Data

Classified map of crop types in California's Central Valley generated using artificial neural network multilayer perceptron models and Harmonized Landsat-8 Sentinel-2 Landsat 30m (HLSL30) data. The model was trained on data from the year 2021 and validated on the independent year 2022.

This dataset consists of annual raster maps of ecosystem carbon stocks, land use and land cover classes, and transition probabilities for the State of California during historical (1985-2020) and projected future (2021-2100) time periods. Data are simulation model output from the The Land Use and Carbon Simulator (LUCAS; Sleeter et al. 2022) run under different future climate and land...

Increasing soil carbon sequestration is part of a suite of approaches to reducing atmospheric carbon and addressing climate change. The soil carbon sequestration capability of a landscape is a function of ecological, edaphic, climatic, and anthropogenic factors. Landscape degradation is associated with a loss of soil carbon, but ecological restoration, alternative agricultural techniques...

These datasets support the conclusions in the journal article entitled "National population exposure and evacuation potential in the United States to earthquake-generated tsunami threats " as described in the abstract below: Previous efforts to characterize tsunami threats to people have focused primarily on individual scenarios in specific areas but have not recognized multiple...

The communities of the Commonwealth of the Northern Mariana Islands are threatened by tsunamis. Experts conducted earthquake and tsunami modeling to estimate the extent of tsunami inundation resulting from a Mariana Subduction Zone (MSZ) earthquake. The USGS Pedestrian Evacuation Analyst Tool (PEAT) was run to estimate pedestrian evacuation travel times out of the MSZ tsunami-hazard zone...

Many coastal communities in Alaska are threatened by tsunamis that could be generated by earthquakes associated with the Aleutian-Alaskan subduction zone (AASZ). Potential tsunami inundation from various AASZ earthquake scenarios has been modeled by others and related tsunami-hazard zones have been published (see supplemental information). We used the USGS Pedestrian Evacuation Analyst...

The communities of Puerto Rico are threatened by tsunamis from many earthquake sources (scenarios). Earthquake and tsunami modeling was conducted by experts to recognize as many earthquake sources as possible. Of the 34 tsunami scenarios developed, experts found that 16 could inundate some areas of Puerto Rico where people live and work with significant distance to safety. Pedestrian...

Intertidal microbial biofilms, or microphytobenthos, support estuarine biogeochemical cycling, the physical stability of mudflats, and food webs, particularly those of migratory shorebirds. Photosynthetic biofilms dominated by diatoms, cyanobacteria and chlorophytes represent a significant fraction of biofilm biomass and contain pigments that can be detected with remote sensing. These...

This is a 4cm resolution Digital Terrain Model (DTM) raster derived from an Unoccupied Aerial System (UAS; a DJI M600 equipped with a YellowScan Mapper+), lidar collected on March 26, 2024 by the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO). It covers a southern portion of Palo Alto Battlefield National Historic Park in the Lower Rio Grande Valley of South Texas.

These datasets support the conclusions in the journal article entitled "Population vulnerability of residents, employees, and cruise-ship passengers to tsunami hazards in complex seismic regions: a case study of the U.S. Virgin Islands" as described in the abstract below: Reducing the potential for loss of life from tsunamis is challenging on islands located in complex seismic regions...

These data support the following publication: "Assessing causes and consequences of winter surface water dynamics in California’s Central Valley using satellite remote sensing". The file contains information associated with surface water inundation, antecedent soil moisture, and atmospheric river storm characteristics for 2003-2023 in the three HUC-4 hydrologic sub-basins that make up...

This dataset includes high-resolution topography data and orthomosaics used to monitor surface change in two stream sites in Red Clover Valley, Plumas County, California. The first site is a segment of lower Dixie Creek (LDC), which accumulates flows from Dixie Mountain and drains into Red Clover Creek. The second site is an intermittent stream referred to as Subchannel B (SCB), which...
