Bathymetric change analysis in San Francisco Bay, California, from 1971 to 2020

This data release supersedes version 1.0, published in April 2023 at https://doi.org/10.5066/P9Y5PEV0. Versioning details are documented in the accompanying SFBay_BathyChange_VersionHistory.txt file.  This data release provides bathymetric change grids of four geographic areas of San Francisco Bay, California, comparing digital elevation models (DEMs) created from bathymetric data collected in the

Height, live canopy volume and annual ring widths of cottonwood trees along the Yampa and Green rivers in Dinosaur National Monument and Canyonlands National Park, Colorado and Utah

We measured the percent live canopy and height of randomly-selected cottonwood trees at three sites: Deerlodge Park on the Yampa River (DLP), Island Park on the upper Green (ILP), and Canyonlands National Park on the lower Green (CAN). From these same trees we took increment cores to understand differences in tree growth in each forest over time. This dataset includes four tabular digital files. T

Annotated bibliography of 64 papers reviewed and summarized in a conceptual framework to assess post-wildfire water quality

We conducted a scoping review to assess the current state of the science and knowledge gaps of post-wildfire water quality. A scoping review is a rapid, systematic approach that is more superficial compared to traditional reviews, and can be considered a preliminary study that informs future in-depth reviews, meta-analyses, or modelling efforts (Robinne et al., 2020). We developed a driver, factor

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 sea level

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 projected b

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, and then 20

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 what samples

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 defined w

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 Volcanic

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 interpolation al

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 – 2,793.1 ng

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).
