and the problems we study in this area, focusing on coral reef ecosystems, ocean acidification, and sea-level change.
