Data

These data along with continuous monitoring at several locations (data provided through NWIS) are used to monitor bottom salinity and tidal currents associated with a project to better monitor X2 (position of 2 PSU [Practical Salinity Units] isohaline) in the lower Sacramento River and Suisun Bay, CA. Links to NWIS sites are provided in the associated web links under 'Related External...

R code to analyze these data to estimate proportion of hens with poults and poults per brood, and estimate temporal trends in proportion of hens with poults is available at https://doi.org/10.5066/P14VYTVN. The state wildlife agencies in Maryland, New Jersey, New York, Ohio, Pennsylvania, Virginia, and West Virginia collected observations of wild turkeys during June-August, 2000-2023...

Samples of the Mauna Loa 2022 eruption were collected throughout the 15 days of the eruption, and from all eruptive vents, by the U.S. Geological Survey. Emphasis was placed on obtaining water-quenched flow samples, spatter and volcanic bombs wherever possible. This was not possible for the early Moku‘āweoweo, Southwest Rift Zone and upper Northeast Rift Zone vents which erupted during...

Acalolepta aesthetica (Coleoptera: Cerambycidae) is a beetle species whose larvae develop within branches and stems of host plants and can harm or kill host trees. Since this species was detected on the Island of Hawai'i in 2009, it has been documented to have a wide host breadth but its host preferences and its potential to use native plant species as hosts have not been formally...

This data set contains toxicity data from 24- and 96-hour water bioassays to assess the effects of a Syngenta Crop Protection product on early life stages of a freshwater mussel. We used ASTM International methods to conduct tests with juveniles and glochidia of the freshwater mussel Lampsilis siliquoidea. Analytical chemistry and water quality analysis results are included as well.

This data release documents sixteen 5-year simulations using the USGS SUTRA groundwater flow modeling software and includes the full output from one 5-year simulation for verification that the model code runs properly. The most recent version of SUTRA (version 4.0) was used to evaluate aquifer (ATES) and reservoir (RTES) thermal energy storage performance to support economic analyses by...

Two laboratory experiments were conducted to understand PFOS (perfluorooctanesulfonic acid) bioaccumulation in freshwater benthic diatoms (Mayamaea atomus). The first experiment tested bioconcentration at multiple PFOS concentrations (0, 0.01, 0.1, 1, 10, 100 micrograms per liter) after 7 days of exposure. The second explored uptake and depuration of 0.1 micrograms per liter PFOS at...

This data release includes vertical water-quality profile data collected from April 2022 to April 2024 at three locations in the Saugatuck River Embayment near Saugatuck, Connecticut, and two locations in the Mill River and one at the mouth of Sasco Brook near Southport Harbor, Connecticut, for the Sasco-Southport Embayment that discharge to Long Island Sound. These data were collected...

The USGS team measured base cations, aluminum (Al), iron (Fe), manganese (Mn), rare earth elements (REEs), dissolved organic carbon (DOC), major anions, and phosphorus (P) in eight streamwater grab (manual) samples during each of three high-flow events (E-1, E-2, E-3) at the forested headwater catchment W-9, Sleepers River, Vermont, USA. E-1 was a large fall rainstorm, E-2 was a multi...

Multiple generations of spring-fed streams traversed ~800 km2 of the Las Vegas Valley in southern Nevada between ~10.9 and 8.5 ka, depositing an extensive tufa network. The scale of this network and diversity of tufa morphologies is novel in North America and offers an opportunity to obtain quantitative paleoclimate data for the region during the early Holocene. We determined isotopic...

This data release includes tabular summaries of specific conductance, temperature, and altitude (depth; CTD) and plots of specific conductance versus altitude at selected groundwater monitoring wells during July 2018–July 2024. The tabular summaries were developed using data retrieved from GeoLog Locator, an online database for quality-assured borehole geophysical data and accessible at...

We simulated a 3-hour, 1-km spatially seamless surface soil moisture (SSM) dataset (called STF_SSM) in the Contiguous United States (CONUS) using a virtual image pair-based spatio-temporal fusion method. This proposed approach effectively fuses the distinct advantages of two long-term SSM datasets, namely, the Soil Moisture Active Passive (SMAP) L4 SSM product and the Crop Condition and...
