Sea-Floor Sediment Samples, Seabed Imagery, and CTD Instrument Data Collected on Stellwagen Bank in November, 2014, U.S. Geological Survey Field Activity 2014-066-FA Sea-Floor Sediment Samples, Seabed Imagery, and CTD Instrument Data Collected on Stellwagen Bank in November, 2014, U.S. Geological Survey Field Activity 2014-066-FA
This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the...

St. Louis River estuary (Minnesota-Wisconsin) EFDC hydrodynamic model for discharge and temperature simulations: 2016-17 St. Louis River estuary (Minnesota-Wisconsin) EFDC hydrodynamic model for discharge and temperature simulations: 2016-17
The U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers Engineer Research and Development Center and the U.S. Environmental Protection Agency, developed a predictive, mechanistic, three-dimensional hydrodynamic model for the St. Louis River Estuary (SLRE), Minnesota. This model was developed with Environmental Fluid Dynamics Code (EFDC), a grid-based...
LCMAP CONUS Reference Data Product 1984-2018 land cover, land use and change process attributes LCMAP CONUS Reference Data Product 1984-2018 land cover, land use and change process attributes
The LCMAP Reference Data Product was utilized for evaluation and validation of the Land Change Monitoring, Assessment, and Projection (LCMAP) land cover and land cover change products. The LCMAP Reference Data Product includes the collection of an independent dataset of 25,000 randomly-distributed 30-meter by 30-meter plots across the conterminous United States (CONUS). This dataset was...
Inundation observations and inundation model predictions for vernal pools of the northeastern United States Inundation observations and inundation model predictions for vernal pools of the northeastern United States
This data release includes data-processing scripts, data products, and associated metadata for a study to model the hydrology of several hundred vernal pools (i.e., seasonal pools or ephemeral wetlands) across the northeastern United States. More information on this study is available from the project website. This data release consists of several components: (1) an input dataset and...
SQUID-5 structure-from-motion point clouds, bathymetric maps, orthomosaics, and underwater photos of coral reefs in Florida, 2019 SQUID-5 structure-from-motion point clouds, bathymetric maps, orthomosaics, and underwater photos of coral reefs in Florida, 2019
The new structure-from-motion (SfM) quantitative underwater imaging device with five cameras (SQUID-5) was tested in July 2019 at Crocker Reef in the Florida Keys. The SQUID-5 was developed to meet the unique challenges of collecting SfM underwater imagery, including multiple cameras with different perspectives, accurate geographic locations of images, accurate and precise scaling of...
Geophysical and related field data from the West Fork of Dall Creek, AK 2017-2019 Geophysical and related field data from the West Fork of Dall Creek, AK 2017-2019
The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. Multi-season, multi-method geophysical data were collected both within the burned and unburned areas. Geophysical techniques used include Nuculear...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data from Upper Klamath Lake, OR and Upper Klamath River, OR from 4/29 - 10/15/2019 from eight sites and zooplankton data from Upper Klamath Lake, OR from 4/16 - 10/15/2019 from three sites. Phytoplankton data are reported to the lowest possible taxonomic level and biovolume, biomass, and density are reported...
U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2017 - 2018 U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2017 - 2018
The USGS Precipitation Chemistry Quality Assurance Project (PCQA) operates QA programs to challenge and test the National Atmospheric Deposition Program (NADP) data-collection processes for both the National Trends Network (NTN) and Mercury Deposition Network (MDN). PCQA data are available in separate tables for each quality-assurance program: (1) NTN Interlaboratory-comparison, (2) MDN
Volcanic Gas Measurements at Mount Cleveland, Alaska 2016 Volcanic Gas Measurements at Mount Cleveland, Alaska 2016
On 25 July 2016, helicopter-based measurements were made of the volcanic gases emitted from Mount Cleveland, Alaska, USA. An upward-looking differential optical absorption spectroscopy (DOAS) system was used to measure incident scattered solar ultraviolet radiation while traversing beneath the plume on multiple occasions. These data were used to derive volcanic SO2 emission rates...
Geospatial Database of the Study Boundaries, Sampled Sites, Watersheds, and Riparian Zones for the U.S. Geological Survey Regional Stream Quality Assessment Geospatial Database of the Study Boundaries, Sampled Sites, Watersheds, and Riparian Zones for the U.S. Geological Survey Regional Stream Quality Assessment
In 2013, the Regional Stream Quality Assessment (RSQA) study was started as part of the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) project. One of the objectives of the RSQA is to characterize the relationships between water-quality stressors and stream ecology and subsequently determine the relative effects of these stressors on aquatic biota within the...
