Lifespan of marsh units in Eastern Shore of Virginia salt marshes Lifespan of marsh units in Eastern Shore of Virginia salt marshes
The lifespans of salt marshes in Atlantic-facing Eastern Shore of Virginia are calculated based on estimated sediment supply and sea-level rise (SLR) predictions, following the methodology of Ganju and others (2020). The salt marsh delineations are from Ackerman and others (2023). The SLR predictions are local estimates corresponding to increases of 0.3, 0.5 and 1.0 meter in global mean...
Lifespan of marsh units in Connecticut salt marshes Lifespan of marsh units in Connecticut salt marshes
The lifespans of salt marshes in Connecticut are calculated based on estimated sediment supply and sea-level rise (SLR) predictions, following the methodology of Ganju and others (2020). The salt marsh delineations are from Ackerman and others (2023). The SLR predictions are local estimates corresponding to increases of 0.3, 0.5 and 1.0 meter in global mean sea level (GMSL) by 2100, as...
Beach foreshore slope for the East Coast of the United States Beach foreshore slope for the East Coast of the United States
This data release contains foreshore slopes for primarily open-ocean sandy beaches along the East Coast of the United States (Maine through Florida). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 1997 and 2018. The shoreline positions have been previously published, but the slopes have not. A reference baseline was defined...
Deep SEARCH eDNA metabarcoding data Deep SEARCH eDNA metabarcoding data
The Deep SEARCH Project (Deep sea exploration to advance research on cold corals/canyon/cold seep habitats) included a cruise in April 2019 aboard the NOAA ship Ron Brown to various sites along the Mid-Atlantic North American coast. An ROV was used to collect samples of bottom water at these sites, which were then subjected to eDNA extraction and analyses. This data release describes...
USGS National and Global Oil and Gas Assessment Project—Black Sea Area: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—Black Sea Area: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the Black Sea area. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is...
Update of the Database for Volcanic Processes and Geology of Augustine Volcano, Alaska to National Geologic Map Schema Update of the Database for Volcanic Processes and Geology of Augustine Volcano, Alaska to National Geologic Map Schema
The geologic map database in this data release is a reproduction of the U.S. Geological Survey Professional Paper 1762: Volcanic Processes and Geology of Augustine Volcano, Alaska, Waitt and Begét (2009). The database consists of a geologic map and one structural cross section that conform to the National Geologic Map Schema (GeMS). These data supersede USGS Data Series 677: Database for...
Ground-surface elevation, vegetation, and land type within approximately 10 and 400 meters of 176 water-level gaging stations in the Greater Everglades, Florida 2005-10 Ground-surface elevation, vegetation, and land type within approximately 10 and 400 meters of 176 water-level gaging stations in the Greater Everglades, Florida 2005-10
The Everglades Depth Estimation Network (EDEN) is an integrated network of water-level gages, interpolation models, web applications, and decision support tools that generates daily water-level data and derived hydrologic data across the freshwater part of south Florida's Greater Everglades. EDEN provides continuous daily water-level and depth surfaces on a 400-meter grid using an...
Clothianidin concentrations in milkweed leaves that leads to prepupal mortality in monarch butterflies Clothianidin concentrations in milkweed leaves that leads to prepupal mortality in monarch butterflies
A set of experiments was conducted to determine the dietary clothianidin exposures that cause prepupal mortality in the absence of other adverse effects. Monarch larvae were raised from hatch to pupae on clothianidin contaminated swamp milkweed plants. Larval growth, larval survival, and prepupal survival were monitored throughout the experiments in which the exposures ranged from 1.4 –...
Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis
This study generated genetic 'barcode' data using high-throughput sequencing to characterize pollen collected by the endangered rusty-patched bumblebee, Bombus affinis. Pollen samples were associated with a single Bombus affinis colony within a structure in Red Wing, Minnesota, USA, as previously described by Boone et al. (2022). This data release consists of two tab-delimited files: 1)...
Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon
Scoggins Dam in northwest Oregon lies within the Gales Creek fault zone (GCF), a northwest-striking system of active faults forming the boundary between the Coast Range and the Tualatin Valley about 25 km east of Portland, Oregon. Geologic mapping published in 2020 shows the dam to lie within a block-faulted releasing stepover between the right-lateral, NW-striking Scoggins Creek and...
Mercury concentrations in dragonfly larvae from the Willamette River Basin, 2023 Mercury concentrations in dragonfly larvae from the Willamette River Basin, 2023
Comma-separated values (.csv) file containing data related to mercury concentrations in dragonfly samples from the Willamette River Basin collected in 2023.
Conservation Efforts Database Spatial Reporting Units (SRUs) Conservation Efforts Database Spatial Reporting Units (SRUs)
This geospatial layer is a spatial index for the Conservation Efforts Database (CED, https://conservationefforts.org/), serving as a spatial framework for summary reports by area (a.k.a. polygon). In addition, this SRU (Sagebrush Reporting Unit) data is an option for data providers to provide spatial ambiguity to alleviate concerns of too much spatial detail representing private...
