Seafloor Elevation Change From 2017 to 2018 at a Subsection of Crocker Reef, Florida Keys-Impacts from Hurricane Irma

Online link
Description The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes at a subsection of Crocker Reef near Islamorada, Florida (FL), within a 6.1 square-kilometer area following the landfall of Hurricane Irma in September 2017. USGS staff used USGS multibeam data collected between October 10 and December 8, 2017 (Fredericks and others, 2019) and March 8-15, 2018 (Fredericks and others, 2019) to assess changes in seafloor elevation and structure in the months following the passage of Hurricane Irma. An elevation change analysis between the 2017 and 2018 USGS multibeam data was performed to quantify and map impacts to seafloor elevations and to determine elevation and volume change statistics for seven habitat types found within a subsection of Crocker Reef, FL.
