In SF Bay, even an exceptionally wet year can't supply enough sediment to keep pace with rising seas
Study highlights a paradox for coastal managers: climate change may trigger more landslides, but most of that sediment doesn't reach coastlines

Effect of land-use change and climate on coral calcification and geochemistry: A 253-year time series from west Maui Effect of land-use change and climate on coral calcification and geochemistry: A 253-year time series from west Maui
Land-use change and climate variability both regulate land-based inputs of sediment and nutrient delivery to coral reefs, yet few records in Hawaii can identify when these land-based inputs began or how they have evolved through time. We present a 253-year (1760–2013) coral core record from Olowalu reef, Maui, spanning pre-colonial settlement through the rise and decline of sugarcane...
Dimensionality reduction techniques for analyzing tsunami simulations in hazard assessment and forecasting applications Dimensionality reduction techniques for analyzing tsunami simulations in hazard assessment and forecasting applications
A wide selection of linear and non-linear dimensionality reduction techniques is evaluated on synthetic tsunami data that is the basis for tsunami hazard assessment and computational forecasting. The data were computed from earthquake rupture forecasts (ERFs) supplying initial generation conditions and a linear long-wave Green's function approach to efficiently calculate tsunami...
A geographic dataset of rocky reefs habitat areas of particular concern for the United States West Coast A geographic dataset of rocky reefs habitat areas of particular concern for the United States West Coast
The United States National Marine Fisheries Service determines “essential fish habitat (EFH)” for federally managed species in coordination with regional fishery management councils, considers adverse effects to those habitats, and provides information to further habitat conservation and enhancement. Identifying discrete subsets of EFH as “habitat areas of particular concern (HAPC)” can...

Typhoon Merbok Disaster Recovery Project: Accomplishments
The Typhoon Merbok Disaster Emergency Recovery Efforts project addresses critical data and capacity gaps in coastal Alaska by generating high resolution environmental datasets, hazard analyses, and monitoring tools needed to quantify erosion, flooding, and permafrost-related risks at the community scale.
Geologic Mapping for Landscape Resiliency in California, Oregon, and Washington
This project uses geologic and geomorphic mapping in the context of societally relevant problems in the Earth’s critical zone. Leveraging interdisciplinary research ties and interagency collaborations, it utilizes remote sensing data, corroborated with field observations, to determine i) the spatial distribution of geomorphic processes and ages of Quaternary deposits in the context of active...

American Samoa Mapping Project
USGS scientists are leading a sampling effort to the Samoa Basin, offshore of American Samoa. This work is part of an interagency-supported three-month hydrograph survey project led by NOAA and in partnership with BOEM.
