Nearshore bathymetry of the Columbia River littoral cell, Washington and Oregon, 2021

This portion of the USGS data release presents bathymetry data collected during surveys performed in the Columbia River littoral cell, Washington and Oregon, in 2021 (USGS Field Activity Number 2021-632-FA). Bathymetry data were collected using four personal watercraft (PWCs) equipped with single-beam sonar systems and global navigation satellite system (GNSS) receivers. The sonar systems consisted of an Odom Echotrac CV-100 single-beam echosounder and 200 kHz transducer with a 9-degree beam angle. Raw acoustic backscatter returns were digitized by the echosounder with a vertical resolution of 1.25 cm. Depths from the echosounders were computed using sound velocity profiles measured using a YSI CastAway CTD during the survey. Positioning of the survey vessels was determined at 5 to 10 Hz using Trimble R7 GNSS receivers. Output from the GNSS receivers and sonar systems were combined in real time on the PWC by a computer running HYPACK hydrographic survey software. Navigation information was displayed on a video monitor, allowing PWC operators to navigate along survey lines at speeds of 2 to 3 m/s. Survey-grade positions of the PWCs were achieved with a single-base station and differential post-processing. Positioning data from the GNSS receivers were post-processed using Waypoint Grafnav to apply differential corrections from a GNSS base station with known horizontal and vertical coordinates relative to the North American Datum of 1983. Orthometric elevations relative to the NAVD88 vertical datum were computed using National Geodetic Survey Geoid12a offsets. Bathymetric data were merged with post-processed positioning data and spurious soundings were removed using a custom Graphical User Interface (GUI) programmed with the computer program MATLAB. The average estimated vertical uncertainty of the bathymetric measurements is 10 cm. The final point data from the PWCs are provided in a comma-separated text file and are projected in cartesian coordinates using the Washington State Plane South, meters coordinate system.

Voucher and metagenetic sequencing of DNA barcodes of wild-collected bees (Apoidea) from Iowa, USA

High-throughput methods for identification of pollinator taxa are desirable to improve our understanding of pollinator distributions, population trends, and ecology. Genetic sequencing of taxonomically informative 'barcode' loci is one high-throughput strategy, which can be applied to individual specimens using Sanger technology and to complex mixtures using metabarcoding technology. This study generated Sanger sequencing data from morphologically identified specimens and metabarcoding data derived from pooled tissues.
This data release consists of several files:
1. sample.metadata.txt, which contains sampling metadata and identifiers linking to sequence data that has been deposited in the Sequence Read Archive of the National Center for Biotechnology Information (NCBI). This database is authoritative and comprehensive for sharing high-throughput sequence data produced with public funds. All NCBI-derived accessions listed in the file can be searched at www.ncbi.nlm.nih.gov to retrieve sample and sequence information 
2. raw.counts.txt, which is a tab-delimited table of counts of individual metabarcode sequences that are attributed to each detected bee genus.
3. BeeSangerSequencesFASTA.txt, which is a text document in FASTA format containing the DNA sequences obtained from the individual specimens using Sanger sequencing technology.
4. reference.sequences.fasta, which is a text document in FASTA format containing the DNA sequences obtained from public databases for taxonomic assignment of metabarcode sequences as described in the process steps.

X-radiographs of sediment cores from the Currituck Landslide Complex and upper slope adjacent to Baltimore Canyon collected on USGS Field Activity 2012-007-FA

Twenty-four piston cores (and associated trigger cores) were collected from the source zone of the Currituck Landslide Complex and upper slope adjacent to Baltimore Canyon by the U.S. Geological Survey and the University of Rhode Island Department of Ocean Engineering during an eight-day cruise aboard the R/V Hugh R. Sharp in September/October of 2012. These cores were analyzed for evidence of seafloor mass transport processes, with an emphasis on constraining the age and shallow stratigraphy of the landslide complex. Sedimentological and geotechnical characterization of the cores was carried out through whole core imaging and description, followed by analysis of discrete samples at the USGS Woods Hole Coastal and Marine Science Center's Sediment Analysis Laboratory and other facilities, including grain-size, CaCO3 content, mineral composition, and bulk index properties (e.g., undrained shear strength and water content), micropaleontologic separations, and geochronology. This data release contains the results of these core descriptions and results of the laboratory analyses.

Lake Erie Collaborative Science and Monitoring Initiative 2014

In 2014, the USGS Lake Erie Biological Station participated in the Coordinated Science and Monitoring Initiative (CMSI) program, a program founded by the U.S. Environmental Protection Agency (EPA) and Environment Canada in the 1990s as a means to focus collaborative research attention on one of the five Great Lakes each year (on a rotating schedule) as a means to increase scientific knowledge for Great Lakes restoration.  The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013).  We sampled all trophic levels in all three lake basins across multiple seasons in order to determine nutrient availability and trophic energy transfers from nearshore to offshore across the lake’s west-east production gradient.  In each basin two transects, each consisting of replicate nearshore, mid, and offshore sites were sampled.   The lower trophic food web (water nutrients, zooplankton, and benthos) was sampled monthly, and the fish community (via bottom trawl and hydroacoutics) was sampled bi-monthly (May, July, and September).  By examining the trophic interactions and energy transfer in all three basins, this data may be of interest to anyone interested in examining some of Lake Erie’s principal environmental and ecological issues such as sedimentation and nutrient loading (western basin), seasonal hypoxia (central basin), and strong nearshore to offshore production gradients (eastern basin).

Lower Rio Puerco 2005 georeferenced aerial photographs

High-resolution (0.20 m) digital images collected during an aerial LiDAR survey of the Lower Rio Puerco during April and July 2005. Details on data collection and processing methods are provided in an unpublished report by Spectrum Mapping, LLC (August 2005; see Supplemental Information). The images are Spectral Imagery LiDAR Composite (SILC) in which individual image pixels have been associated with individual xyz values to improve feature discrimination, including bare earth surfaces, as well as quality control processing. Stated horizontal and vertical accuracies are &lt;0.30 m rms error in x, y, and z. This image set has been modified from the original by clipping large areas of no data (white space) from the outer edges to reduce file size. These images have the highest resolution and greatest accuracy of the Lower Rio Puerco imagery collection. Geomorphic parameters derived from mapping from these images were presented in the following publications:

Multichannel seismic-reflection data acquired off the coast of southern California - Part A 1997, 1998, 1999, and 2000

Multichannel seismic-reflection (MCS) data were collected in the California Continental
Borderland as part of southern California Earthquake Hazards Task. Five data acquisition
cruises conducted over a six-year span collected MCS data from offshore Santa Barbara,
California south to the Exclusive Economic Zone boundary with Mexico. The primary mission
was to map late Quaternary deformation as well as identify and characterize fault zones that
have potential to impact high population areas of southern California. To meet its objectives,
the project work focused on the distribution, character, and relative intensity of active
(i.e., Holocene) deformation along the continental shelf and basins adjacent to the most highly
populated areas. In addition, the project examined the Pliocene-Pleistocene record of how
deformation shifted in space and time to help identify actively deforming structures that
may constitute current significant seismic hazards.
The MCS data accessible through this report cover the first four years of survey activity and
include data from offshore Malibu coastal area west of Santa Monica, California to the southern
survey limit offshore San Diego. The MCS data, which were collected with a 250-m-long, 24-channel
streamer used a small gas-injector airgun source. This system provided optimum resolution of
the upper 1 to 2 km of sediment for mapping active fault systems. The report includes trackline
maps showing the location of the data, as well as both digital data files (SEG-Y) and images
of all of the profiles.
These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.

Spatial patterns of dewatering within watersheds of Shenandoah National Park, Virginia (2016 and 2019)

These data describe longitudinal (upstream to downstream) patterns of dewatering during summer baseflow (July-September) conditions in nine watersheds in Shenandoah National park. In July-August of 2016 all nine watersheds (Jeremy's Run, Hazel River, Piney River, Hughes River, Staunton River, Whiteoak Canyon Run, Paine Run, Meadow Run, and Big Run) were evaluated for dewatering. In September of 2019, dewatering surveys were repeated in three watersheds (Pine Run, Piney River, and Staunton River) to evaluate annual variation in dewatering patterns. Data were collected by team of investigators walking each stream from an upstream point defined by the point along the stream draining 75-hectares (determined using watershed tools in ArcGIS Pro, version 2.6.0) to the bottom of each watershed near the park boundary, and mapping transition points between three hydrologic categories: Wet, dry, or isolated pools based upon investigator observation. “Wet” segments were defined as reaches where entire channel was wet with flow between pools; “Dry” segments were defined as reaches containing no water, or water of insufficient depth to sustain age 1+ brook trout; and “Isolated Pools” were defined as reaches containing pools of sufficient depth to hold 1+ brook trout but these pools were hydrologically disconnected from other parts of the channel. Because "Isolated Pool" type contains components of other two drying types (i.e., wet and dry), the boundaries were determined by the first transition/change encountered in the downstream direction of assessment. For example, when transitioning from a wet reach to isolated pools, the transition point marking the upstream boundary of the "isolated pool" would be the first dry segment encountered. Similarly, when transitioning from dry reach to isolated pool, the first encounter of a wet section would mark the upstream boundary of the isolated pool. Spatial coordinates of transition points were mapped using a Trimble R2 GNSS receiver for &lt;1-meter accuracy.
