Data

Data are estimates of salinity based upon down-core planktic foram assemblages.

The Network for Observation of Volcanic and Atmospheric Change (NOVAC) is a community of volcano observatories and research institutions that together develop and apply ultraviolet differential optical absorption spectroscopy (DOAS) instruments to measure volcanic gas emission rates. The collected data are used for assessment of volcanic activity, eruption forecasting, research on...

The Great Salt Lake (GSL) ecosystem relies on a balanced supply of nutrients to support habitat and industrial uses (Belovsky and others, 2011). To better understand processes controlling GSL nutrient availability, this dataset includes field measurements and laboratory analyses from the water column, sediment, porewater, sediment slurry, brine shrimp, river inflows, sediment traps, and

Examining urban thermal environments has become a critical area of research spanning epidemiology, urban planning, and ecology. While traditional metrics like air temperature (Tair) and satellite-derived surface temperature (SD-LST) dominate urban heat studies, these measures often fail to reflect how people actually experience thermal exposure intensity. More human-oriented metrics...

This data release contains the observed reproductive status and estimated den entrance and emergence data for 114 radio-marked female grizzly bears and the estimated birth dates of offspring for four populations in North America collected from 2011-2021. The studied populations inhabited the Greater Yellowstone Ecosystem, Northern Continental Divide Ecosystem, Selkirk and Cabinet-Yaak...

Suspended-sediment transport is a critical element governing the geomorphology of tidal marshes. Marshes rely both on organic material and inorganic sediment deposition to maintain their elevation relative to sea-level. In wetlands near the Blackwater National Wildlife Refuge, MD, portions of the salt marsh have been subsiding relative to sea level since the early 20th century. Other...

This release presents data from surveys of physical and hydrologic characteristics of the Ohio River streambed and adjacent alluvial aquifer and other related information to document conditions and changes relative to water withdrawals from a series of horizontal, radial collector wells in a riverbank filtration system near Louisville, Kentucky. Surveys were completed by the U.S...

The data includes 1) results of a preliminary pilot study to evaluate six materials for use as benthic mats in open water control of invasive mussels and 2) a definitive study to evaluate the effects of 10-, 20-, and 30-day treatment with plastic and polyvinyl benthic mats on zebra mussel and native juvenile mussel survival and benthic macroinvertebrate diversity and abundance. The study...

This U.S. Geological Survey data release consists of two comma-separated values (CSV) tables containing the results of organic content and radiocarbon dating analyses performed on soil samples collected from a fen in Big Smoky Valley, Nye County, Nevada. Samples were collected from a single soil boring referred to as F1-D on September 11, 2019, using a hand auger. A shapefile of the site...

The Appalachian Basin is an archetypal foreland basin system. However, the timing, rates and magnitudes of orogenic loading, fold-thrust belt (FTB) exhumation, and foreland basin burial and exhumation are not well constrained. Here, we present vitrinite reflectance data, alongside organic geochemical screening analysis (programmed pyrolysis and total organic carbon) from a ~350 km...

The Ordovician Icebox Formation of the Winnipeg Group has been interpreted as a petroleum source rock within the Williston Basin for over 50 years. Despite limited hydrocarbon production from Winnipeg Group reservoirs and being deeply buried (located below most of the current hydrocarbon producing reservoirs), the petroleum industry continues to periodically drill wells through the...

Double-crested cormorant (Phalacrocorax auritus) fresh eggs and sibling embryos at pipping were collected from a polychlorinated biphenyl (PCB)- contaminated colony in Green Bay, Wisconsin, USA. Egg contents were analyzed for organochlorine (OC) contaminants, including 15 aryl hydrocarbon-active PCB congeners. Concentrations of 20 organochlorine contaminants present in double-crested...
