SF Bay Coastal System SF Bight
SF Bight Coastal Processes Study
The USGS is conducting a study that documents and analyzes the processes that control the sand transport and sedimentation patterns of Ocean Beach, a National Park site within the Golden Gate National Recreation Area. This area encompasses a complicated coastal setting that is impacted by the tidal influence of San Francisco Bay, as well as the southwest and northwest Pacific swell. High-energy conditions at this site have restricted comprehensive field surveys in the past, but recent innovations in field techniques now make it possible to perform detailed analysis of the physical processes operating on high energy coastlines, such as Ocean Beach.
Our numerous field experiments and other data collection are ongoing at Ocean Beach. Here, we continually extend the longest coastal monitoring data set in Northern California. We've conducted monthly topographic surveys since April 2004, and close to quarterly nearshore bathymetric surveys since May 2004. Click the figure shown here, for a larger version.
