Standard deviation of the bathymetric DEM of the Sacramento River, from the Feather River to Knights Landing, California in February 2011

This part of the data release contains a grid of standard deviations of bathymetric soundings within each 0.5 m x 0.5 m grid cell.  The bathymetry was collected on February 1, 2011, in the Sacramento River from the confluence of the Feather River to Knights Landing. The standard deviations  represent one component of bathymetric uncertainty in the final digital elevation model (DEM), which is also available in this data release. The bathymetry data were collected by the USGS Pacific Coastal and Marine Science Center (PCMSC) team with collaboration and funding from the U.S. Army Corps of Engineers. This project used interferometric sidescan sonar to characterize the riverbed and channel banks along a 12 mile reach of the Sacramento River near the town of Knights Landing, California (River Mile 79 through River Mile 91) to aid in the understanding of fish response to the creation of safe habitat associated with levee restoration efforts in two 1.5 mile reaches of the Sacramento River between River Mile 80 and 86.

Spectral data for discrete surface water samples from the Sacramento-San Joaquin River Delta

The goal of this study was to develop a suite of inter-related water quality monitoring approaches capable of modeling and estimating the spatial and temporal gradients of particulate and dissolved total mercury (THg) concentration, and particulate and dissolved methyl mercury (MeHg), concentration, in surface waters across the Sacramento / San Joaquin River Delta (SSJRD). This suite of monitoring approaches included: a) data collection at fixed continuous monitoring stations (CMS) outfitted with in-situ sensors, b) spatial mapping using boat-mounted flow-through sensors, and c) satellite-based remote sensing. The focus of this specific Child Page is to present laboratory measured spectral data associated with discrete surface water samples collected as part of both the CMS and boat mapping sampling efforts.  
All laboratory-based measurement presented herein were conducted by the U.S. Geological Survey (USGS) Organic Matter Research Laboratory (OMRL) in Sacramento, Calif. The machine-readable (comma separated value, *.csv) files presented herein include spectral data collected using two different instruments: 1) Laboratory-based absorbance and fluorescence measurements on filtered water using an Aqualog (Hansen and others, 2018) and 2) Laboratory-based absorption measurements using a Varian Cary spectrophotometer on particulate samples collected on glass fiber filters (Kishino and others, 1985; Roesler, 1998). The reported spectral data includes: 1) fluorescence intensities across a wide range of excitation (240 to 800 nm) and emission (250 to 800 nm) wavelengths expressed as an excitation-emission matrix (EEM), 2) absorbance of light (from 239 nm to 800 nm) due to dissolved and colloidal substances, and 3) absorption coefficients (from 350 nm to 715 nm) for particulates using the quantitative filter technique (QFT).

Hawaiian hoary bat acoustic data pre- and post- koa moth outbreak, Hawaii Island, 2011-2013

We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lāupahoehoe Forest Reserve on Hawai‘i Island during the 2013 koa moth (Geometridea: Scotorythra paludicola) outbreak. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level, that operated nightly from May 2013 through September 2013. We compared these data to data collected at similar locations in 2011 to determine the response of bats to increased moth abundance during 2013. This data set includes data derived from these acoustic recording stations. Each acoustic recording station was comprised of an acoustic recording unit (Anabat SD1, Titely Scientific, Ballina, Australia) programmed to record from 1700 to 0500 each recording night. Each recording unit was deployed in a waterproof housing and powered by a 12 V external battery. An ultrasonic Hi-Mic microphone was mounted inside PVC pipe oriented toward the ground to prevent rain damage. A 15 x 15 cm plexiglass plate was attached below the microphone at a 45-degree angle to reflect and enhance calls from bats flying above the microphone. The PVC and microphone were affixed to the top of a 7- meter steel pole. Anabat Hi-Mics in this configuration have an omnidirectional maximum effective range of 30 meters. Upon detection of a vocalizing bat  a call file was stored with the corresponding date and time on a compact flash (CF) memory card. Memory cards and batteries were replaced every 1-2 weeks during which quality checks on equipment were made. 
In this abstract we refer to the Hawaiian hoary bat as a full species, Lasiurus semotus, following updated taxonomy for Hawaiian hoary bats (Pinzari et al. 2020; see full citation below in the cross-references section).

Surface-water-altitude data, from streamgages, considered for the potentiometric-surface map, Mississippi River Valley alluvial aquifer, spring 2020

This dataset contains surface-water-altitude (SWA) data from streamgages that were used or considered (indicated by the field USE_2020) to create a potentiometric-surface map for the Mississippi River Valley alluvial aquifer (MRVA) for spring 2020. The SWA data was referenced to the North American Vertical Datum of 1988 (NAVD 88). The streamgages are measured continuously. The streamgage measurement that was used was from early April 2020 and is an estimate of the groundwater altitudes (GWAs) at the gage location. The resultant potentiometric-surface contours and raster represents the generalized central tendency for spring 2020, but it would not be useful for some purposes, such as for calibration of a groundwater-flow model for early April 2020 or for some local scale assessments.

Groundwater-altitude data, from monitoring-networks wells, considered for the potentiometric-surface map, Mississippi River Valley alluvial aquifer, spring 2020

This dataset contains groundwater-altitude (GWA) data from wells that were used or considered (indicated by the field USE_2020) to create a potentiometric-surface map for the Mississippi River Valley alluvial aquifer (MRVA) for spring 2020. The GWA data was referenced to the North American Vertical Datum of 1988 (NAVD 88). Most of the wells were measured annually, but some wells were measured more than one time in a year and a small number of wells were measured continuously. GWA data were from wells measured in spring 2020. To best reflect hydrologic conditions in the MRVA, the GWA data used to create the 2020 potentiometric surface would be measured in a short-time frame of days or a week and there would be available data (for example from sets of wells with short-screen (about 5 to 10 feet or 1.5 to 3 meters) installed near the top, in the middle, and near the bottom of the aquifer) to indicate vertical flow components. However, most wells screened in the MRVA were measured before the potentiometric-surface map of the MRVA was planned and therefore the timing of each well's measurement(s) was determined by the needs and schedules of the entities doing the measurements. Also, many of the measured wells had longer screens (from greater than 10 feet or 3 meters and covering a substantial part of the aquifer thickness), therefore their water-level measurements represent an average head in the aquifer for that location. The resultant potentiometric-surface contours and raster represents the generalized central tendency for spring 2020, but it would not be useful for some purposes, such as for calibration of a groundwater-flow model for early April 2020 or for some local scale assessments.

Spatial dataset of the potentiometric-surface contours, Mississippi River Valley alluvial aquifer, spring 2020, in feet

This dataset contains the contours, in feet, of the potentiometric-surface, spring 2020, Mississippi River Valley alluvial aquifer (MRVA). The contours are referenced to the North American Vertical Datum of 1988 (NAVD 88). The contours were derived from most of the available groundwater-altitude (GWA) data from wells and surface-water-altitude (SWA) data from streamgages, measured in for spring 2020. The potentiometric contours ranged from 10 to 340 feet (3 to 104 meters) above NAVD 88. The regional direction of groundwater flow was generally towards the south-southwest, except in areas of groundwater-altitude depressions, where groundwater flows into the depressions, and near rivers, where groundwater flow generally parallels the flow in the rivers.

Airborne magnetic and radiometric survey, Charleston, South Carolina and surrounds, 2019

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Charleston, South Carolina and the surrounding region. These data were collected to better understand earthquake hazards in the Charleston seismic zone by imaging structural features in the crystalline basement and to image heavy mineral sands containing titanium, zirconium, and rare earth elements using radiometric data (gamma spectrometry), which is sensitive to thorium in monazite. This survey represents a collaborative effort by the U.S. Geological Survey (USGS) Earthquake Hazards Program, Mineral Resources Program, National Cooperative Mapping Program, and Earth Mapping Resource Initiative (Earth MRI) effort.
Data for this survey were collected by Terraquest, Ltd. under contract with the USGS using a fixed wing aircraft with magnetometers mounted in the tail stinger and each wing tip pod and a fully calibrated gamma ray spectrometer from May to July of 2019. The survey covers a 134-kilometer x 90-kilometer rectangular area parallel to the Atlantic Ocean shoreline along the long axis. Data were collected along northwest-southeast flight lines spaced 400 meters (m) apart with northeast-southwest tie lines flown every 4000 m. A mean terrain clearance of 127 m was maintained. Most of the survey data were collected at lower flying heights, except near and over the City of Charleston higher clearance was maintained due to safety considerations. A total of 32,447-line kilometers (km) of data were collected.
Files that are available in this publication include flight line data for the magnetic survey in an ascii .csv file, flight line data for the radiometric survey in an ascii .csv file, geoTIFF images of the total magnetic intensity and radiometric total count, potassium, thorium, and uranium values, and a report describing the survey parameters, field operations, quality control and data reduction procedures. A zip file containing the contractor's deliverable products is also included. Binary files in this package are readable using the free software "Geosoft Viewer" or commercial software "Oasis Montaj."
