MODFLOW 6 Datasets for a Groundwater-flow Model in the Saco River Basin, New Hampshire and Maine MODFLOW 6 Datasets for a Groundwater-flow Model in the Saco River Basin, New Hampshire and Maine
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...
Seismic catalogue derived from the 2023 Kīlauea Seismic Imaging Experiment, Kīlauea, Hawai'i, USA Seismic catalogue derived from the 2023 Kīlauea Seismic Imaging Experiment, Kīlauea, Hawai'i, USA
This is a catalogue of the earthquake data recorded during the 2023 Kīlauea Seismic Imaging Experiment by a consortium of government and academic scientists under the auspices and with the coordination of the U.S. Geological Survey (USGS) and the National Park Service at Hawai'i Volcanoes National Park. Steve Roecker (Rensselaer Polytechnic Institute) produced this catalogue and then...
Radiometric analysis (cesium-137 and lead-210) at selected depth intervals from borehole core of impounded sediments in Pahranagat Wash behind Arrow Canyon Dam, northern Clark County, Nevada Radiometric analysis (cesium-137 and lead-210) at selected depth intervals from borehole core of impounded sediments in Pahranagat Wash behind Arrow Canyon Dam, northern Clark County, Nevada
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...
National assessment of shoreline change: A GIS compilation of vector shorelines (1949 to 2015) and associated shoreline change data for the west coast of Alaska, Cape Prince of Wales to Kotlik River National assessment of shoreline change: A GIS compilation of vector shorelines (1949 to 2015) and associated shoreline change data for the west coast of Alaska, Cape Prince of Wales to Kotlik River
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.
South Grand Chenier Marsh Creation (ME-20) 2024 land-water classification South Grand Chenier Marsh Creation (ME-20) 2024 land-water classification
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...
ECCOE 2025 Surface Reflectance Validation Dataset ECCOE 2025 Surface Reflectance Validation Dataset
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...
