Post-fire sediment yield from a western Sierra Nevada watershed burned by the 2021 Caldor Fire
Watershed sediment yield commonly increases after wildfire, often causing negative impacts to downstream infrastructure and water resources. Post-fire erosion is important to understand and quantify because it is increasingly placing water supplies, habitat, communities, and infrastructure at risk as fire regimes intensify in a warming climate. However, measurements of post-fire sediment...
Shoreline change of western Long Island, New York, from satellite-derived shorelines
Shoreline measurement techniques using satellite-derived imagery can provide decades of observations of shoreline change. Here we apply these techniques to the western south shore of Long Island, New York, which has three distinct beaches, Rockaway Peninsula, Long Beach, and Jones Beach Island, which are 18, 15, and 24 km in length, respectively. These beaches are recreation areas for...
Predicted exposure of communities in southeastern United States to climate-related coastal hazards
A rigorous analysis of 21st Century multi-hazard exposure for U.S. Southeast Atlantic coastal communities indicates that up to 70% of residents will be exposed daily to shallow and emerging groundwater by ~2100, 15 times higher than from surficial flooding alone. This threat further exacerbates other coastal stressors, such as flooding, subsidence, and beach erosion, that impact these...

Coastal Wetland Vulnerability to Climate Change and Sea-Level Rise: Understanding Ecological Thresholds and Ecosystem Transformations
Eighteen USGS coastal scientists from all four coasts of the conterminous United States are working together to advance the understanding of climate change and sea-level rise impacts to coastal wetlands.

Habitat Vulnerability to Climate Change: Identifying Climate Change Induced Mass Mortality Events Across Large Landscapes of the United States
USGS researchers will characterize extreme climatic events across U.S. following a review of case studies of mass mortality events associated with climate extremes including drought, precipitation, freeze, heat waves, and storm events.
Eyes on Earth Episode 120 – Mapping the California Coastline
Coastline erosion can change your favorite beach. But it can also affect highways and buildings. Landsat, along with high-resolution data, can be used to model the past and predict the future of changes caused by sea level rise and coastal erosion.
