Characterizing sedimentary organic carbon in a hydrothermal spreading center, the Escanaba Trough
Sediments in critical marine mineral environments are of wide importance due to their preservation of both marine minerals and organic carbon (OC) stocks. However, OC storage and cycling is often overlooked in mineral system studies. This work characterizes sedimentary OC within the Escanaba Trough, a hydrothermal sulfide system off the coast of northern California. By utilizing ROV...
Shoreline seasonality of California’s beaches
We report on remote sensing techniques developed to characterize seasonal shoreline cycles from satellite-derived shoreline measurements. These techniques are applied to 22-yr of shoreline measurements for over 777 km of beach along California's 1,700-km coast, for which the general understanding is that shorelines exhibit winter-narrow and summer-recovery seasonality. We find that...
Coral reef restoration can reduce coastal contamination and pollution hazards
Coral reef restoration can reduce the wave-driven flooding for coastal communities. However, this protection has yet to be assessed in terms of the reduced risk of flood-driven environmental contamination. Here we provide the first high-resolution valuation of the reduction of flood-related land-based environmental pollution provided by potential coral reef restoration. Along Florida’s...

Information Sheet: Marine Mineral Resources and USGS Studies
The U.S. Geological Survey (USGS) provides science and data on offshore mineral resources and ecosystems, as well as any potential hazards associated with extraction. Society relies on minerals for infrastructure, technology, manufacturing, and energy production; critical minerals are essential to the economic or national security of the United States and have a supply chain vulnerable to...
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.
