Each one these blue dots represents a site where a storm-tide sensor bracket has been installed for the Gulf of Mexico pre-defined network. There are currently 85 brackets in Florida, 6 in Alabama, 3 in Mississippi, 18 in Louisiana and 26 in Texas, for a total of 138 bracketed sites. (Not all brackets will be used in all storms.)

The USGS creates a Flood Event Viewer for major flooding incidents, as a one-stop, interactive information source. On that website, viewers can click on each red dot (storm-tide sensor) to see details about it.

For ten years, this yellow concrete block house in Cape San Blas, Florida, dubbed Fish Inn, was the seasonal office, laboratory and living quarters for a team of USGS sea turtle researchers during their field season from November till April.
