Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
Coastal/Marine Hazards and Resources
USGS Coastal/Marine Hazards and Resources Program scientists and staff study coastal and ocean resources and processes from shorelines and estuaries to the continental shelf and deep sea.
Research Marine Biologist Ilsa Kuffner, Research Oceanographer Lauren Toth, and Oceanographer Anastasios Stathakopoulos will travel to Key Largo, FL, December 10 to 14 to attend "Reef Futures 2018: A Coral Restoration and Intervention-Science Symposium."
The Anchialine Biogeochemistry Research Team has returned to the Yucatan Peninsula Mexico to continue investigating how life persists within underwater coastal caves beneath the tropical forest.
USGS scientist selected as next editor-in-chief of AGU’s Journal of Geophysical Research: Earth Surface
USGS research geologist Amy East, of the Pacific Coastal and Marine Science Center, will be the next editor-in-chief of the American Geophysical Union’s Journal of Geophysical Research: Earth Surface, beginning January 1, 2019.
Geochemical sourcing of runoff from a young volcanic watershed to an impacted coral reef in Pelekane Bay, Hawaii
Runoff of sediment and other contaminants from developed watersheds threatens coastal ecosystems and services. A sediment geochemical sourcing study was undertaken on a sediment-impacted coral reef flat to identify terrestrial sediment sources and how these changed over time. Geochemical signatures were identified for watershed...Takesue, Renee K.; Storlazzi, Curt D.
Controls on submarine canyon head evolution: Monterey Canyon, offshore central California
The Monterey submarine canyon, incised across the continental shelf in Monterey Bay, California, provides a record of the link between onshore tectonism, fluvial transport, and deep-marine deposition. High-resolution seismic-reflection imaging in Monterey Bay reveals an extensive paleocanyon unit buried below the seafloor of the continental shelf...Maier, Katherine L.; Johnson, Samuel Y.; Hart, Patrick E.
Statistical approach to neural network imaging of karst systems in 3D seismic reflection data
The current lack of a robust, standardized technique for geophysical mapping of karst systems can be attributed to both the complexity of the environment and prior technological limitations. Abrupt lateral variations in physical properties that are inherent to karst systems generate significant geophysical noise, challenging conventional seismic...Ebuna, Daniel; Kluesner, Jared W.; Cunningham, Kevin J.; Edwards, Joel H.
