Coastwide Reference Monitoring System (CRMS) 2021 Site 0416 land-water classification data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 398 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2021 Color Infrared (CIR) Digital Imagery. These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors. The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition. Five previous assessments have been conducted (2005, 2008, 2012, 2015/2016, and 2018). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Faults--Offshore of Gaviota Map Area, California

This part of DS 781 presents fault data for the geologic and geomorphic map of the Offshore of Gaviota map area, California. The vector data file is included in "Faults_OffshoreGaviota.zip," which is accessible from https://doi.org/10.5066/F7TH8JWJ. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Hartwell, S.R., Golden, N.E., Kvitek, R.G., and Davenport, C.W. (S.Y. Johnson and S.A.

The southwest-striking south strand of the Santa Ynez fault obliquely cuts the shelf in the western part of the map area. As mapped onshore by Dibblee (1950, 1988a) this fault is unique among Santa Barbara fold belt structures in that it obliquely crosses the Santa Ynez Mountains and the dominant east-west structural grain. The fault was difficult to map in the offshore, even with our dense seismic-reflection data coverage, because the pre-LGM section on the shelf includes massive "reflection free" zones, probably associated with gas or steep dips, and the adjacent slope is mainly underlain by massive to chaotic seismic facies of the Conception Fan.

LANDFIRE 2022 Fuel Disturbance (FDist) HI

LANDFIRE (LF) disturbance products are developed to provide temporal and spatial information related to landscape change. LF 2022 Fuel Disturbance (FDist) uses the latest Annual Disturbance products from the effective disturbance years of 2013 to 2022. FDist is created from LF 2022 Historical Disturbance (HDist) which in turn aggregates the Annual Disturbance products. FDist groups similar disturbance types, severities and time since disturbance categories which represent disturbance scenarios within the fuel environment. FDist is used in conjunction with Fuel Vegetation Type (FVT), Cover (FVC), and Height (FVH) to calculate Canopy Cover (CC), Canopy Height (CH), Canopy Bulk Density (CBD), Canopy Base Height (CBH), Fire Behavior Fuel Models 13 Anderson (FBFM13) and 40 Scott and Burgan (FBFM40). 
FDist is developed using the aggregated Annual Disturbance products from 2013 to 2022. All existing disturbances between 2013-2022 are represented in the LF 2022 update, and the products are intended to be used in 2023 (the year of release). The "capable" year terminology used in LF 2020 and LF 2016 Remap is no longer specified, due to reduction in latency from when a disturbance occurs to the release date of fuel products accounting for that disturbance. However, users should still consider adjusting fuel layers for disturbances that occurred after the end of the 2022 fiscal year (after October 1st, 2022) when using the LF 2022 fuel products. Because those changes would not be accounted for. Learn more about LF 2022 at https://landfire.gov/lf_230.php .

0.2-second spectral response acceleration (5% of critical damping) with a 1% probability of exceedance in 1 year

A one-year seismic hazard forecast for the Central and Eastern United States, based on induced and natural  earthquakes, has been produced by the U.S. Geological Survey.  The model assumes that earthquake rates calculated from several different time windows will remain relatively stationary and can be used to forecast earthquake hazard and damage intensity for the year 2017. This assessment is the first step in developing an operational earthquake forecast for the CEUS, and the analysis could be revised with updated seismicity and model parameters. Consensus input models consider alternative earthquake catalog durations, smoothing parameters, maximum magnitudes, and ground motion estimates, and represent uncertainties in earthquake occurrence and diversity of opinion in the science community.  Near some areas of active induced earthquakes, hazard is higher than in the 2014 USGS National Seismic Hazard Model (NSHM) by more than a factor of 3; the 2014 NSHM did not consider induced earthquakes. In some areas, previously observed induced earthquakes have stopped, so the seismic hazard reverts back to the 2014 NSHM.
This data set represents the results of calculations of hazard curves for a grid of points with a spacing of 0.05 degrees in latitude and longitude.  This particular data set is for horizontal spectral response acceleration for 0.2-second period with a 1 percent probability of exceedance in 1 year.  The data are for the Western United States and are based on the long-term 2014 National Seismic Hazard Model.

Old vs. new urban: U.S. national mapping of the year of “first development” for urban areas, from 1940-2010.

This product is a 100-meter resolution raster which classifies urban lands in the conterminous United States by the year in which they were “first developed.”  The classification is based on housing density by era for 1940-2010 developed by the University of Wisconsin-Madison SILVIS lab.  The classification was applied by identifying a housing unit density threshold which matched current-era “development” as represented by U.S. Census Urban Areas polygons, then re-applying that threshold to former eras back to 1940.  The result is a national raster (.tif format) with eight classes, for the years 1940 and before, 1950, 1960, 1970, 1980, 1990, 2000, and 2010, representing the year in which a pixel crossed the threshold of being “developed.”  It is suitable for watershed mean calculations in distinguishing areas which have newly developed areas vs. older developed areas.

Mud logs from the Oxnard Oil Field, Ventura County, California

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (SWRCB) compiled and digitized mud logs from oil and gas wells in the Oxnard Oil Field area. Scanned copies of the mud logs were downloaded from the California Geologic Energy Management Division (CalGEM) online data and were digitized. Thirteen available mud logs associated with the Pliocene Tar Sand pool code (Vaca Tar Sand) were digitized. Mud-logging technology (mud logs) allows for identification and relative concentration measurement in parts per million by volume (ppmv) of light hydrocarbon gases (methane through pentane) occurring in drilling mud returned to the surface throughout the drilling process as well as estimates of percent oil in mud log cuttings (oil shows). The data provided here are apparent concentrations of hydrocarbon gas (methane, ethane, propane, butane, and pentane) and percent oil shows with depth. Apparent concentrations do not equal actual concentrations or presence of the compound at a given depth. Apparent concentrations reflect a digitized position on a mud log and positive values may not indicate presence of the compound; these values are reported as “mud log RAW.csv” values in this data release (see process step 1 and 2 for further description). Estimates of apparent concentration compared to other depths should be estimated by calculating the deviation with depth from the baseline or minimum value. In the larger work, the reported apparent concentrations  represent a relative apparent concentration calculated from the raw digitized data for each mud log and each respective gas component (methane, ethane, propane, butane, and pentane); these value are reported as “mud log PROCESSED.csv” (see process step 3 for further description). A baseline concentration was estimated for each processed mud log and represents the minimum apparent relative gas concentration considered for evaluating the presence of the gas components (see process step 4 for further details). Values above baseline or minimum at a single discrete depth should be regarded with caution. Apparent concentration values should not be compared between sites, as minimum or baseline values result from differences in the digitizing process between sites. These data were analyzed in an accompanying manuscript as part of the SWRCB oil and gas Regional Monitoring Program and the USGS California Oil, Gas, and Groundwater (COGG) program to assess regional groundwater quality overlying and adjacent to the Oxnard Oil Field.

Average-annual streamflow, runoff and baseflow, estimated for the period of record using six hydrograph-separation methods, for 312 gaged basins in the Northwestern Volcanic Aquifer Study Area, USA, 1904-2015.

The U.S. Geological Survey’s Water Availability and Use Study Program (WAUSP) (https://water.usgs.gov/ogw/gwrp/activities/regional.html) supports quantitative assessments of groundwater availability in areas of critical importance. As part of a WAUSP study in the arid to semi-arid Northwest Volcanic Aquifer Study Area (NVASA), estimates of runoff and baseflow were determined for 312 streamflow-gaging stations from 1904 to 2015. Gages with complete water years (October to September) of continuous-streamflow record were used to partition streamflow into runoff and baseflow, which is that part of streamflow attributed to groundwater discharge. For each water year annual estimates of baseflow, runoff, and a base-flow index were determined using a series of automated hydrograph separation programs—PART, HYSEP, and BFI. These streamflow-hydrograph analysis methods are available in the U.S. Geological Survey Groundwater Toolbox (https://water.usgs.gov/ogw/gwtoolbox/), which is a graphical, mapping and analysis interface built within an open-source MapWindow geography information system in a Windows computing environment.

Database for the geologic map of Lassen Volcanic National Park and vicinity, California - Geodatabase

A database of geologic map of Lassen Volcanic National Park as described in the original abstract:
The geologic map of Lassen Volcanic National Park (LVNP) and vicinity encompasses 1,905 square kilometers at the south end of the Cascade Range in Shasta, Lassen, Tehama, and Plumas Counties, northeastern California.  Most of the map area is underlain by middle to late Pleistocene volcanic rocks; Holocene, early Pleistocene, and late Pliocene volcanic rocks (less than 3.5 m.y.) are less common. The southernmost Cascade Range consists of a regional platform of basalt and basaltic andesite, with subordinate andesite and sparse dacite, erupted from small, relatively short-lived volcanoes.  Nested within these regional volcanoes are "volcanic centers," defined as large, long-lived, composite, calc-alkaline edifices erupting the full range of compositions from basalt to rhyolite, but dominated by andesite and dacite.  Volcanic centers are produced by the focusing of basaltic flux from the mantle and resultant enhanced interaction of mafic magma with the crust.  Collectively, volcanic centers mark the axis of the southernmost Cascade Range.  The map area includes the entire, presently active, Lassen Volcanic Center, parts of three older volcanic centers (Maidu, Dittmar, and Latour), and the products of regional volcanism.  The deposits of several glacial advances are widespread.

Zinc concentration data from mayfly exposure experiment

This release is for data on Zinc concentrations and isotopic signatures of an aquatic insect (mayfly, Baetis tricaudatus).  Mayflies were exposed to an aqueous zinc concentration gradient in a laboratory experiment.  Zinc concentrations were measured in water, algae (mayfly food), and different mayfly lifestages.  Natural abundances of carbon and nitrogen isotopes were also measured in different life stages. This data set includes on Zinc data. Isotope data are provided in a separate file. 
The abstract for a journal article explaining the results of the experiment follows below:
Insect metamorphosis often results in substantial chemical changes that can fractionate isotopes and alter contaminant concentrations. We exposed larval mayflies (Baetis tricaudatus) to an aqueous zinc gradient (3-340 µg Zn/l) and measured the change in zinc tissue concentrations at different stages of metamorphosis. We also measured changes in stable isotopes (δ15N and δ13C) in unexposed B. tricaudatus. Zinc concentrations in larvae were positively related to aqueous zinc, increasing 9-fold across the exposure gradient. Zinc concentrations in adults were also positively related to aqueous concentrations, but were 7-fold lower than larvae. However, this relationship varied according to adult substage (subimago vs imago) and sex. Tissue concentrations in female imagoes were not related to exposure concentrations, but the converse was true for all other stage by sex combinations. Metamorphosis also altered isotopic ratios, increasing δ15N, but not δ13C. Thus, the main effects of metamorphosis on insect chemistry were large declines in zinc concentrations coupled with enriched δ15N signatures. For zinc, this change is largely consistent across the aqueous exposure gradient. However, the differences among sexes and stages suggest that caution is warranted when using isotopes or metal concentrations measured in one insect stage (e.g., larvae) to assess risk to wildlife that feed on subsequent life stages (e.g., adults).

Ground conductivity measurements at selected National Wildlife Refuges: Beaver Lake, North Dakota, 2018

Shallow subsurface electrical conductivity was mapped at Beaver Lake National Wildlife Refuge (NWR) in northwest North Dakota using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2018. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 127 line-kilometers (km) of data were acquired over an area of approximately 8 square-kilometers. At this survey location, the 4m transmitter-receiver horizontal co-planar and perpendicular coil orientations did not function due to equipment malfunction. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey path; data were not decoupled from infrastructure noise sources (powerlines, pipelines, fences, etc.) or corrected for sensor pitch or roll. This data release contains raw and processed electromagnetic data. Digital data are described by the data dictionaries. Additional details regarding the processing steps are described in the metadata.
