The northern portition of the gather area contains this type of land pattern.

Management Alternatives And Environmental Assessment, Mormon Row Historic District Grand Teton National Park, Wyoming, United States, Department Of The Interior, National Park Service

Environmental Assessments (WY)

Few people visiting Mormon Row today realize that the six remaining homesteads constitute about a fifth of those that once defined the Mormon Row community. Time and the harsh climate have taken an extreme toll. Most structures that remain stand abandoned and in need of repair. The farms are not interpreted and most visitors probably do not even know that the historic area is within the boundaries of Grand Teton National Park. Nevertheless, the area receives a light but steady amount of visitation. Visitors remark about inadequate parking, lack of interpretation, the deteriorated condition of many of the historic structures, …

Lethal Sandslides From Eolian Dunes, David B. Loope, Joseph A. Mason, Lowell Dingus

Department of Earth and Atmospheric Sciences: Faculty Publications

Fossil vertebrates entombed within the Upper Cretaceous Djadokhta Formation of southern Mongolia bear testimony to a heretofore unknown geologic phenomenon: mass wasting of eolian dunes during heavy rainstorms. Evaporation of shallow-penetrating rainwater led to progressive calcite accumulation in a thin layer of sand about 0.5 m below the surface of dune lee slopes. During rare heavy rainstorms, a perched water table developed at the top of calcitic zones. Positive pore water pressure led to translational slides and fast-moving sediment gravity flows that overwhelmed animals on the lee slopes of large dunes and in interdune areas.

Redevelopment Strategies For The Usx/Cement Plant Site In Duluth, Minnesota,, Kirstin Toth, Donald T. Iannone

All Maxine Goodman Levin School of Urban Affairs Publications

In May 1999, the Great Lakes Environmental Finance Center (GLEFC) conducted a strategy-building workshop in Duluth, Minnesota. The purpose of the workshop was to assist the City of Duluth in its efforts to develop actions leading to the successful redevelopment of the USX/Cement Plant site. Particular emphasis was placed on financing strategies pertinent to properties with a history of environmental contamination, often characterized as brownfields. Due to its long history as an industrial site, the 65-acre Cement Plant had its share of perceived environmental contamination, as well as real contaminants detected during previous site assessments and a current Phase I …

Acetate Retention And Metabolism In Thehyporheic Zone Of A Mountain Stream, Michelle A. Baker

Michelle A. Baker

An in situ acetate injection was used to determine the influence of labile dissolved organic carbon (DOC) availability on microbial respiration in the hyporheic zone of a headwater stream. We added bromide as a conservative tracer and acetate as an organic substrate to the hyporheic zone of Rio Calaveras, New Mexico, via an injection well. Tracer was observed in four of eight capture wells. Three of the four wells showed increases in bromide without concurrent increases in acetate concentration, suggesting 100% acetate retention. One well had 38% acetate retention. Pore velocity and acetate retention were negatively correlated, suggesting hydrologic control …

Some Aspects Of The Adsorption Of A Lennard-Jones Gas On A Rough Surface, Douglas Henderson, Pawel Bryk, Stefan Sokolowski

Faculty Publications

We study the adsorption, including wetting, of a Lennard-Jones gas on a rough surface consisting of rough layer on a smooth substrate with which the gas interacts via a 9-3 potential. The rough layer is two molecular diameters thick and consists of a disordered quenched matrix of hard spheres. As well as interacting with the other matrix spheres by the hard-sphere potential, the matrix molecules interact with the gas molecules by the hard-sphere potential. Hence, on average, the degree to which the gas molecules can approach the substrate depends only on the density of the matrix layer. The density of …

Comparison Of Methods For Calculating The Properties Of Intramolecular Hydrogen Bonds. Excited State Proton Transfer, T. Kar, Steve Scheiner, M. Cuma

Steve Scheiner

A series of molecules related to malonaldehyde, containing an intramolecular H-bond, are used as the testbed for a variety of levels of ab initio calculation. Of particular interest are the excitation energies of the first set of valence excited states, nπ^∗ and ππ^∗, both singlet and triplet, as well as the energetics of proton transfer in each state. Taking coupled cluster results as a point of reference, configuration interaction-singles–second-order Møller–Plesset (CIS–MP2) excitation energies are too large, as are CIS to a lesser extent, although these approaches successfully reproduce the order of the various states. The …

The Development And Validation Of A Methodology For The Analysis Of Polyaromatic Hydrocarbons In Air Particulates (Indoor And Outdoor), Kathryn O'Malley

Masters

PAH form a large class of ubiquitous pollutants mainly of anthropogenic origin. Several PAH found in air particulates have been identified as carcinogens and mutagens. Sixteen of these PAH have been listed by the USEPA as priority pollutants. This research is concerned with the development and optimisation of a method for the analysis of these sixteen PAH in air particulates. Soxhlet and ultrasonic extraction procedures were investigated to optimise the recoveries from spiked glass fibre filters with a standard 1ppm mixture of the 16PAH. Standard mixtures of the 16 PAH were analysed by HPLC with fluorescence detection with approx. linearity …

Effect Of The Environmental Parameters On The Distribution Of Foraminifera In The Coastal Area Of Ras Al Khaimah, U.A.E., Naama Obaid Saif Al-Kaabi

Analysis of sea water for the environmental parameters includs, temperature, salinity and nutrient salts (nitrate, nitrite, silicate, phosphate and amonia). Organic mattar, and total carbonate were measured in the bottom sediments. Grain size analysis of the bottom sediments was done using seiving method. The foraminiferal species were picked, counted and photographed using the SEM. The ratio of dead to living forams was …

Frontogenesis In The North Pacific Oceanic Frontal Zones--A Numerical Simulation, Michael S. Dinniman, Michele M. Rienecker

CCPO Publications

A primitive equation model [Geophysical Fluid Dynamics Laboratory's (GFDL's) MOM 2] with one degree horizontal resolution is used to simulate the seasonal cycle of frontogenesis in the subarctic frontal zone (SAFZ) and the subtropical frontal zone (STFZ) of the North Pacific Ocean. The SAFZ in the model contains deep (greater than 500 m in some places) regions with seasonally varying high gradients in temperature and salinity. The gradients generally weaken toward the east. The STFZ consists of a relatively shallow (less than 200 m in most places) region of high gradient in temperature that disappears in the summer/fall. The high …

Continental Runoff And Effects On The North Atlantic Ocean Subtropical Mode Water, Larry P. Atkinson, Chester E. Grosch

CCPO Publications

Interannual salinity variations in North Atlantic Subtropical Mode Water (STMW) are well known although the cause is less well understood. Attempts to model local salinity variation with local evaporation and precipitation have not been successful and some authors invoke advection of low salinity water as the cause. Examination of the STMW and North American river runoff data suggests that runoff may partly explain the salinity variations. It is known that low salinity water resulting from Mississippi River outflow is transported well past Cape Hatteras. Spearman Rank Correlation analysis and spectra and cross-spectra Fourier correlation analysis both show that river flow …

Spectroscopy Of Brown Dwarf Candidates In The Ρ Ophiuchi Molecular Core, Bruce Wilking, Thomas Greene, Michael Meyer

Physics Faculty Works

We present an analysis of low-resolution infrared spectra for 20 brown dwarf candidates in the core of the ρ Ophiuchi molecular cloud. Fifteen of the sources display absorption-line spectra characteristic of late-type stars. By comparing the depths of water vapor absorption bands in our candidate objects with a grid of M dwarf standards, we derive spectral types that are independent of reddening. Optical spectroscopy of one brown dwarf candidate confirms the spectral type derived from the water bands. Combining their spectral types with published near-infrared photometry, effective temperatures and bolometric stellar luminosities are derived, enabling us to place our sample …

Modification Of No, Po, And No/Po During Flow Across The Bering And Chukchi Shelves: Implications For Use As Arctic Water Mass Tracers, Lee W. Cooper, Glenn F. Cota, Lawrence R. Pomeroy, Jacqueline M. Grebmeier, Terry E. Whitledge

CCPO Publications

The NO and PO tracers (9[NO₃-] + 02 and 135[PO₄-] + 02, respectively,) and their derivative NO/PO have found increasing use in Arctic water mass analyses for identifying the specific basin or shelf areas from which surface waters originate, based upon assumed differences in Pacific- and Atlantic-derived content and basin-to-basin differences within the Arctic. Following shipboard sampling in June-September 1993 and May-June 1994, both north and south of Bering Strait, we have found evidence that Pacific-derived waters flowing north to Bering Strait do not necessarily have any unique NO, PO, or NO/PO identity that would permit …

Evolution Of The Electronic Structure And Properties Of Neutral And Charged Aluminum Clusters: A Comprehensive Analysis, B. K. Rao, P. Jena

Physics Publications

Density-functional theory with generalized gradient approximation for the exchange-correlation potential has been used to calculate the global equilibrium geometries and electronic structure of neutral, cationic, and anionic aluminumclusters containing up to 15 atoms. The total energies of these clusters are then used to study the evolution of their binding energy, relative stability, fragmentation channels, ionization potential, and vertical and adiabatic electron affinities as a function of size. The geometries are found to undergo a structural change from two dimensional to three dimensional when the cluster contains 6 atoms. An interior atom emerges only when clusters contain 11 or more atoms. …
