Thiamine concentrations in lake trout eggs collected from the Great Lakes in 2019-20 Thiamine concentrations in lake trout eggs collected from the Great Lakes in 2019-20
Text files containing data regarding attributes of lake trout egg thiamine concentrations from sites in lakes Huron and Michigan collected during 2019-20, sampling site locations and quality assurance quality control values for comparison to previous years (2017-18) lake trout egg thiamine concentrations.
U-Pb age determinations of uraninite by electron microprobe analyses of ore samples from two solution-collapse breccia pipe uranium deposits, Grand Canyon region, northwest Arizona, USA U-Pb age determinations of uraninite by electron microprobe analyses of ore samples from two solution-collapse breccia pipe uranium deposits, Grand Canyon region, northwest Arizona, USA
This data release compiles the electron microprobe spot analyses of U, Th, and Pb concentrations in uraninite (U oxide) particles, and corresponding calculated age determinations, measured in samples of ore from two uranium-copper breccia pipe ore bodies, the Canyon (Pinyon Plain) and Hack II deposits. The U-rich samples that were analyzed typify the deposits hosted by solution-collapse...
Water column physical and chemical properties of Cenote Bang, a component of the Ox Bel Ha cave network within the subterranean estuary coastal aquifer of the Yucatan Peninsula, from December 2013 to January 2016 Water column physical and chemical properties of Cenote Bang, a component of the Ox Bel Ha cave network within the subterranean estuary coastal aquifer of the Yucatan Peninsula, from December 2013 to January 2016
Subterranean estuaries extend inland into density-stratified coastal carbonate aquifers that contain a surprising diversity of endemic animals (mostly crustaceans) within a highly oligotrophic environment. How complex ecosystems thrive in this globally-distributed, cryptic habitat (termed anchialine) is poorly understood. The northeastern margin of the Yucatan Peninsula contains over 250...
Hydrologic and Water Quality Data from the Cedar River and Cedar River Alluvial Aquifer, Linn County, Iowa, 1990-2019 Hydrologic and Water Quality Data from the Cedar River and Cedar River Alluvial Aquifer, Linn County, Iowa, 1990-2019
Surface and groundwater samples were collected, processed, and analyzed for pesticides, nutrients, organic carbon, and inorganics as part of a cooperative study with the City of Cedar Rapids, Iowa. Filtered and whole water samples were sent to the National Water Quality Laboratory in Denver, Colorado. U.S. Geological Survey staff collected field properties and discharge measurements in...
Microbial Community Composition Data from Blacktail Creek near Williston, North Dakota Microbial Community Composition Data from Blacktail Creek near Williston, North Dakota
A large spill of wastewater from oil and gas operations was discovered adjacent to Blacktail Creek near Williston, North Dakota in January 2015. To determine the effects of this spill on streambed microbial communities over time, bed sediment samples were taken from Blacktail Creek upstream, adjacent to, and at several locations downstream from the spill site. Blacktail Creek is a...
Unvegetated to vegetated marsh ratio in Assateague Island National Seashore and Chincoteague Bay, Maryland and Virginia Unvegetated to vegetated marsh ratio in Assateague Island National Seashore and Chincoteague Bay, Maryland and Virginia
Unvegetated to vegetated marsh ratio (UVVR) in the Assateague Island National Seashore and Chincoteague Bay is computed based on conceptual marsh units defined by Defne and Ganju (2018). UVVR was calculated based on U.S. Department of Agriculture National Agriculture Imagery Program (NAIP) 1-meter resolution imagery. Through scientific efforts initiated with the Hurricane Sandy Science...
Table and accompanying photographs for biogeomorphic classification of shorebird nesting sites on the U.S. Atlantic coast from March to September, 2016 Table and accompanying photographs for biogeomorphic classification of shorebird nesting sites on the U.S. Atlantic coast from March to September, 2016
Atlantic coast piping plover (Charadrius melodus) nest sites are typically found on low-lying beach and dune systems, which respond rapidly to coastal processes like sediment overwash, inlet formation, and island migration that are sensitive to climate-related changes in storminess and the rate of sea-level rise. Data were obtained to understand piping plover habitat distribution and use...
Collections Inventory for the U.S. Geological Survey Woods Hole Coastal and Marine Science Center Samples Repository (ver. 2.0, September 2023) Collections Inventory for the U.S. Geological Survey Woods Hole Coastal and Marine Science Center Samples Repository (ver. 2.0, September 2023)
The collections inventory database for the U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center (WHCMSC) Samples Repository is published as a USGS data release (Buczkowski and others, 2018), and is available to search online through the Samples Repository inventory search interface. Sample collections in the Repository can be searched and selected through a map...
Viral-like particles are associated with endosymbiont pathology in Florida corals affected by stony coral tissue loss disease Viral-like particles are associated with endosymbiont pathology in Florida corals affected by stony coral tissue loss disease
Stony coral tissue loss disease (SCTLD) was first documented in 2014 near the Port of Miami, Florida, and has since spread north and south along Florida's Coral Reef, killing large numbers of more than 20 species of coral and leading to the functional extinction of at least one species, Dendrogyra cylindrus. SCTLD is assumed to be caused by bacteria based on presence of different...
Data Release for Reconstructing paleohydrology in the northwest Great Basin since the last deglaciation using Paisley Caves fish remains (Oregon, U.S.A.) Data Release for Reconstructing paleohydrology in the northwest Great Basin since the last deglaciation using Paisley Caves fish remains (Oregon, U.S.A.)
This dataset includes tables of stratigraphic age-depth information for Paisley Caves 2 and 5, in Oregon U.S.A., along with tables of fish bone abundance and stable and strontium isotopic data for fish remains and geological samples from the study area surrounding the Paisley Caves.
Water-quality data for a statewide assessment of per- and polyfluoroalkyl substances (PFAS) study in Iowa, 2019-2020 Water-quality data for a statewide assessment of per- and polyfluoroalkyl substances (PFAS) study in Iowa, 2019-2020
Data were collected at 60 surface water and two effluent sites across Iowa in 2019-2020 by staff from the U.S. Geological Survey Central Midwest Water Science Center. Samples were submitted to the National Water Quality Laboratory in Denver, Colorado, and were analyzed for per- and polyfluoroalkyl substances.
Sea-Floor Sediment Samples, Seabed Imagery, and CTD Instrument Data Collected on Stellwagen Bank in September, 2014, U.S. Geological Survey Field Activity 2014-055-FA Sea-Floor Sediment Samples, Seabed Imagery, and CTD Instrument Data Collected on Stellwagen Bank in September, 2014, U.S. Geological Survey Field Activity 2014-055-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...
