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.)
Describes research to assess the effectiveness of the current system and distribution of marine reserves and protected areas in the Virgin Islands and Puerto Rico for conserving reef ecosystems and resources.
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.
Fact sheet on hazards from earthquakes and tsunamis in Puerto Rico and the U.S. Virgin Islands to be downloaded as a PDF file or viewed as an Adobe Acrobat Reader file.
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.
