Searching For Max: The Engineer, The War And The World´S Longest Cave (Part 1), Bernd Kliebhan Oct 2008

Searching For Max: The Engineer, The War And The World´S Longest Cave (Part 1), Bernd Kliebhan

Mammoth Cave Research Symposia

In 1908 the German engineer Max Kämper mapped 35 miles of Mammoth Cave, KY. The “Kämper Map,” forgotten in the archives for half a century, is nowadays considered as a masterpiece of underground cartography. Little was known about Max Kämper despite several attempts of American speleo-historians. Most traces were wiped out in two world wars. Nevertheless the authors could find out details of the biography of Max Kämper in German archives. The text is based based upon the radio story “Suche nach Max,” broadcasted by Hessischer Rundfunk - hr1 December 26, 1999, audio download available on http://www.kliebhan.de/kaemper.htm

The Lamps That Lit Their Way, Rick Olson Oct 2008

The Lamps That Lit Their Way, Rick Olson

Mammoth Cave Research Symposia

The distinctive lanterns used at Mammoth Cave from the middle 1800s until 1938 appear to be a locally derived design. Early whale oil railroad lanterns share some characteristics of the Mammoth Cave lanterns, but L&N Railroad lanterns do not appear to have influenced the design. At this time, the design pathway appears to lead from simple open-flame tin candle lanterns to the same lantern with a petticoat lamp affixed in place of the candle, and then finally to the font or oil container being soldered onto the lamp base as one unit. This basic Mammoth Cave lantern varied somewhat over …

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker Oct 2008

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker

Mammoth Cave Research Symposia

Maps came first at Mammoth Cave, Kentucky. Then came explorers who used the maps to make discoveries as they gained a more comprehensive understanding of the longest cave in the world. The saga of mapping at Mammoth Cave parallels the mapping of North America from the 1600s onward. The first map was an “Eye-Draught Map of Mammoth Cave”, penned from memory in 1811, not a survey, to acquaint merchants with the location of saltpeter dirt. In 1835 the managers of Mammoth Cave hired a surveyor, Edmond Lee, to survey and map and profile the main cave passages. Stephen Bishop, a …

The Evolution Of Cave Mapping And Cartography, Pat Kambesis Oct 2008

The Evolution Of Cave Mapping And Cartography, Pat Kambesis

Mammoth Cave Research Symposia

“Does it go?” Is the initial question that has inspired many a cave explorer to push the extent of a cave system. But the answer only brings more questions…how far, how long, how deep does it go? During the exploration process, as a cave system reveals its complexity, the questions also change – what is the cave’s relationship to the surface, and to surrounding caves? What are the features and obstacles that the cave contains? Those involved in cave exploration know that the only way to answer these questions is with systematic documentation in the form of cave and surface …

Microtextural Constraints On The Interplay Between Fluidrockreactions And Deformation, Alexis K. Ault, Jane Selverstone Oct 2008

Microtextural Constraints On The Interplay Between Fluidrockreactions And Deformation, Alexis K. Ault, Jane Selverstone

Geosciences Faculty Publications

Schists from two mylonitic localities in the footwall of a low-angle normal fault in the eastern Alps record different degrees of embrittlement during exhumation, depending on the extent to which fluid–rock reactions proceeded. At one site, graphitic schists preserve textural evidence for two metamorphic reactions that modified XCO2XCO2 and/or fluid volume: (1) reaction between graphite and aqueous fluid that increased XCO2XCO2 without changing the molar amount of fluid, and (2) replacement of titanite by rutile, calcite, and quartz. The latter reaction involved net consumption of increasingly CO2-rich fluid. Areas where the first reaction proceeded are associated with abundant Mode I …


Water Quality Impacts From Agricultural Land Use In Karst Drainage Basins Of Sw Kentucky And Sw China, Chris Groves, Ted Baker Sep 2008

Water Quality Impacts From Agricultural Land Use In Karst Drainage Basins Of Sw Kentucky And Sw China, Chris Groves, Ted Baker

Earth, Environmental, and Atmospheric Sciences Faculty Publications

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes, and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into karst subsurface fluvial systems are often very similar to the concentrations surfacing at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be given to water quality impacts …


Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan Sep 2008

Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan

Earth, Environmental, and Atmospheric Sciences Faculty Publications

A standard planar Kernel Density Estimation (KDE) aims to produce a smooth density surface of spatial point events over a 2-D geographic space. However, the planar KDE may not be suited for characterizing certain point events, such as traffic accidents, which usually occur inside a 1-D linear space, the roadway network. This paper presents a novel network KDE approach to estimating the density of such spatial point events. One key feature of the new approach is that the network space is represented with basic linear units of equal network length, termed lixel (linear pixel), and related network topology. The use …

Direct Evidence From Anisotropy Of Magnetic Susceptibility For Lateral Melt Migration At Superfast Spreading Centers, R. J. Varga, Andrew J. Horst, J. S. Gee, J. A. Karson Aug 2008

Direct Evidence From Anisotropy Of Magnetic Susceptibility For Lateral Melt Migration At Superfast Spreading Centers, R. J. Varga, Andrew J. Horst, J. S. Gee, J. A. Karson

Natural Resources and Earth Sciences Faculty Research

Rare, fault‐bounded escarpments expose natural cross sections of ocean crust in several areas and provide an unparalleled opportunity to study the end products of tectonic and magmatic processes that operated at depth beneath oceanic spreading centers. We mapped the geologic structure of ocean crust produced at the East Pacific Rise (EPR) and now exposed along steep cliffs of the Pito Deep Rift near the northern edge of the Easter microplate. The upper oceanic crust in this area is typified by basaltic lavas underlain by a sheeted dike complex comprising northeast striking, moderately to steeply southeast dipping dikes. Paleomagnetic remanence of …


A Microanalytical Approach To Understanding The Origin Of Cumulate Xenoliths From Mauna Kea, Hawaii, Megan Pickard Aug 2008

A Microanalytical Approach To Understanding The Origin Of Cumulate Xenoliths From Mauna Kea, Hawaii, Megan Pickard

Theses and Dissertations

Cumulate xenoliths erupted with alkalic hawaiite lavas from a postshield cinder cone on Mauna Kea, Hawaii include a variety of mafic and ultramafic rock types. Previous studies of major and trace element compositions of minerals in the xenoliths are interpreted to show transitional to alkalic magma parentages from the postshield stage, although any orthopyroxene-bearing xenoliths are considered to have tholeiitic parents. Major element compositions minerals were analyzed using the electron microprobe and trace element compositions of clinopyroxene grains were analyzed by laser ablation inductively coupled plasma mass spectrometry. In this study, major element compositions of clinopyroxene, olivine and plagioclase grains …


Magmatic Sulfur And Chlorine Abundances At Stromboli, Italy And Their Role In The Formation Of Vesicle-Hosted Metal Alloys, Nichelle Lynn Baxter Aug 2008

Magmatic Sulfur And Chlorine Abundances At Stromboli, Italy And Their Role In The Formation Of Vesicle-Hosted Metal Alloys, Nichelle Lynn Baxter

Theses and Dissertations

Strand et al. (2002) discovered small metal alloy grains rich in Cu, Co, and Sn (maximum size 150 µm) in vesicles of lava from Kilauea Volcano. These alloys are also found in basaltic rocks of several Italian volcanoes. To better understand the origin of these metal-rich grains, bombs from Stromboli Volcano were examined. Two bomb types were collected from Stromboli: pumiceous bombs and scoriaceous bombs. Bulk rock trace element geochemistry indicates that there are no significant differences in Cu, Co, or Sn (the three major components of the metal alloys) between the pumiceous and scoriaceous bombs. Comparison of olivine melt …


Magnetic Ordering Phase Transitions Of Gd2sn2o7, Gordon Tam, Andrew Cornelius, Daniel Antonio Aug 2008

Magnetic Ordering Phase Transitions Of Gd2sn2o7, Gordon Tam, Andrew Cornelius, Daniel Antonio

Undergraduate Research Opportunities Program (UROP)

Pyrochlores with magnetic rare earth ions are a topic of interest due to unusual results brought about by their high degree of geometrical frustration. The lattice structure prevents the magnetic spin interactions from finding a single minimum energy state, which leads to a nonzero residual entropy[1]. By analyzing the heat capacity at low temperatures, the type of magnetic interaction can be determined and the temperatures at which long-range magnetic ordering and magnetic field induced splitting of energy states occur.

A Study Of Nife(X)Cr(2-X)O4 By Laser Micro-Raman Spectroscopy, Lucas Wilson, Markus Vasquez, John Farley, Allen L. Johnson, Brian D. Hosterman

Undergraduate Research Opportunities Program (UROP)

Standards of spinels, composed of two metals and oxygen with the formula AB2O4, are being created with known composition to identify spinels in samples of unknown composition by comparison with the spectra obtained from the standards. Laser micro-Raman spectroscopy allows the identification of chemical species based on their unique vibrational modes. The degree to which spinels of varying composition can be identified will be determined. This will aid in the study of the corrosion of steel by liquid metal. Spinels are a likely component of the oxide layer. Understanding the composition of the products of corrosion leads to an understanding …


Pre-Eruptive Conditions Of The Oligocene Wah Wah Springs Tuff, Southeastern Great Basin Ignimbrite Province, Kurtus Steven Woolf Aug 2008

Pre-Eruptive Conditions Of The Oligocene Wah Wah Springs Tuff, Southeastern Great Basin Ignimbrite Province, Kurtus Steven Woolf

Theses and Dissertations

The Wah Wah Springs Tuff (30.0 Ma) is one of several very large volume ash-flow tuffs (>3200 km³ of erupted magma) that were emplaced near the peak of the flare-up of activity in the Great Basin ignimbrite province of western North America. It can be characterized as a "monotonous intermediate" ignimbrite because of its intermediate concentrations of silica (~63 to ~70 wt. %), apparent uniform chemical and mineralogical characteristics, and crystal-rich nature (32 ± 10 % phenocrysts on a dense rock basis). The major phase assemblage found throughout deposit is similar to other monotonous intermediates with a few exceptions …


Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea Aug 2008

Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea

Earth, Environmental, and Atmospheric Sciences Faculty Publications

The state of Florida is blessed with the highest density of large springs in North America and hundreds of smaller springs where the water from limestone aquifers returns to the surface (Scott et al., 2004). Spectacular underwater caves supply water to these springs. Lesser known are the equally fantastic air-filled caves of Florida and South Georgia (Florea, 2006; Lane, 1986). This paper features these underwater and airfilled caves, explores the impact of changes in sea level on karst in this near-coastal environment, and establishes several geologic and hydrologic characteristics that distinguish karst in the limestones of the southeast from karst …


Controls On Longitudinal Profiles In Headwater Rivers Of The Waipaoa Basin, North Island, New Zealand, David M. Livingston Aug 2008

Controls On Longitudinal Profiles In Headwater Rivers Of The Waipaoa Basin, North Island, New Zealand, David M. Livingston

All-Inclusive List of Electronic Theses and Dissertations

The longitudinal profiles of the adjacent Mangatu and Upper Waipaoa Rivers, of the Waipaoa basin of the North Island of New Zealand, differ in their form despite their similarity in size and that they flow over comparable bedrock. AdditionaJly, both basins have experienced an increase in sediment supply following deforestation during the 19th and 20th centuries. This research addresses how the deviations in the long profiles of the Mangatu and Upper Waipaoa Rivers have arisen and what effect the increased sediment loading has had on their form. Using methods similar to those of Hack (1957), who found that in same …

This study examines a paleolandscape model that focuses on alluvial landforms that date to the Late Pleistocene and Early Holocene in Knob Creek bottom of the lower Ohio River valley. The study tests and refines a landscape model based on geoarchaeological data from the Caesars Archaeological Project. Analysis centers on the relationship between late Wisconsin and early Holocene Landform Sediment Assemblages (LSA), including early paleochannels. For this analysis a series of soil cores was extracted from the LSA understudy and described using standard USDA terminology. Additional analysis included particle size analysis using a hydrometer to determine textural composition of core …


Influence Of Bioirrigation On Metal Distribution Within Burrows, Terri Shattuck Aug 2008

Influence Of Bioirrigation On Metal Distribution Within Burrows, Terri Shattuck

Masters Theses

Bioirrigation is the increase of solute transport resulting from introduction of oxygenated water from the surface into the more reduced environment deep within the burrow. Fe and Mn hydr-(oxides) accumulate on burrow margins in response to the oxygen flux into suboxic porewaters. This has been shown to trap trace metals (Harding and Risk, 1986; Tessier and Campbell, 1988; Tessier et al., 1979, 1982). The diagenesis, mobility, and transport of metals contribute to the bioavailability of metals in the environment possibly to the extent of harming ecosystems; especially in coastal areas with buried waste. This study assesses Fe and trace metal …

The Mayan Ice Cap: Glacial Geology And Paleoclimate Of The Northern Guatemalan Highlands, Alex Joseph Roy

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Sierra de los Cuchumatanes region of the northern Guatemalan highlands supported a large plateau ice cap with an area of -40 km2 along with a group of 5 cirque glaciers -1 to 2 km2 during the local last glacial maximum (LLGM). A comprehensive mapping reconstruction of the northern Guatemalan highlands is presented here, including glacial geology and an estimate of maximum ice limits from physical evidence and computer modeling. The glacial geologic map was produced via field mapping with global positioning system (GPS) surveying combined with aerial stereo photographic and topographic map analysis. This new field work on moraine …


Origin Of Tunnel Valley And Esker Assemblages In The Saginaw Lobe, Barry County, Michigan, Caleb J. Woolever Aug 2008

Origin Of Tunnel Valley And Esker Assemblages In The Saginaw Lobe, Barry County, Michigan, Caleb J. Woolever

Masters Theses

Surficial mapping, borehole analysis, and ground penetrating radar surveys are used to reconstruct conditions leading to the formation of tunnel valley and esker networks within the Dowling 7 .5 minute quadrangle. The relationship between tunnel valleys and eskers has important implications on the subglacial hydrology beneath the Saginaw Lobe of the Laurentide Ice Sheet.

Surficial mapping reveals northeast-southwest trending tunnel valleys, some containing eskers of the same orientation, in hummocky topography mapped as the Saginaw Kalamazoo Moraine. A borehole hole drilled through one such tunnel valley and esker pair reveals sand and gravel fining upwards to fine sand. Stratigraphy suggests …
