Summary
Description
The San Luis Valley was chosen as a contaminant study site under the U.S. Fish and Wildlife Services Service Region 6 Hot Spot study program in 1987. The Service Hot Spot studies were designed to monitor certain areas for contaminants in fish and wildlife. These Hot Spots are of significant biological importance and were selected with regard to environmental and geological factors that create potential contaminant problems for fish and wildlife. In many cases, previous information has suggested the possibility of a contaminant problem. Geologically speaking, the northern half of the San Luis Valley is a closed basin system that contains and accumulates all of the water that enters the northern portion of the valley. As a result, this closed basin has a valuable ground water supply in the form of both confined and unconfined aquifers U.S. Geological Survey, 1989. A network of irrigation and drainage ditches provides some of this water to other areas of the valley. With a variety of water sources, especially from the surrounding mountains, the valleys water supply could potentially accumulate environmental contaminants as it enters the valley and is stored in this unique hydrologic system. If present, these contaminants could be trapped in the valley, become available to fish and wildlife, and possibly endanger the groundwater supply. Results of this study identify three major stream drainages that are apparently being directly impacted by past and present mining activity in the area. These streams are Willow Creek, Kerber Creek, and Wightman Fork. Biota, water, and sediment samples from these areas and downstream sites contain high concentrations of metals including aluminum, cadmium, copper, lead, mercury, and zinc. In addition, liver samples from great blue herons found dead on Monte Vista National Wildlife Refuge contained high concentrations of mercury and selenium.

Description
Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD); and (3) special designations recognizing waters of exceptional quality as defined in State water quality standards. Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers). Information on State-designated uses and waters of exceptional quality are only available for a limited number of parks at this time.

Description
The Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) has performed a coastal survey along the Atlantic coast of RI in 2010. The data types collected include bathymetry and topographic lidar point data, true color imagery and hyperspectral imagery. The collection effort follows the coastline and extends 500m inland and 1000m offshore or to laser extinction, whichever comes first. Topographic lidar is collected with 200% coverage, yielding a nominal 1m x 1m post-spacing. Where water conditions permit, the bathymetry lidar data will have a nominal post spacing of 4m x 4m. The true color imagery will have a pixel size approximately 35cm and the hyperspectral imagery will be provided in 1m pixels containing 36 bands between 375 - 1050 nm with 19 nm bandwidth. The final data will be tied to horizontal positions, provided in decimal degrees of latitude and longitude, and are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88).

Issued over 9 years ago
Summary
Description
A unique laboratory exposure system was used in applying environmentally relevant conditions river traffic simulations and environmentally relevant sediment concentrations total suspended solids 300 mgL to determine the bioaccumulation and biological response of sediment associated contaminants in fish. We used sediments collected from areas of the upper Mississippi River reported high in metal concentrations and assessed the bioaccumulation of sediment associated arsenic, cadmium, copper, lead, and zinc to green sunfish following 28 days of intermittent pulses of contaminated suspended sediments and sediments not in suspension bedded. Blood enzyme activity deltaaminolevulinic acid dehydratase, ALAD was assessed in the fish as an indicator or biomarker of exposure to lead present in the contaminated suspended and bedded sediments. Results of the metal analysis of filtered and unfiltered water from all treatments indicated that the majority of the metals were associated with particulate matter in suspension. The bioconcentration of copper, lead, and zinc were greater in fish exposed to suspended sediments than bedded sediments as evidence of greater body burden. Arsenic and cadmium concentrations in whole fish were not significantly different in suspended or bedded tests due to low ambient concentrations. The suspended test resulted in greater blood lead 0.02 0.2 ugmL and blood zinc 8.80 14.5 ugmL concentrations than were observed in the bedded tests. And although neither; blood lead nor zinc significantly correlated with ALAD activity, the enzyme was significantly reduced in fish subjected to suspended contaminated sediments compared to fish exposed to bedded contaminated sediments.
Geodatabase of the datasets that represent the three subareas of the Silurian-Devonian aquifer, Illinois, Indiana, Iowa, Kentucky, Michigan, Missouri, Ohio, Tennessee, and Wisconsin

Summary
Description
This geodatabase includes spatial datasets that represent the Silurian-Devonian aquifers in the States of Illinois, Indiana, Iowa, Kentucky, Michigan, Missouri, Ohio, Tennessee, and Wisconsin. Included are: (1) polygon extents; datasets that represent the aquifer system extent, and the entire extent subdivided into subareas, (2) raster datasets for the altitude of the top and bottom surfaces of the entire aquifer (where data are available), and (3) altitude contours used to generate the surface rasters. The digitized contours are supplied for reference. The extent of the Silurian-Devonian aquifers is from the linework of the Silurian-Devonian aquifer extent maps in U.S. Geological Survey U.S. Geological Survey Hydrologic Atlas 730, Chapters J and K, (USGS HA 730-J, -K) and a digital version of the aquifer extent presented in the National Aquifer Code Reference List, available at http://water.usgs.gov/ogw/NatlAqCode-reflist.html , "silurian.zip". The extent was then modified for each subarea: Subarea 1 (sa1): Primarily in Ohio and Indiana, subject of U.S. Geological Survey Professional Paper 1423 B (USGS PP 1423B). Subarea 2 (sa2): In Iowa. Digital data were available from the Iowa Geologic Survey. Subarea 3 (sa3): Remaining area in Illinois, Wisconsin, Michigan, and Kentucky. Extent is that part of the National Aquifer Code Reference List polygon that remained when the areas of sa1 and sa2 were removed. The altitude and thickness contours that were available for each subarea were compiled or generated from georeferenced figures of altitude contours in USGS PP 1423B for sa1, digital data from IAGS for sa2. There were no vertical data for sa3. The resultant top and bottom altitude values were interpolated into surface rasters within a GIS using tools that create hydrologically correct surfaces from contour data, derive the altitude from the thickness (depth from the land surface), and merge the subareas into a single surface. The primary tool was an enhanced version of "Topo to Raster" used in ArcGIS, ArcMap, Esri 2014. The raster surfaces were corrected in the areas where the altitude of an underlying layer of the aquifer exceeded the altitude of an overlying layer.

The enhanced National Land Cover Data 1992 ("NLCDe 92") served as the primary source for nationally consistent mapped land cover during the first decade of sampling for the National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey (USGS). This 30-meter (30-m) resolution digital map was developed by overlaying USGS's original satellite imagery-based 1992 National Land Cover Data ("NLCD 92") with selected classifications from USGS's aerial-photograph-based Land Use and Land Cover (LULC) data of the 1970s to mid-1980s. The LULC data set were combined with NLCD 92 because 1) some land land cover types important to NAWQA were not fully represented in the NLCD 92 and 2) the LULC data set is accepted as a better source of information for certain land cover types that are difficult to interpret from satellite imagery alone. Decision rules were used to modify the NLCD 92 data set based on the co-located LULC data on a cell-by-cell basis. The LULC classifications that were used to develop NLCDe 92 were "Residential," "Orchards, Groves, Vineyards, Nurseries, and Ornamental Horticultural Areas," and all 5 classifications of Tundra. Although NLCDe 92 is nominally referenced to 1992, it generally represents conditions in the early 1990s, the time period when the majority of the imagery for NLCD 92 was captured.

AquaScan: A miniaturized UV/VIS/IR hyperspectral imager for autonomous airborne and underwater imaging spectroscopy of coastal & oceanic environments Project
Published By National Aeronautics and Space Administration
Issued over 9 years ago
Summary
Description
The AquaScan, a miniaturized UV/VIS/NIR hyperspectral imager will be built for deployment on a UAV or small manned aircraft for ocean coastal remote sensing applications. The hyperspectral system includes a data acquisition system with remote operation capability proving a real-time waterfall display of the hyperspectral scans. OKSI teamed with Scripps Institution of Oceanography to define and design a sensor that explicitly meets the performance requirements needed for ocean remote sensing of coastal regions, but can also be used for terrestrial remote sensing. Specifically, some key requirements called for: 1) high spatial resolution (< 1 meter), 2) high spectral resolution (< 10 nm), UV NIR coverage (300 1000 nm), 4) high sensitivity for low reflectivity of ocean surfaces, 5) provide simultaneous downwelling solar radiation measurements, and 6) allow for operating mode that avoids specular reflections off ocean surface. The AquaScan design was completed during the Phase I effort. During Phase II the sensor will be manufactured, tested, calibrated, and prepared for flight testing. The system will then be demonstrated during several airborne tests off the Southern California coast. The tests will include measurements of spatially/spectrally unique ocean phenomena including red tide blooms and river plume run-offs after heavy rain storms. Coordinated ship-based remote sensing and in situ measurements will take place concurrently with the newly developed miniature UV/VIS/NIR airborne measurements. The ship-based measurements will serve as ground truth for validation/verification. In addition, OKSI will attempt to coordinate data collections with satellite passes (e.g., MODIS, MERIS, SeaWiFS). Comparison with satellite data will serve as validation and demonstration of the capability to support future satellite programs (e.g., GEO-CAPE).

A searchable database of all Solar Dynamics Observatory data including EUV, magnetograms, visible light and X-ray. SDO: The Solar Dynamics Observatory is the first mission to be launched for NASA's Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth. SDO is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously. SDO's goal is to understand, driving towards a predictive capability, the solar variations that influence life on Earth and humanity's technological systems by determining how the Sun's magnetic field is generated and structured and how this stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and variations in the solar irradiance.
