This report documents the findings of Year Five of the cooperative agreement between the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) of the United States Department of the Interior (previously the Minerals Management Service of the U.S. Department of Interior (MMS)) and the Florida Geological Survey (FGS) to investigate the available restoration-quality sand resources offshore of the northeastern coast of Florida. Its purpose is to locate and characterize both the areal extent and volume of restoration quality sand resources lying in federal waters offshore northeastern Florida which are available for beach renourishment. This goal is being accomplished through the use of seismic reflection profiling, seabed sampling and beach sediment sampling, as well as the analysis of offshore vibracore data.

The area of the agreement includes Nassau, Duval, St. Johns, Flagler, Volusia and Northern Brevard Counties and their beaches as well as adjacent federal water from three (3) nautical miles (5.6 kilometers) to sixteen (16) nautical miles (29.6 kilometers) offshore. The specific study are of this report is that portion of the State of Florida consisting of Volusia and Northern Brevard Counties and their beaches as well as adjacent federal water from three (3) nautical miles (5.6 kilometers) to thirteen (13) nautical miles (24.1 kilometers) offshore. Analysis of sediment samples collected in Nassau, Duval, St. Johns, and Flagler counties, which was reported in the previous reports of Years One through Four, has not been duplicated in this report.
