Topobathymetric data for Tampa Bay, Florida Topobathymetric data for Tampa Bay, Florida
Topobathymetric data (“topobathy”) are a merged rendering of both topography (land elevation) and bathymetry (water depth) to provide a single product useful for inundation mapping and a variety of other applications. These data were developed using one topographic and two bathymetric datasets collected at different dates. Topography was obtained from the U.S. Geological Survey's (USGS)...

Changes in the fluorescence of the Caribbean coral Montastraea faveolata during heat-induced bleaching Changes in the fluorescence of the Caribbean coral Montastraea faveolata during heat-induced bleaching
In order to evaluate the response of commonly occurring green and orange fluorescent host-based pigments, a thermal stress experiment was performed on specimens of the Caribbean coral Montastraea faveolata. Seven paired samples were collected from a small oceanic reef near Lee Stocking Island in the Bahamas. Seven of the fourteen corals were subjected to elevated temperatures for 28 d...
