Dissolved noble gas data and helium mass balance models for the Colorado and Virgin Rivers Dissolved noble gas data and helium mass balance models for the Colorado and Virgin Rivers
Dissolved noble gas data were collected using a portable mass spectrometer mounted on inflatable rafts on the Colorado River near Glenwood Springs, Colorado and the Virgin River near La Verkin, Utah. Data were collected approximately every 3 to 10 minutes for a suite of noble gases including helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe). Patterns in observed dissolved...
Dissolved oxygen predictions for releases from Lake Powell under different management scenarios for Lake Powell releases Dissolved oxygen predictions for releases from Lake Powell under different management scenarios for Lake Powell releases
Dissolved oxygen estimates were generated to help understand how different alternative management scenarios may affect the likelihood of low dissolved oxygen in Glen Canyon Dam releases. The study aimed to examine the effects of different management alternatives on late summer and early fall dissolved oxygen concentrations in Glen Canyon Dam releases. The estimates represent estimates of...
DNA sequences used to analyze evolutionary rates of genes in bats DNA sequences used to analyze evolutionary rates of genes in bats
The dataset consists of sets of orthologous gene sequences obtained from the National Center for Biotechnology Information (NCBI, www.ncbi.nlm.nih.gov) and from Cornman and Cryan (2022). Sequences derive from twelve bat species that are representative of bat diversity and for which high-quality gene models have been annotated. Each gene set was codon aligned and subsequently trimmed as...
Down Selected Artemis III Candidate Landing Site Navigational Grids Down Selected Artemis III Candidate Landing Site Navigational Grids
USGS is assessing the feasibility of map projections and grid systems for lunar surface operations. We propose developing a new Lunar Transverse Mercator (LTM), the Lunar Polar Stereographic (LPS), and the Lunar Grid Reference Systems (LGRS). We have also designed additional grids designed to NASA requirements for astronaut navigation, referred to as LGRS in Artemis Condensed Coordinates...
Down-looking camera images of round goby (Neogobius melanostomus) within constructed sand and cobble habitats in laboratory microcosms Nov. 2021 – Jan. 2022 Down-looking camera images of round goby (Neogobius melanostomus) within constructed sand and cobble habitats in laboratory microcosms Nov. 2021 – Jan. 2022
These data include down-looking images of round goby (Neogobius melanostomus) in either cobble or sand substrates within clear acrylic enclosures (0.86-meters (m) long, by 0.56-m wide, by 1.07-m high). Ten individual round goby were added to enclosures for imaging to ensure known abundances in each tank. Images were collected to evaluate the efficiency of image-based methodologies for...
Down-looking Images of Lake Trout (Salvelinus namaycush) and Round Goby (Neogobius melanostomus) to Support Automated Biomass Estimation Down-looking Images of Lake Trout (Salvelinus namaycush) and Round Goby (Neogobius melanostomus) to Support Automated Biomass Estimation
These data include in situ images of lake trout (Salvelinus namaycush) and round goby (Neogobius melanostomus) collected by an autonomous underwater vehicle (AUV) in Lakes Michigan and Superior in 2020 and 2021 and laboratory images of round goby collected by a GoPro in 2021. These images were collected and labeled to train and validate an algorithm for automated fish sizing and biomass...
Downscaled Climate Projections for the Edwards Aquifer Region (EAR) using CMIP5 for the years 2006 – 2010 and CMIP6 for the years 2015 - 2010 Downscaled Climate Projections for the Edwards Aquifer Region (EAR) using CMIP5 for the years 2006 – 2010 and CMIP6 for the years 2015 - 2010
Global climate models (GCMs) are computationally intensive, physics-based research tools used to simulate the climate system. GCM can also be useful in applied research contexts with the use of statistical downscaling techniques. This collection of statistically downscaled climate projections includes 7 sets of SD-processed CMIP5 projections and 12 sets of SD-processed CMIP6 projections...
Drainage network for the Greater Raleigh Area, North Carolina, 2015-2022 Drainage network for the Greater Raleigh Area, North Carolina, 2015-2022
As part of a collaborative study with the City of Raleigh, North Carolina, the U.S. Geological Survey developed a drainage network for the Greater Raleigh Area, North Carolina using the most recent available lidar data, representing the years 2015 and 2022. This dataset includes the delineated drainage network (drainage_network.zip) and rasters representing the breached and filled...
Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020) Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020)
Indicators of climatic, hydrologic, and ecological drought responses in water-related terrestrial and aquatic conditions within a single catchment in the northwestern Great Basin Desert and its associated stream network were developed from stream flow, climate and remote sensing sources for the time period of 1988 to 2020.
Duckling Survival in a Brackish Marsh Duckling Survival in a Brackish Marsh
We conducted a multi-year study (2016-2019) to quantify sources of duckling mortality, identify predator type, and estimate survival rates for Mallard (Anas platyrhynchos) and Gadwall (Mareca strepera) ducklings within Suisun Marsh, California.
