Attributions for nonstationary peak streamflow records in the Northeast region, 1941-2015 and 1966-2015, and supporting information A comma separated values (csv) file of data used to support attribution of trends and change points in annual peak streamflows observed at gages in the Northeast region. The file includes USGS gage identification and location information, developed land cover and basin storage data, correlation results between annual peak magnitudes and precipitation and Palmer Drought Severity Index (PDSI), and trend and change point results for precipitation and PDSI.

This project is supported in part by funding from the USGS NGGDPP which aims to convert historical paper geologic reports and maps into digital formats, among other data preservation activities. This report was chosen because of its proximity to the Mountain Pass Rare Earth Element Mine and ongoing mapping by the CGS as part of an EarthMRI funded project in the New York Mountains.

A systemic data collection for the Upper Mississippi River System (UMRS) was completed in 2010. Water depth in aquatic systems is important for describing the physical characteristics of a river. Bathymetric maps are used for conducting spatial inventories of the aquatic habitat and detecting bed and elevation changes due to sedimentation. Bathymetric data is widely used, specifically for studies of water level management alternatives, modeling navigation impacts and hydraulic conditions, and environmental...

We programmed the recorder to sample for five minutes at the top of every hour of every day from late winter/early spring through late summer. We used the Songscape option in Songscope software to generate annual summaries of all of our acoustic samples from SC4DAI2.

We conducted 10 minute 50m fixed radius point counts (Ralph et al. 1993) to survey birds during the breeding period between 30 May and 10 July in all years. We sampled the southernmost pool (13) first and then progressed to each pool in succession northward, finishing in Pool 4, sampling each point once a season. Surveys were conducted from 30 minutes before to five hours after local sunrise....

Abstract from manuscript: Knowledge of environments used during early life history and movement patterns of Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix), collectively termed bigheaded carps, in the Upper Mississippi River (UMR) would be valuable for informing control measures to limit further population expansion and impacts of these species.

ERT surveys were done at four locations in May through June of 2018 to refine the understanding of the bedrock-alluvial aquifer transition zone downgradient from the AFRL. The ERT technique injects direct-current electricity with known voltage and current into the earth using a series of electrodes and measures the resulting resistivity. This technique is generally limited to investigations of aquifer properties less than 100 meters below land surface. Data from other geophysical techniques co-located with the ERT data, including time-domain electromagnetics and horizontal-to-vertical...

TEM surveys were done at 33 locations between May and October 2018 to refine the understanding of the bedrock-alluvial aquifer transition zone downgradient from the AFRL. TEM surveys (also called transient electromagnetic surveys) provide 1D resistivity soundings of the subsurface, which can be related to lithology and hydrogeology. In the TEM method, electrical current is cycled through a transmitter loop (Tx) wire, which in turn produces a primary magnetic field. When the current is abruptly terminated, a secondary magnetic field is induced in the earth, and it moves downward and...

Orphaned mineral mine sites are those that were never permitted in the state of Virginia. In 1978, the Surface Mining Control and Reclamation Act (SMCRA) required operatrors to obtain a permit to operate a mineral mine site in Virginia. Mineral mines are considered any mine that is non-coal. Office of Surface Mining Reclamation and Enforcement (OSMRE), through its Abandoned Mine Land (AML) Reclamation Program, addresses the hazards and environmental degradation posed by these legacy coal mine sites.

Williams Well Sample Library and maintains well cuttings and core samples as a permanent record of rock strata that have been penetrated by wells drilled in Arkansas. Driller logs housed at the Survey contain the down hole information about the geology in the state. Each log gives the depth in feet along with the discription of material being drilled and the depth it accurs. The logs cover wells drilled in the early 1900’s to 1950’s and dispersed throughout the state giving statewide subsurface information.
