In several early studies, central California marine terraces between Santa Barbara and Point Conception were interpreted to record sea-level high stands of the last interglacial complex, ~80 ka to ~120 ka (marine isotope stage [MIS] 5). These ages and their elevations (~20 m to ~45 m) indicate modest rates of tectonic uplift, similar to those from other localities in southern and central

This model archive makes available the Soil-Water-Balance (SWB) model used to simulate potential recharge for the Saco Headwaters Watershed. This model was used to simulate potential recharge (net infiltration) for use in a groundwater model in the same region to understand the effects of water bottling. The model was used to produce a historical simulation (2000 -2021) and a series of...

A MODFLOW 6 groundwater model for the Wards Brook aquifer in New Hampshire and Maine was developed to understand the effects of groundwater withdrawals for historical and potential future conditions. The model assesses how groundwater withdrawals, including for bottled water, affect base flows from Wards Brook, groundwater levels, and pond levels under different scenarios. Model runs...

This data release from the U.S. Geological Survey (USGS) presents the results of radiometric analyses conducted on sediment samples collected in 2016 and 2019 from Pahranagat Wash, behind Arrow Canyon Dam in northern Clark County, Nevada. In 2016, core samples were collected from two well sites: USGS 364453114483401 (ACWEST) and USGS 364448114481001 (ACEAST). Additionally, a shallow...

This data release comprises geospatial data of historical shoreline positions and long-term (greater than 60 years) and short-term (less than 40 years) rate of change statistics from the west coast of Alaska from Cape Prince of Wales to Kotlik River for the years 1949 to 2015.

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

Scientists and engineers from the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS) Cal/Val Center of Excellence (ECCOE) collected in situ measurements using field spectrometers to support the validation of surface reflectance products derived from Earth observing remote sensing imagery. Data provided in this data release were collected during select...

This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2021. Wetlands were classified using the Cowardin, et al., (1979) wetlands classification scheme to the level of freshwater and tidal salinity modifiers. For this dataset, upland...

The US Geological Survey has collected daily streamflow data at more than 20,000 locations within the conterminous United States (CONUS). Although these data are publicly available, there is little to no information about the environmental setting under which the data were collected. Specifically, users of the data have no readily available means to determine whether the observed...

This data release provides vector flight-line (point) and raster data for a high-resolution airborne magnetic and radiometric survey over a part of the eastern Great Basin, Nevada. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating...

This data release presents portable X-ray fluorescence (pXRF) data and physical properties (grain density, saturated bulk density, dry bulk density, and magnetic susceptibility) of 30 rock samples collected from an Earth MRI survey area in northeastern Washington, USA. Rock type information (age and lithology) are also included. The rock samples were initially collected for low...
