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.
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.
Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for water chemistry and mercury in fish tissue to establish unbiased baseline data.
Constructed farm ponds represent significant breeding, rearing, and overwintering habitat for amphibians in the Driftless Area Ecoregion of Minnesota, Wisconsin, and Iowa. Links to fact sheet, brochure, annual reports, field manual, and final report.
Field methods, topics of investigation, shoreline changes, publications, and satellite imagery related to geologic and hydrologic processes affecting Lake Pontchartrain and adjacent lakes which form a large estuary in the Gulf Coast region.
