Continuous Resistivity Profiling, Electrical Resistivity Tomography and Hydrologic Data Collected in 2017 from Indian River Lagoon, Florida
Researchers from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) in collaboration with USGS Caribbean-Florida Water Science Center (CFWSC) and St. Johns River Water Management District (SJRWMD) investigated spatial variability of bulk resistivity in the Surficial Aquifer located along the Indian River Lagoon (IRL), Florida, USA.

High Microscale Variability in Raman Thermal Maturity Estimates from Shale Organic Matter - Data Release
Here the spatial variation in Raman estimates of thermal maturity within individual organic domains from several shale geologic reference materials originating from the Boquillas, Marcellus, Niobrara, and Woodford Formations are assessed from the respective Raman response. We show that for all four shales the thermal maturity parameters extracted from Raman spectra by iterative peak fitting can va
Major, Minor, and Trace Element Compositions of Bulk Drill Core Samples from the Duluth Complex, Minnesota
This table reports major, minor, and trace element compositions of bulk drill core samples from the Duluth Complex, Minnesota. Major elements were measured using wavelength dispersive X-ray fluorescence (XRF) and inductively coupled plasma atomic emission spectrometry (ICP-AES); minor and trace elements were determined using ICP-AES, inductively coupled plasma mass spectrometry (ICP-MS), and hydri
Water chemistry data for samples collected at groundwater and surface-water sites near the Lost Hills and Belridge oil fields, November 2016-September 2017, Kern County, California
An investigation was done by the U.S. Geological Survey, in cooperation with the California State Water Resources Control Board's Program of Regional Groundwater Monitoring of Water Quality in Areas of Oil and Gas Production, to assess the effects of oil and gas production activities on nearby groundwater resources. During November 2016 September 2017, 30 samples were collected at groundwater well

Data from a Circumpolar Survey on Recreational Activities in Polar Bear Habitat, 2017-2018
These data are the responses of researchers, managers, community members, and tour guides who live or work in polar bear habitats anywhere within their range to inquiries about the types, frequency, and potential impacts of recreational activities. Respondents answered a series of questions on their background and experience with polar bears and the geographic area in which they are familiar. Resp
Baseline Coastal Oblique Aerial Photographs Collected at the U.S. Army Corps of Engineers Field Research Facility, Duck, North Carolina, June 9, 2017
The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms. On June 09, 2017, the USGS conducted an oblique aerial photographic survey of the U.S. Army Corps of Engineers Field Research Facility (USACE FR
Marine ecology near Tufted Puffin colonies across the Aleutian Archipelago and Alaska Peninsula, 2012-2014
In the North Pacific Ocean and Bering Sea between August 2012-2014, data were collected on sea surface temperature and salinity data, marine bird and mammal surveys, hydroacoustic backscatter data, marine environment surrounding Tufted Puffin colonies, and body condition and diets of Tufted Puffin chicks.
Data for modeling tegu lizard distributions in the Americas
This data bundle contains some of the inputs, all of the processing instructions and all outputs from a single VisTrails/SAHM workflow. This model specifically includes field data of thinned occurrence locations and random background locations and un-thinned occurrence locations and targeted background locations for three species of tegu lizards in South America. Predictors included bioclimatic, t
Data for Holocene fault reactivation in the eastern Cascades, WA
Significant uncertainty remains in how and where crustal shortening occurs throughout the eastern Cascade Range in Washington State. Using lidar imagery, we identified a ~5 km long lineament in Swakane canyon near Wenatchee, roughly coincident with a strand of the Entiat fault. Topographic profiles across the lineament reveal a southwest-side-up break in slope with an average of ~3 m of vertical s
Natural Monthly Flow Estimates for the Conterminous United States, 1950-2015
This metadata record describes monthly estimates of natural stream flows for greater than 2.5 million stream reaches, defined by the National Hydrography Dataset (NHD) Version 2.0, in the conterminous United States for the period 1950-2015. A statistical machine learning technique - random forest modeling - was applied to estimate natural flows using 200 potential predictor variables. The dataset
Vibration Monitoring Data from a Bat Hibernaculum at Mammoth Cave National Park, Kentucky, March 2016
The activities associated with the construction of a new walkway within Mammoth Cave caused vibrations to be felt in the cave, which is home to an endangered Indiana bat roost. These data were collected at the request of the National Park Service to monitor the vibration levels near a bat roost within Mammoth Cave National Park to determine if construction-induced vibration might be inducing the o
