Description

Abstract: These records contain seafloor bathymetry data (depth), backscatter data (reflectivity of the seafloor), and data visualizations (shaded and color-coded seafloor maps) for a multibeam bathymetry survey of the Rogue River Reef complex and adjacent areas. The high-resolution multibeam bathymetry survey was conducted by ODFW and Oregon State University staff in 2024-2025. The survey, off Gold Beach Oregon, covered the Rogue River Reef rocky seafloor complex and the nearby Breakers Reef just to the north. The survey was funded by a grant to ODFW from the Oregon Ocean Science Trust. Seafloor data have not yet been classified according to substrate type, but rocky seafloor structure are visualized in hillshaded maps. Contour maps are also provided.

Purpose: Seafloor bathymetry data form the foundation for studies of nearshore rocky reef ecology. These data will enable researchers to plan and implement efficient and safe field ecological sampling plans. Studying this reef system is important because it supports a long-productive sea urchin fishery and is one of the last substantial strongholds of bull kelp in Oregon. The data support safer navigation for the boating community, while recognizing that mariners must rely on official navigation charts published by NOAA. The data will be submitted to NOAA through their External Source Data Program and will be subjected to NOAA’s quality review standards for incorporation into future production of regional high-resolution charts. The maps provided here are not intended for navigation.
