Climate impacts on Monterey Bay area beaches
For beach towns around Monterey Bay, preserving the beaches by mitigating coastal erosion is vital. Surveys conducted now and regularly in the future will help scientists understand the short- and long-term impacts of climate change, El Niño years, and sea-level rise on a populated and vulnerable coastline.
PS-CoSMoS: Puget Sound Coastal Storm Modeling System
The CoSMoS model is currently available for most of the California coast and is now being expanded to support the 4.5 million coastal residents of the Puget Sound region, with emphasis on the communities bordering the sound.
Coastal Storm Modeling System (CoSMoS)
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales. CoSMoS was developed for hindcast studies, operational applications and future climate scenarios to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety...
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.
Estuaries and large river deltas in the Pacific Northwest
Essential habitat for wild salmon and other wildlife borders river deltas and estuaries in the Pacific Northwest. These estuaries also support industry, agriculture, and a large human population that’s expected to double by the year 2060, but each could suffer from more severe river floods, higher sea level, and storm surges caused by climate change.
CoSMoS-Groundwater
The USGS Coastal Storm Modeling System (CoSMoS) team has extensively studied overland flooding and coastal change due to rising seas and storms. Interactions with coastal stakeholders have elucidated another important question; will rising seas also intrude into coastal aquifers and raise groundwater tables? The CoSMoS-Groundwater (CoSMoS-GW) modeling effort seeks to provide initial insight into...
Using Video Imagery to Study Coastal Change: Whidbey Island
From May of 2018 through November of 2019, USGS scientists collected imagery from video cameras overlooking the coast along a beach on Whidbey Island, Island County at the northern boundary of Puget Sound in western Washington.
CoSMoS 3.1: Central California
CoSMoS v3.1 for central California shows projections for future climate scenarios (sea-level rise and storms)
Using Video Imagery to Study Wave Dynamics: Isla Verde
USGS scientists installed video cameras atop a building and oceanographic instruments off San Juan, Puerto Rico, to better understand how waves move across coral reefs and cause flooding on tropical shorelines.
Climate Change on U.S. Arctic Ocean Margins
Arctic Alaska is warming faster than the rest of the United States. A major consequence of this warming is permafrost thaw, which threatens infrastructure, alters habitat, increases fire risk, changes nutrient and sediment delivery to the coastal ocean, and enhances greenhouse gas release. The warming climate has already dramatically reduced the thickness and annual duration of sea ice, rendering...
