An aerial radiological survey of Project Rulison and surrounding area, Battlement Creek Valley, Colorado

Description: An aerial radiological survey was conducted over the Project Rulison site, 40 miles (64 kilometers) northeast of Grand Junction, Colorado, from July 6 through July 12, 1993. Parallel lines were flown at intervals of 250 feet (76 meters) over a 6.5-square-mile (17-square-kilometer) area at a 200-foot (61-meter) altitude surrounding Battlement Creek Valley. The gamma energy spectra obtained were reduced to an exposure rate contour map overlaid on a high altitude aerial photograph of the area. The… more

Aerial Radiation Detection

Description: An airborne system designed for the detection of radioactive sources on the soil surface from an aircraft normally senses gamma rays emitted by the source. Gamma rays have the longest path length (least attenuation) through the air of any of the common radioactive emissions and will thus permit source detection at large distances. A secondary benefit from gamma rays detection if that nearly all radioactive isotopes can be identified by the spectrum of gammas emitted. Major gaseous emissions fro… more

Environmental waste site characterization utilizing aerial photographs, remote sensing, and surface geophysics

Description: Six different techniques were used to delineate 40 year old trench boundary at Los Alamos National Laboratory. Data from historical aerial photographs, a magnetic gradient survey, airborne multispectral and thermal infra-red imagery, seismic refraction, DC resistivity, and total field magnetometry were utilized in this process. Each data set indicated a southern and northern edge for the trench. Average locations and 95% confidence limits for each edge were determined along a survey line perpen… more

Using Historical Aerial Photography and Softcopy Photogrammetry for Waste Unit Mapping in L Lake.

Description: L Lake was developed as a cooling water reservoir for the L Reactor at the Savannah River Site. The construction of the lake, which began in the fall of 1984, altered the structure and function of Steel Creek. Completed in the fall of 1985, L Lake has a capacity of 31 million cubic meters and a normal pool of 58 meters. When L Reactor operations ceased in 1988, the water level in the lake still had to be maintained. Site managers are currently trying to determine the feasibility of draining or … more

Research on the Seasonal Snow of the Arctic Slope. Annual Progress Report, July 15, 1984--January 15, 1986

Description: This project deals with the seasonal snow on Alaska`s Arctic Slope. It is concentrated on snow of the R{sub 4}D project area. However, an important aspect of this study is to relate the snow cover of this area with the rest of the Arctic Slope. The goals include determination of the amount of precipitation which comes as snow, the wind transport of this snow and its depositional pattern as influenced by drifting, the physical properties of the snow, the physical processes which operate in it, t… more

Photogeologic and kinematic analysis of lineaments at Yucca Mountain, Nevada: Implications for strike-slip faulting and oroclinal bending

Description: The main structural grain at Yucca Mountain, as seen from aerial photographs, is a pronounced north-trending linear fabric defined by parallel east-tilted fault-block ridges. The ridges are bounded on the west by normal faults that are easily recognizable on aerial photographs, mainly as isolated, colinear scarps in alluvium and as offset bedrock units. AH ridge-bounding to adjacent faults, most commonly by short northwest-trending fault splays. The generally north-trending high-angle faults pr… more

Airborne detection of magnetic anomalies associated with soils on the Oak Ridge Reservation, Tennessee

Description: Reconnaissance airborne geophysical data acquired over the 35,000-acre Oak Ridge Reservation (ORR), TN, show several magnetic anomalies over undisturbed areas mapped as Copper Ridge Dolomite (CRD). The anomalies of interest are most apparent in magnetic gradient maps where they exceed 0.06 nT/m and in some cases exceed 0.5 nT/m. Anomalies as large as 25nT are seen on maps. Some of the anomalies correlate with known or suspected karst, or with apparent conductivity anomalies calculated from elec… more

Environmental waste site characterization utilizing aerial photographs and satellite imagery: Three sites in New Mexico, USA

Description: The proper handling and characterization of past hazardous waste sites is becoming more and more important as world population extends into areas previously deemed undesirable. Historical photographs, past records, current aerial satellite imagery can play an important role in characterizing these sites. These data provide clear insight into defining problem areas which can be surface samples for further detail. Three such areas are discussed in this paper: (1) nuclear wastes buried in trenches… more

Open Skies: Facilitating the many dimensions of transparency

Description: The Treaty on Open Skies (Open Skies) was signed on 24 March 1992 by 23 European nations in addition to the United States and Canada. Unlike other arms control treaties which prohibit specific weapons or weapon systems, Open Skies is intended to provide, in the words of its preamble, means ``to facilitate the monitoring of compliance with existing or future arms control agreements.`` In addition, its objectives include the ``improvement of openness and transparency for conflict prevention and c… more

Development of Autonomous Magnetometer Rotorcraft For Wide Area Assessment

Description: Large areas across the United States and internationally are potentially contaminated with unexploded ordinance (UXO), with some ranges encompassing tens to hundreds of thousands of acres. Technologies are needed which will allow for cost effective wide area scanning with (1) near 100% coverage and (2) near 100% detection of subsurface ordnance or features indicative of subsurface ordnance. The current approach to wide area assessment is a multi-level one, in which medium - altitude fixed wing … more

Naturally fractured tight gas reservoir detection optimization

Description: Exploration strategies are needed to identify subtle basement features critical to locating fractured regions in advance of drilling in tight gas reservoirs. The Piceance Basin served as a demonstration site for an analysis utilizing aeromagnetic surveys, remote sensing, Landsat Thematic Mapper, and Side Looking Airborne Radar imagery for the basin and surrounding areas. Spatially detailed aeromagnetic maps were used to to interpret zones of basement structure.

Use of aerial videography to evaluate the effects of Flaming Gorge Dam operations on natural resources of the Green River

Description: Peaking hydropower operations can profoundly alter natural stream flow and thereby affect the natural resources dependent on these flows. In this paper, we describe how aerial videography was used to collect environmental data and evaluate impacts of hydropower operations at Flaming Gorge Dam on natural resources of the Green River. An airborne multispectral video/radiometer remote sensing system was used to collect resource data under four different flow conditions from seven sites (each about… more
