Complete Bouguer gravity data of Kīlauea, Island of Hawaiʻi, 2023. Complete Bouguer gravity data of Kīlauea, Island of Hawaiʻi, 2023.
The attached file contains complete Bouguer gravity data collected at Kīlauea volcano from 1/5/2023 - 1/26/2023 using a Scintrex CG-6 gravimeter. Overview A Bouguer gravity survey of Kīlauea’s summit was carried out in January 2023 across a grid extending 3 km north, east, and west of the caldera and 6 km to the south (Ruggles and Flinders, 2026). The survey focused on areas with...

Numerical Simulations of Hurricane Sally at Panama City, Florida: Model Inputs and Outputs Numerical Simulations of Hurricane Sally at Panama City, Florida: Model Inputs and Outputs
This data release contains model inputs and outputs for simulations of hydrodynamic conditions at Panama City, Florida (FL), for Hurricane Sally in September 2020 with the Deltares® XBeach numerical model using methods described in Roelvink and others (2009). The simulations were performed in collaboration with investigators at the U.S. Naval Research Laboratory (NRL) who deployed...
Modeling of nutrient and sediment concentrations and loads for Clear Lake California, using RLOADEST Modeling of nutrient and sediment concentrations and loads for Clear Lake California, using RLOADEST
Models of daily mass loads of nutrient species constituents and suspended sediment at tributary locations using water quality measurements and stream discharge from river gauging stations were developed to estimate nutrient and suspended sediment mass loads flowing into the Clear Lake watershed. Mass loads are calculated by multiplying stream discharge, measured as volume per time, by...
SPARROW model inputs and simulated Total Nitrogen and Total Phosphorus loads in the Clear Lake watershed, California SPARROW model inputs and simulated Total Nitrogen and Total Phosphorus loads in the Clear Lake watershed, California
The existing long-term Total Nitrogen (TN) and Total Phosphorus (TP) steady-state models, originally developed on a regional scale for the Pacific Region of the United States (Wise, 2019), were utilized to estimate TN and TP loads for the Clear Lake watershed. To support this analysis, input data for the Pacific Region model were updated to reflect climate, land use, and agricultural...
Stream Temperature and Thermal Sensitivity in Pacific Northwest Forest Plan Aquatic Monitoring Sites (2010 - 2019) Stream Temperature and Thermal Sensitivity in Pacific Northwest Forest Plan Aquatic Monitoring Sites (2010 - 2019)
Stream temperatures were monitored year-round in select sub-watersheds across the Aquatic and Riparian Effectiveness Monitoring Program (AREMP) area from 2010 to 2019. Data from these surveys were compiled to (1) statistically analyze paired water-air temperature data, (2) quantify the sensitivity of their thermal regime, and (3) determine the relative importance of management actions...
Experimental data for Bloater (Coregonus hoyi) embryo hatch survival, development, and growth in four different substrate types Experimental data for Bloater (Coregonus hoyi) embryo hatch survival, development, and growth in four different substrate types
Bloater (Coregonus hoyi) are an extirpated deepwater fish species in Lake America (Lake Ontario). A Bloater reintroduction initiative began in 2012; however annual stocking efforts were unable to yield a self-sustaining population in Lake America. Unsuitable spawning habitat was hypothesized as a potential impediment to natural reproduction, due to observations of Dreissenid mussel...
Fire Invasive Response Metric (FIRM) and Habitat Invasive Risk (HIR) for Western U.S. Rangelands Fire Invasive Response Metric (FIRM) and Habitat Invasive Risk (HIR) for Western U.S. Rangelands
Short-term Fire Invasive Response Metric (FIRM) (2016-2024), Long-term FIRM (1985-2024), and Habitat Invasive Risk (HIR) quantify wildfire-driven invasive annual grass responses across western U.S. rangelands. Context - Understanding the relationship between Exotic Annual Grass (EAG) expansion, drought, and fire frequency across western US rangelands is complex, but critical for...
Central Everglades Planning Project Operational Plan 1.0 (CEPP Ops 1.0) Ecological Model Support, Round 3 Central Everglades Planning Project Operational Plan 1.0 (CEPP Ops 1.0) Ecological Model Support, Round 3
Ecological models facilitate evaluation of alternative approaches to restore the Greater Everglades ecosystem. However, the provision of useful and accessible models is a challenge because there is often a disconnect between model output and its use by decision makers. Joint Ecosystem Modeling (JEM) meets this challenge by providing ecological model output tailored to management...
Geologic Map Schema (GeMS) Engineering data for the 1953 USGS publication of the Hollidaysburg quadrangle, Pennsylvania Geologic Map Schema (GeMS) Engineering data for the 1953 USGS publication of the Hollidaysburg quadrangle, Pennsylvania
This GeMS dataset depicts the age and type of geologic materials (rock or sediment) at or near the surface of Hollidaysburg, Pennsylvania and includes additional interpretive data pertaining to geological engineering properties in GeMS format.
Louisiana Barrier Island Comprehensive Monitoring Program – 2016–2021 habitat change, Late Lafourche Delta Region Louisiana Barrier Island Comprehensive Monitoring Program – 2016–2021 habitat change, Late Lafourche Delta Region
The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...
