Physics-based numerical circulation model outputs of ocean surface circulation during the 2010-2013 summer coral-spawning seasons in Maui Nui, Hawaii, USA Physics-based numerical circulation model outputs of ocean surface circulation during the 2010-2013 summer coral-spawning seasons in Maui Nui, Hawaii, USA
Here we present surface current results from a physics-based, 3-dimensional coupled ocean-atmosphere numerical model that was generated to understand coral larval dispersal patterns in Maui Nui, Hawaii, USA. The model was used to simulate coral larval dispersal patterns from a number of existing State-managed reefs and large tracks of reefs with high coral coverage that might be good...
Marine geophysical data - Point Sal to Refugio State Beach, southern California Marine geophysical data - Point Sal to Refugio State Beach, southern California
This data release includes approximately 1,032 km of marine single-channel seismic-reflection data collected by the U.S. Geological Survey on a research cruise (USGS survey 2014-632-FA) in July and August, 2014, between Point Sal and Refugio State Beach. The dataset includes 168 profiles, most of which were collected on tracklines roughly perpendicular to the coast at 1 km line spacing...
Digital image mosaics of the nearshore coastal waters of selected areas on the Hawaiian Islands of Hawai'i, Maui, Moloka'i, and O'ahu using aerial photographs and SHOALS airborne lidar bathymetry data Digital image mosaics of the nearshore coastal waters of selected areas on the Hawaiian Islands of Hawai'i, Maui, Moloka'i, and O'ahu using aerial photographs and SHOALS airborne lidar bathymetry data
The lack of geographic and thematic maps of coral reefs limits our understanding of reefs and our ability to assess change. The U.S. Geological Survey (USGS) has the capability to compile digital image mosaics that are useful for creating detailed map products. Image maps covering the shallow near-shore coastal waters have been produced for several of the main Hawaiian Islands, including...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, September 2014 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, September 2014
Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a...

Nearshore waves in southern California: hindcast, and modeled historical and 21st-century projected time series Nearshore waves in southern California: hindcast, and modeled historical and 21st-century projected time series
As part of the Coastal Storm Modeling System (CoSMoS), time series of hindcast, historical, and 21st-century nearshore wave parameters (wave height, period, and direction) were simulated for the southern California coast from Point Conception to the Mexican border. The hindcast (1980-2010) time series represents reanalysis-forced offshore waves propagated to the nearshore, whereas the...
Sediment core data from the northern flank of Monterey Canyon, offshore California Sediment core data from the northern flank of Monterey Canyon, offshore California
The five files included in this U.S. Geological Survey data release are data from a set of sediment cores acquired from the continental slope, north of Monterey Canyon, offshore central California. Vibracores and push cores were collected with the Monterey Bay Aquarium Research Institutes remotely operated vehicle (ROV) Doc Ricketts in 2014 (cruise ID 2014-615-FA). One spreadsheet
Alaska Digitize Project Alaska Digitize Project
Processing methodology for the seafloor substrate data required multiple steps to georegister, digitize, clean, and validate the datasets. Sediments such as gravel, sand, and mud were available as verbal notations on the smooth sheets and the data on any one smooth sheet were digitized by one person and then proofed by another. Once the locations of the sediment point data were collected...
High-resolution multibeam bathymetry and backscatter data collected in 2004 for the northern Channel Islands region, southern California High-resolution multibeam bathymetry and backscatter data collected in 2004 for the northern Channel Islands region, southern California
This data release presents data for 5-m resolution multibeam-bathymetry and acoustic-backsccatter data of the northern Channel Islands region, southern California. In 2004 the U.S. Geological Survey, Pacific Coastal and Marine Science Center collected multibeam-bathymetry and acoustic-backscatter data in the northern Channel Islands region, southern California. The region was mapped...
