Surveys and monitoring of coastal cactus wren in San Diego County, 2022

Data presented are results of surveys and monitoring for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. These data were collected to assess Cactus Wren population status to determine the relationships between specific elements of habitat quality and Cactus Wren presence. Surveys were conducted periodically at 507 plots throughout San Diego County. Birds that had been banded in prior years with unique color combinations were identified to individual on subsequent visits to provide data on survival and movement between years.

Hawaiian Islands probability of excess rainfall conditions under current (2002-2012) and future (2090-2099) scenarios

One of the determinants of runoff is the occurrence of excess rainfall events where rainfall rates exceed the infiltration capacity of soils. To help understand runoff risks, we calculated the probability of excess rainfall events across the Hawaiian landscape by comparing the probability distributions of projected rainfall frequency and land cover-specific infiltration capacity. We characterized soil infiltration capacity based on different land cover types (bare soil, grasses, and woody vegetation) and compared them to the frequency of large rainfall events under current and future (pseudo-global warming) climate scenarios. Here we provide a raster stack that contain the probability of excess rainfall exceeding infiltration capacity in each grid cell at 90 m in two bands for current (2002-2012) and future (2090-2099) scenarios.

Compilation of the salient characteristics of numerical groundwater-flow and solute- and heat-transport models published or developed by the U.S. Geological Survey for regions in the U.S. and its territories and commonwealths, 1970 through 2022 (ver. 2.0, March 2025)

The U.S. Geological Survey (USGS) National Extent Hydrogeologic Framework for National Water Census (NEHF) project is a multi-year effort (2022 through 2025) that will compile existing assets (approaches, data, software, etc.), develop a strategic plan, and implement an operational framework that is dynamic and multi-scale. Within the USGS, numerical groundwater-flow and solute- and heat-transport models have been created for a variety of purposes that include water-resource assessments, contaminant-transport evaluations, and water-management planning. These models are often supported by hydrogeologic-framework studies that describe the surface and subsurface distribution of geologic materials and their hydrologic properties. This digital data release was developed as part of the NEHF project to compile, in tabular and spatial form, information on the salient characteristics of numerical groundwater-flow and solute- and heat-transport models published or developed by the USGS for regions in the U.S. and its territories and commonwealths from the date of the earliest published model, 1970, through 2022. Version 2.0 of this data release adds spatial information on the structural and hydrologic properties of a subset of the models.

Grayscale Seismic-Reflection Images in PNG Format from Western Rhode Island Sound (1980)

During 1980, a Uniboom seismic-reflection survey was conducted by the U.S. Geological Survey (USGS) in western Rhode Island Sound aboard the Research Vessel NeechoThe cruise consisted of 2 legs and had a total of 8 survey days. Data from this survey were recorded in analog form and archived at the USGS. As a result of recent interest in the geology of Rhode Island Sound and in an effort to make the data more readily accessible while preserving the original paper records, the seismic data from this cruise were scanned and converted to TIFF and PNG images and SEG-Y data files. In order to scan the lines, some of the paper records were cut and scanned in sections. These sections are labeled with lower-case letters and differ from the names of lines in the logbook. Some SEG-Y files were further divided in order for each file to contain continuous data collected at the same ship speed; these line segments have been labeled _1, _2, or _3 after the section label. Navigation data were converted from LORAN-C time delays to latitudes and longitudes that are available in ESRI shapefile format and as eastings and northings in space-delimited text format.

Trackline navigation for EG&amp;G Uniboom seismic-reflection data collected by the U.S. Geological Survey during field activities 1974-004-FA and 1975-003-FA offshore of the Delmarva Peninsula (polyline shapefiles)

Geologic structure and isopach maps were constructed by interpreting over 19,890 trackline kilometers of co-located multichannel boomer, sparker and chirp seismic reflection profiles from the continental shelf of the Delmarva Peninsula, Maryland and Virginia. In this region, Brothers and others (2020) interpret 12 seismic units and 11 regional unconformities. They interpret the infilled channels as Late Tertiary and Quaternary courses of the Susquehanna, Potomac, Rappahannock, York and James Rivers and tributaries, in addition to a broad drainage system. These regional unconformities form a composite unconformity interpreted as the Quaternary-Tertiary (Q-T) unconformity. A depth to Tertiary (Uqt) and total Quaternary sediment thickness (Q) isopach are included with this data release. Other products in this data release include thickness of an early Pleistocene unit (Qbd), thickness of a Pleistocene highstand system tract (Q2), thickness of a post last glacial maximum (LGM) fluvial/estuarine unit (Qcch), thickness of Holocene to modern marine sediment (Qmn), depth to the base of the Persimmons Point and Ocean City paleochannels (U4), depth to the base of the Exmore and Belle Haven paleochannels (U6), depth to the base of the Eastville paleochannel and tributaries (U8), depth to the base (fluvial unconformity) of the Cape Charles paleochannel and tributary paleochannels (fluvial unconformity, U10) and the base (tidal ravinement) of associated Holocene tidal and back-barrier deposits (tidal ravinement surface, U10.5).

Assessing connectivity among coastal and interior Cactus Wrens in California using population genomics (2021)

The Coastal Cactus Wren is a species of high conservation concern in southern California. The goal of this project was to obtain taxonomic resolution of subspecies boundaries between coastal and desert populations of Cactus Wrens. We collected genetic samples from Cactus Wrens at California desert sites and combined this dataset with previously collected samples from coastal populations to resolve the distribution of subspecies and to determine distinct genetic lineages, gene flow, genetic diversity and effective population size of desert populations. Understanding these relationships will assist managers with development and implementation of a conservation and management strategy that could aim to avoid state or federal listing of this declining species.

Visual description sheets 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.
