Post-Fire Sediment Research at the Pacific Coastal and Marine Science Center
The USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California, has been growing our post-fire research contributions since 2017, through studies of post-fire sediment movement that address the Natural Hazards Mission Area objectives for understanding wildfire hazards.
USGS CoastCams
The U.S. Geological Survey (USGS) uses a nationwide network of coastal observing cameras, or CoastCams, to monitor coastal conditions in near real-time and support research by the USGS and its partners into a variety of coastal processes and hazards. The most recent CoastCam images are made publicly available within minutes of data collection and can be accessed using the links below or by...
Remote Sensing Coastal Change
We use remote-sensing technologies—such as aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.
Sediment Transport in Coastal Environments
Our research goals are to provide the scientific information, knowledge, and tools required to ensure that decisions about land and resource use, management practices, and future development in the coastal zone and adjacent watersheds can be evaluated with a complete understanding of the probable effects on coastal ecosystems and communities, and a full assessment of their vulnerability to natural...
Using Video Imagery to Study Coastal Change: Santa Cruz Beaches
Two video cameras atop the Dream Inn hotel in Santa Cruz, California, overlook the coast in northern Monterey Bay. One camera looks eastward over Santa Cruz Main Beach and boardwalk, while the other looks southward over Cowells Beach.
Transport of invasive microorganisms
The objectives of his project are to investigate the vectors and timing of microbiological invasions and the subsequent dispersal of these non-native organisms due to sediment transport. We will attempt to confirm the identification of specific invasives encountered with molecular sequencing, monitor the spread of the invading populations through their recent distribution and the historic...
Sediment transport in submarine canyons
Objectives: Produce a step-change in understanding of submarine turbidity currents by measuring their two key features (synchronous velocity and concentration profiles) in detail (every 2-to-30 seconds) for the first time, and documenting spatial changes in their flow velocity from source-to-sink for the first time.
Sediment transport between estuarine habitats in San Francisco Bay
We investigate mechanisms of sediment transport, resuspension dynamics in shoals, wave evolution in the shallows, wave attenuation in marshes, and transport of sediment between mudflats and marshes. We produce data sets for calibration of and comparison with sediment transport models, including wave parameters, suspended sediment concentration, and sediment flux.
Drag and sediment transport: conditions at the bottom boundary
Research on bed sediment grain size, bedform morphology, vegetation characteristics, and sediment resuspension and transport.
Using Video Imagery to Study Wave Dynamics: Unalakleet
USGS scientists installed two video cameras atop a windmill tower in Unalakleet, Alaska, pointing westward over Norton Sound, to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.
Using Video Imagery to Study Sediment Transport and Wave Dynamics: Nuvuk (Point Barrow)
Two coastal observing video cameras are installed atop a utility pole near the northernmost point of land in the United States, at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas, and will be used to observe and quantify coastal processes such as wave run-up, bluff erosion, movement of sandbars and ice floes...
Using Video Imagery to Study Coastal Change: Sunset State Beach
Two video cameras overlook the coast at Sunset State Beach in Watsonville, California. Camera 1 looks northwest while Camera 2 looks north. The cameras are part of the Remote Sensing Coastal Change project.
