Wave-driven water level variability (and runup at the shoreline) is a significant cause of coastal flooding induced by storms. Wave runup is challenging to predict, particularly along tropical coral reef-fringed coastlines due to the steep bathymetric profiles and large bottom roughness generated by reef organisms. The 2012 University of Western Australia Fringing Reef Experiment (UWAFRE) measured water levels and velocities for sixteen wave and offshore (still) water level conditions on a 1:36 geometric scale fringing reef profile with and without bottom roughness. Experiments were... Tags: CMGP, Coastal and Marine Geology Program, Geophysics, PCMSC, Pacific Coastal and Marine Science Center, All tags...

Elevations along channel-perpendicular transects were surveyed using a total station and prism rod. Initial geodetic control was established using static global positioning system (GPS) occupations. A total station was subsequently used to expand and maintain the survey control network at each site. All survey data were referenced to the NAD83 datum, using the UTM, zone 10, coordinate reference system. All elevations were referenced to the NAVD88 vertical datum. Based on repeat measurements of points with known positions, we estimated the horizontal and vertical accuracy of the...

As part of the USGS's California State Waters Mapping Project, a 50-m grid of sediment thickness for the seafloor within the limit of California’s State Waters between Pigeon Point and southern Monterey Bay was generated from seismic-reflection data collected in 2009 and 2010 (USGS activities (S-15-10-NC, S-N1-09-MB, and S-06-11-MB) supplemented with outcrop and geologic structure from DS 781.
