Geoecology: a county-level environmental data base for the conterminous United States

Description: The Geoecology Data Base represents a unique compilation of computerized environmental data for research and development needs. Environmental assessment and planning for energy development require rapid access to data at appropriate spatial and temporal scales. In the Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL), we have developed an integrated data base of diverse environmental resource information from extant sources. Data are stored at the county level of res… more

Environmental baseline study of the Los Medanos Waste Isolation Pilot Plant (WIPP) project area of New Mexico: a progress report

Description: Exploratory drilling operations are being conducted for a Waste Isolation Pilot Program in southeastern New Mexico. Prior to the establishment of such a program, an environmental study was initiated to serve as a baseline for evaluation of the impact of future activities in the Los Medanos area. Much of this area has been influenced by human activities over a long period, and hence the baseline data only reflects the present, relatively disturbed condition of the environment. The study covers a… more

Off-nadir optical remote sensing from satellites for vegetation identification

Description: Today's satellite remote sensing systems rely heavily on spectral signatures for scene identification from nadir observations. We propose to use angular signatures as complementary scene identifiers when off-nadir sensing is possible. Specifically, the hot spot (Heiligenschein) of plant canopies is recognized as an atmosphere-invariant angular reflectance signature that carries information about the plant stand architecture which may be useful for instant crop identification from off-nadir sate… more

Canopy hot-spot as crop identifier

Description: Illuminating any reflective rough or structured surface by a directional light source results in an angular reflectance distribution that shows a narrow peak in the direction of retro-reflection. This is called the Heiligenschein or hot-spot of vegetation canopies and is caused by mutual shading of leaves. The angular intensity distribution of the hot-spot, its brightness and slope, are therefore indicators of the plant's geometry. We propose the use of hot-spot characteristics as crop identifi… more

Diets of mule deer within steppe vegetation of south central Washington. [Dietary preferences at three locations on the Hanford Reservation]

Description: The diets of mule deer (Odocoileus hemionus hemionus) on shrub-steppe rangeland of south central Washington were estimated by microhistological examination of fecal pellets. On rangelands, it is necessary to know the diets of herbivores and availability of forage plants to provide information for formulating better management programs for both plants and animals. The purpose of this study was to determine the dietary habits of mule deer at three locations on the 200 area plateau of the Hanford … more

Genetic algorithms and classifier systems: Foundations and future directions

Description: Theoretical questions about classifier systems, with rare exceptions, apply equally to other adaptive nonlinear networks (ANNs) such as the connectionist models of cognitive psychology, the immune system, economic systems, ecologies, and genetic systems. This paper discusses pervasive properties of ANNs and the kinds of mathematics relevant to questions about these properties. It discusses relevant functional extensions of the basic classifier system and extensions of the extant mathematical th… more

Shrub and tree data for plant associations across the Mojave/Great Basin Desert transition of the Nevada Test Site, 1963--1975

Description: The shrub, tree, and cactus vegetation of 59 selected study sites in eight drainage basins of the Nevada Test Site was documented in 1963, and again in 1975. Vegetation of the sites, which span the range of 3076 to 7425 ft elevation, is assigned to five plant associations, and intergrades, on the 25 Mojave Desert sites; eight associations on the 10 Great Basin Desert sites; and six associations, and ecotonal types, on the 24 sites of the desert transition. The data presented are for numbers of … more

Literature review of models for estimating soil erosion and deposition from wind stresses on uranium-mill-tailings covers

Description: Pacific Northwest Laboratory (PNL) is investigating the use of a rock armoring blanket (riprap) to mitigate wind and water erosion of an earthen radon-suppression cover applied to uranium-mill tailings. The mechanics of wind erosion, as well as of soil deposition, are discussed in this report. Several wind erosion models are reviewed to determine if they can be used to estimate the erosion of soil from a mill-tailings cover. One model, developed by W.S. Chepil, contains the most-important facto… more

Use of wetlands for treating wastes: wisdom in diversity. [Kissimmee Valley, Florida wetland management model]

Description: Preliminary analysis of data from two Kissimmee Valley, Florida wetland models operating continuously over the past four years suggest that increased diversity may be one of the major factors in the startling ability of certain wetland systems to retain high amounts of nutrients. According to preliminary analysis of total phosphorus, increasing the number of biotopes, or ecocomponents, in a flow sequence will increase the ability of systems to take up and retain a greater amount of nutrients th… more
