Depth to 50 percent probability of oxic conditions, Chesapeake Bay Watershed

This dataset is a 900 meter resolution raster representing the depth in meters at which the probability of oxic groundwater occurring is at least 50%, for the Chesapeake Bay watershed. Oxic groundwater was defined as containing O2 values &gt;= 2 mg/L. The values range from 0-100 meters, with 100 representing all depths greater than 100. It was created in support of models which define the oxic/suboxic interface, which is important for determining pathways for nitrate transport in groundwater and in streams.  The dataset was derived from a logistic regression of variables representing surficial geology, position in the flow system, and soil drainage.

Projected future habitat of coastal wetlands in the Nisqually River Delta, Washington

This dataset consists of raster geotiff outputs from modeling vertical accretion and carbon accumulation in the Nisqually River Delta, Washington, USA. These rasters represent projections of future habitat type, change in surface elevation above Mean Sea Level, and total sediment carbon accumulation since 2011 in coastal wetland habitats. Projections were generated in 20-year increments for 100 years for five amounts of sea-level rise, three amounts of suspended sediment concentrations, and two alternative configurations of the U.S. Interstate-5 causeway as it crosses the Nisqually River to either prevent or allow inland habitat migration (a total of 30 scenarios). The full methods and results are described in detail in the parent manuscript, “Can coastal habitats rise to the challenge? Resilience of estuarine habitats, carbon accumulation, and its value to sea-level rise for adaptation planning in a Puget Sound estuary” (2022).

Digital elevation model of Walker Lake, West-Central Nevada

Walker Lake lies within a topographically closed basin in west-central Nevada and is the terminus 
of the Walker River.  Accurately determining the bathymetry and relations between lake-surface 
altitude, surface area, and storage volume are part of a study to improve the water budget for Walker 
Lake.  Bathymetry of Walker Lake was measured using a single-beam echosounder coupled to a 
differentially-corrected global positioning system. Lake depth was subtracted from the lake-surface 
altitude to calculate the altitude of the lake bottom. A Lidar (light detection and ranging) survey and 
high resolution aerial imagery were used to create digital elevation models (DEM) around Walker 
Lake. All data was aquired during 2005.  The altitude of the lake bottom and DEMs were merged 
together to create a single DEM and was used to identify areas that are currently or that were 
submerged by Walker Lake.  The data sets and the procedures used to create the DEM are 
described in this metadata.

Mark-recapture and environmental data used to predict flannelmouth sucker (Catostomous latippinis) growth rates within the Colorado River in the Grand Canyon from April 2012 to October 2018

These data were compiled to fit Bayesian state-space growth in length models to estimate the environmental variables that influence flannelmouth sucker growth rates in the Grand Canyon. Objective(s) of our study were to quantify monthly intervals of growth of flannelmouth suckers in four river reaches, and test if novel high frequency gross primary productivity data would be a significant predictor of fish growth. These data represent capture histories for flannelmouth sucker (Catostomus latippinis) in the mainstem of the Colorado River within the Grand Canyon (river mile 0 to 226) from 2012-2018 and environmental variable data including water temperature, turbidity, and gross primary productivity. Fish data refer to fish length (&gt;150mm fork length), month of capture and spatial location for captures of flannelmouth sucker. These data were collected in the segment of the Colorado River that is within the Grand Canyon, Arizona, between April 2012 to October 2018. Mean monthly water temperature and turbidity data were collected at USGS stream gages at four locations on the Colorado River, and mean monthly gross primary productivity data was collected daily via four Yellow Springs Instrument (YSI) sonds at the same four locations as the stream gages. These data were collected by US Geological Survey, US Fish &amp; Wildlife Service, National Parks Service and Arizona Department of Game and Fish, with funding from the Bureau of Reclamation. Fish data were collected using boat electrofishing and hoop nets, and environmental data was obtained from USGS stream gages. These data can be used to look at spatial and temporal variations in flannelmouth sucker growth.

Transient electromagnetic (TEM) sounding data; San Luis Valley, Colorado, 2009

Transient electromagnetic (TEM) soundings were made in the San Luis Valley, Colorado, to map the location of a blue clay unit as well as to investigate the presence of suspected faults. A total of 147 soundings were made near and in Great Sand Dunes National Park and Preserve, an additional 6 soundings were made near Hansen Bluff on the eastern edge of the Alamosa National Wildlife Refuge. The blue clay is a significant hydrologic feature in the area that separates an unconfined surface aquifer from a deeper confined aquifer. Knowledge of its location is important to regional hydrological models. Previous analysis of well logs has shown that the blue clay has a resistivity of 10 ohm-meters or less, which is in contrast to the higher resistivity of sand, gravel, and other clay units found in the area, making it a very good target for TEM soundings. The top of the blue clay was found to have considerable relief suggesting the possibility of deformation of the clay during or after deposition. Because of rift activity deformation is to be expected. Of the TEM profiles made across faults identified by aeromagnetic data, some showed resistivity variations and (or) subsurface elevation relief of resistivity units suggestive of faulting. Such patterns were not associated with all suspected faults. The Hansen Bluff profile showed variations in resistivity and depth to conductor that coincide with a scarp between the highlands to the east and the floodplain of the Rio Grande River to the west.

Census summary of southern sea otter 2016

The GIS shapefile "Census summary of southern sea otter 2016" provides a standardized tool for examining spatial patterns in abundance and demographic trends of the southern sea otter (Enhydra lutris nereis), based on data collected during the spring 2016 range-wide census. The USGS range-wide sea otter census has been undertaken twice a year since 1982, once in May and once in October, using consistent methodology involving both ground-based and aerial-based counts. The spring census is considered more accurate than the fall count, and provides the primary basis for gauging population trends by State and Federal management agencies. This Shape file includes a series of summary statistics derived from the raw census data, including sea otter density (otters per square km of habitat), linear density (otters per km of coastline), relative pup abundance (ratio of pups to independent animals) and 5-year population trend (calculated as exponential rate of change). All statistics are calculated and plotted for small sections of habitat in order to illustrate local variation in these statistics across the entire mainland distribution of sea otters in California (as of 2016). Sea otter habitat is considered to extend offshore from the mean low tide line and out to the 60m isobath: this depth range includes over 99% of sea otter feeding dives, based on dive-depth data from radio tagged sea otters (Tinker et al 2006, 2007). Sea otter distribution in California (the mainland range) is considered to comprise this band of potential habitat stretching along the coast of California, and bounded to the north and south by range limits defined as "the points farthest from the range center at which 5 or more otters are counted within a 10km contiguous stretch of coastline (as measured along the 10m bathymetric contour) during the two most recent spring censuses, or at which these same criteria were met in the previous year". The polygon corresponding to the range definition was then sub-divided into onshore/offshore strips roughly 500 meters in width. The boundaries between these strips correspond to ATOS (As-The-Otter-Swims) points, which are arbitrary locations established approximately every 500 meters along a smoothed 5 fathom bathymetric contour (line) offshore of the State of California.

Station and data summary for data collected on Stellwagen Bank during U.S. Geological Survey field activity 2013-044-FA, aboard the R/V Auk, November 5, 15, and 21, 2013

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 81 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2015, 2018, and 2021 Site 0660 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.

Development of a Multimetric Index (MMI) for Integrated Assessment of Salt Marsh Ecosystem Condition_NCBN Vegetation &amp; Nekton Data

This dataset is comprised of eight files related to salt marsh monitoring data or measures of of human disturbance (i.e. human impacts in terms of physical, chemical, and land-use stressors) collected at 33 marsh study units (MSUs) in five National Parks within the NPS Northeast Coastal and Barrier Network (NCBN) along the northeastern coast of the US. Two files contain data related to the species and coverage of salt marsh vegetation observed in MSUs (1 data file, 1 definitions file). Two files contain data related to the species and abundance of nekton collected from creeks, pools and ditches in MSUs (1 data file, 1 definitions file). Two files contain data related to the height of key salt marsh vegetation species observed in MSUs (1 data file, 1 definitions file).  Two files contain data related to metrics describing the degree of human disturbance in MSUs (1 data file, 1 definitions file).  Salt marsh monitoring data were generally collected from 2008-2013; however, salt marsh monitoring data were collected irregularly between 1997 and 2007 as part of a pilot program in a small number of the MSUs. Human disturbance metrics were derived from existing aerial imagery and the 2006 National Land Cover Database.

LANDFIRE 2016 Remap Existing Vegetation Height (EVH) Micronesia

LANDFIRE's (LF) 2016 Remap (Remap) Existing Vegetation Height (EVH) represents the average height of the dominant vegetation for a 30m cell. EVH is produced separately for tree, shrub, and herbaceous lifeforms using training data depicting the average height weighted by species cover and Existing Vegetation Type (EVT) lifeform. Decision tree models using field reference data, lidar, Landsat, and ancillary data are developed separately for each lifeform, then lifeform specific height class layers are merged along with land cover into a single EVH product. EVH ranges are continuous for herbaceous lifeform ranging from 0.1 to 1 meter with decimeter increments, 0.1 to 3 meters for shrub lifeform, and 1 to 99 meters for tree lifeform. If the height values of each lifeform exceed the continuous value range, they are binned into the appropriate maximum height class. EVH is then reconciled through QA/QC measures to ensure lifeform is synchronized with both Existing Vegetation Cover (EVC) and EVT products. Disturbance events not visible in the source imagery are accounted for by using LF Remap Annual Disturbance products. LF uses EVH as an input for LF Remap Fuel Vegetation Cover (FVH).
