Digital Shoreline Analysis System version 4.2 Transects with Long-Term Linear Regression Rate Calculations for Washington (WA_transects_LT.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

National Land Cover Database 2001 (NLCD01) Imperviousness Layer Tile 3, Southwest United States: IMPV01_3

This 30-meter resolution data set represents the imperviousness layer for the conterminous 
United States for the 2001 time period. The data have been arranged into four tiles to facilitate 
timely display and manipulation within a Geographic Information System, browse graphic: 
nlcd01-partition. The National Land Cover Data Set for 2001 was produced through a 
cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. 
The MRLC Consortium is a partnership of Federal agencies (www.mrlc.gov), consisting of the 
U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), 
the U.S. Environmental Protection Agency (USEPA), the U.S. Department of Agriculture (USDA), 
the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service 
(USFWS), the Bureau of Land Management (BLM), and the USDA Natural Resources Conservation 
Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, 
and accurate National Land Cover Database (NLCD) circa 2001 for the United States at medium 
spatial resolution. For a detailed definition and discussion on MRLC and the NLCD 2001 products, 
refer to Homer and others (2004) and http://www.mrlc.gov/mrlc2k.asp.. The NLCD 2001 was created 
by partitioning the United States into mapping-zones. A total of 68 mapping-zones browse graphic: 
nlcd01-mappingzones.jpg were delineated within the conterminous United States based on ecoregion 
and geographical characteristics, edge-matching features, and the size requirement of Landsat mosaics. 
Mapping-zones encompass the whole or parts of several states. Questions about the NLCD mapping 
zones can be directed to the NLCD 2001 Land Cover Mapping Team at the USGS/EROS, Sioux Falls, 
SD (605) 594-6151 or mrlc@usgs.gov.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2015, 2018, and 2021 Site 0600 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. 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 390 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. This dataset consists of a matrix of six land-water products (2005, 2008, 2012, 2015, 2018, and 2021).  The resulting matrix has 64 possible classes defined by the combination of land and water categories on those six dates.

Arizona Elk South of Interstate 40 Corridors

South of Interstate 40 elk reside primarily in Arizona’s Game Management Unit (GMU) 8. Upon completing population surveys in 2021, approximately 4,000 elk were estimated to inhabit GMU 8. Their summer range is primarily characterized by high-elevation ponderosa pine forests and grasslands. The elk radiate out from various origin points within their summer range to their winter range, comprised of rims of canyons in the area, including Sycamore Canyon, Tule Canyon, and Government Canyon. This series of canyons creates an impermeable southern boundary for this herd. Their winter range along the rim country is primarily characterized by pinyon-juniper, manzanita, and scrub oak.
Interstate 40 is the primary threat to this herd’s migration corridor, limiting habitat connectivity and highway permeability between the South and North of Interstate 40 elk herds. Successful elk crossings of Interstate 40 are rare, and more than 65 elk-vehicle collisions occur along this stretch per year. To help mitigate this issue, an overpass is currently in the design phase, which will connect these two herds across Interstate 40.
These mapping layers show the location of the migration corridors for elk (Cervus canadensis) in the South of Interstate 40 population in Arizona. They were developed from 71 migration sequences collected from a sample size of 25 animals comprising GPS locations collected every 2 hours.

Mean tidal range of marsh units in Connecticut salt marshes

This data release contains coastal wetland synthesis products for the state of Connecticut. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, wave power, and exposure potential to environmental health stressors are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing federal, state, and local managers with tools to estimate the vulnerability and ecosystem service potential of these wetlands. For this purpose, the response and resilience of coastal wetlands to physical factors need to be assessed in terms of the ensuing change to their vulnerability and ecosystem services. This project has been funded in part by the United States Environmental Protection Agency under assistance agreement DW-014-92531201-1 to N. Ganju.

Magnetotelluric and TEM Data from the Umatilla Indian Reservation Geothermal Resources  Assessment: Phase 2, 2020: Station um201

This data set consists of 19 wideband magnetotelluric (MT) and 23 transient electromagnetic (TEM) soundings collected by the U.S. Geological Survey in June 2020 as part of the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2 project. Each MT station had 4 components, 2 orthogonal magnetic induction coils and 2 horizontal orthogonal electric dipoles.  Data were collected for an average of 18 hours on a repeating schedule of alternating sampling rates of 256 samples/second for 5 hours and 50 minutes and 4096 samples/second for 10 minutes.  The schedules were set such that each station was recording the same schedule to allow for remote reference processing.  Data were processed with a bounded-influence robust remote reference processing scheme (BIRRP v5.2.1, Chave and Thomson, 2004).  Data quality were generally poor due to episodic spikes in the electromagnetic fields likely caused by the power grid.  TEM data were collected in 100 x 100 m loops or 40 x 40 m loops along 4 profiles in areas of interest for geothermal potential.  Files included in this publication include measured electric- and magnetic-field time series for MT data, and TEM soundings and 1-D resistivity models.

Elepaio nest monitoring data in Hawaii Volcanoes National Park from 2015-2017

We evaluated the nesting response of Hawai‘i ‘Elepaio (Chasiempis sandwichensis; Monarchidae), a generalist insectivore, to the removal of black rats using rodenticide in a before-after-control-impact study in high and low, mesic montane habitat recovering from long-term damage from introduced ungulates and weeds. We monitored nesting activity during 2015–2016 before applying diphacinone bait in 2017 to remove rats from two 700 x 700-m treatment plots that were paired with two non-treatment plots. We continued monitoring through July 2017. 
This data set includes a summarized account of Elepaio nests during the 2015, 2016, and 2017 breeding seasons. There is a unique identifier for each nest ('NestID '), along with information on the site, fate (0=fledged, 1=failed), elevation and whether the nest was on a site  treated for black rat removal ('impact'), or a non-treated ('control') plot. Also listed for each entry is the day of the year the nest was found, 'DayFound'; the day it was last known to be active, 'DayLastPresent'; the day it was last checked, 'DayLastChecked', and the age of the nest when found, 'AgeFound'.

Water Chemistry and Smallmouth Bass Biological Data From the Potomac River, Dargan, Maryland, 2013-2019

Decades of poor reproductive success and young-of-the-year recruitment, in addition to adult mortality, has led to a decline in the smallmouth bass (SMB) population in subwatersheds of the Potomac River.  Previous studies have identified numerous biologic and environmental stressors associated with negative effects on SMB health.  To better understand the impact of these stressors, the current study was conducted from 2013-2019 to identify temporal changes associated with SMB reproductive health. Grab surface water samples were collected and analyzed for over 300 organic contaminants, including pesticides, phytoestrogens, pharmaceuticals, hormones and total estrogenicity (E2Eq).  Adult SMB were collected and sampled for multiple endpoints, including gene transcripts associated with reproduction (molecular), histopathology (cellular), and organosomatic indices (tissue).  In males, biomarkers of estrogenic endocrine disruption, including testicular oocytes (TO) and plasma vitellogenin (Vtg) were assessed.  The results identified numerous agriculture-related contaminants or land use associated with gene transcripts in males and females and a positive association of pesticides in the immediate catchment with TO severity and E2Eq with plasma Vtg in males.  Prevalence of TO and detectable levels of plasma Vtg, liver vitellogenin transcripts (vtg) and testis vtg were high throughout the study. Peaks of complex mixtures of numerous contaminants occurred during the spring/early summer when early development occurs and to a lesser extent in fall/winter during recrudescence. Management practices to reduce exposure during these critical and sensitive periods may enhance reproductive health of economically important sportfishes.

Geomorphic Map Malakoff Diggins State Historic Park, California

One of the largest hydraulic mines (1.6 km2) is located in California’s Sierra Nevada within the Humbug Creek watershed and Malakoff Diggins State Historic Park (MDSHP). MDSHP’s denuded and dissected landscape is composed of weathered Eocene auriferous sediments susceptible to chronic rill and gully erosion whereas block failures and debris flows occur in more cohesive terrain. This data release includes a 2014 digital elevation model (DEM), a study area boundary, and a geomorphic map. The 2014 DEM was derived from an available aerial LiDAR dataset collected in 2014 by the California Department of Conservation. The geomorphic map was derived for the study area from using a multi-scale spatial analysis. A topographic position index (TPI) was created using focal statistics to compare the elevations across the study area. We calculated a fine-scale TPI using a circular neighborhood with a radius of 25-meters and large-scale TPI using a circular neighborhood with a radius of 100-meters. In the resulting raster positive TPI values are assigned to cells with elevations higher than the surrounding area and negative TPI values are assigned to cells with elevations lower than the surrounding area. The geomorphic map was then created using a nested conditional statement to apply classification thresholds on the basis the fine and large-scale TPI rasters and a slope raster. Ten geomorphic feature classes were defined and the map can be symbolized by feature class. The geomorphic map includes both channel and hillslope features and can be used to assess erosional and depositional processes at the landscape scale.

Identifying Kittlitz’s Murrelet nesting habitat in North America at the landscape scale

The Kittlitz’s Murrelet (Brachyramphus brevirostris) is a small, non-colonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz’s Murrelet nesting habitat in a few discrete areas, the location and extent of other possible nesting areas throughout most of its range remains unclear. This data release consists of (1) nest locations for the Kittlitz’s Murrelet (2) potential Kittlitz’s Murrelet nesting habitat.

LANDFIRE 2022 Historical Disturbance (HDist) AK

LANDFIRE (LF) disturbance products are developed to provide temporal and spatial information related to landscape change. Historical Disturbance (HDist) is developed from the base annual LF disturbance products, and attribute code system, to represent the history of disturbance for a 10-year span. Each year's disturbance scenarios are checked against time relevant LF vegetation products to check for logical inconsistencies. Errant codes are flagged and updated to a discard code with the remaining disturbance types cross-walked/aggregated to Fuel Disturbance (FDist) types. HDist includes the year of disturbance that is recorded for that pixel. In LF 2022, the time since disturbance code is the same for both HDist and FDist. Starting with LF 2016 Remap, HDist replaced Vegetation Disturbance (VDist) from previous LF versions.
