Floodplain Deposits, Channel Changes And Riverbank Stratigraphy Of The Mekong River Area At The 14th-Century City Of Chiang Saen, Northern Thailand., Spencer H. Wood, Alan D. Ziegler, Tharaporn Bundarnsin
Geosciences Faculty Publications and Presentations
Riverbank stratigraphy and paleochannel patterns of the Mekong River at Chiang Saen provide a geoarchaeological framework to explore for evidence of Neolithic, Bronze-age, AD 5th Century Yonok and AD 14-16th Century Lan Na Cultures. Typical bank stratigraphy charted on the Thailand side is imbricate cobble gravel overlain by 5-10 m of reddish-brown sandy silt. The silt section is composed chiefly of ½ to 2-m thick layers of massive silt without paleosols interpreted as near-channel floodplain and gently-inclined levee deposits laid down by episodic, infrequent, large floods. The surface soil is dark-brown clay loam (La Na time. Brick ruins of 14-16th …

Mammoth Cave Research Symposia
One hundred years ago, a young German engineer named Max Kämper, came as a visitor to Mammoth Cave. He became so enchanted with the cavern he obtained permission to map the vast system. For the next eight months Max, along with assistance from cave guide Ed Bishop, meticulously put together a highly detailed and accurate map revealing more of the cave than ever before. He probably never realized his work would be admired by generations to follow. Some admire its artistic expression of the cave. Others see beauty in its precision. Ultimately, it has become the iconic map for generations …

Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons
Mammoth Cave Research Symposia
Serving as guides and explorers at Mammoth Cave partially rescued four men from the obscurity of enslavement. Stephen Bishop, Materson Bransford, Nicholas Bransford and a young man named Alfred all had their very existence documented in the written journals and diaries of various nineteenth century Mammoth Cave visitors. They were physically described, their personalities contemplated, their intelligence gauged, their dialects imitated. At least one abolitionist characterized Stephen Bishop as a charismatic natural leader who could govern the citizenry of freed men in Liberia, should he choose to relocate there.

Mammoth Cave Research Symposia
Twenty-seven year old engineer Max Eduard Kämper arrived in America at 4:00 pm on May 16, 1907 and was greeted by a thunderstorm. His presumed goals were to study American manufacturing methods, learn English, and enrich himself musically. New York had so many German immigrants at the time that German was the second most common language spoken in the city. He stayed at the Belvedere House at the corner of 4th Avenue and 18th Street, and the next day visited acquaintances in Newark. He visited New York landmarks and May 20 visited the famed Hippodrome theater. He moved on May …

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
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 …

The Puzzling Mr. Janin And Mammoth Cave Management, 1900-1910, Katie Algeo
Mammoth Cave Research Symposia
Albert Covington Janin was the key architect of tourism development at Mammoth Cave for two decades at the start of the twentieth century, yet little has been written about his tenure. This paper explores his background and accomplishments for the period 1900 to 1910 as an initial attempt to understand his contributions to Mammoth Cave. Material about his activities in relation to Mammoth Cave is synthesized from primary sources in the archival collections of the Huntington Library (HL) of San Marino, California, and the Historical Society of Washington, DC (HSW).

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 …

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 …

Earth and Soil Sciences
Serpentinitic soils often contain high concentrations of heavy metals, including chromium (Cr) and nickel (Ni). Soils derived from serpentine parent material are used for agricultural purposes throughout San Luis Obispo County, CA. This study was undertaken to determine the amount of total and bioaccessible Cr and Ni in soil and vine tissue from a vineyard planted on soils derived from serpentine geology. Eighteen soil and plant samples were collected from different slope position and vine types (syrah and chardonnay). Soil samples were collected from about 0 to 30 cm at the base of the vines and 15 to 20 leaf …

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 …

Variations In Stomatal Traits Of 14 Bornean Tree Species Growing On Soils With Different Moisture Contents In Lambir Hills National Park, Whitney Logan Cannon
Department of Environmental Studies: Undergraduate Student Theses
The goal of this study was to look at variations in stomatal traits of tree species on soils with different moisture contents and fertility at Lambir Hills National Park. Stomates are important structures on the surface of leaves that mediate conduction of moisture and gassesin and out of the leaf. If stomatalt raits are important for regulation, then there should be variation in stomatal traits in regards to their soil specialization.

Faculty Publications
[1] A 9‐year time series of water column and sediment trap measurements was used to examine silicon cycling within the anoxic Cariaco Basin. The dynamic hydrographic regime within Cariaco Basin results in strong seasonal changes in nutrient availability and the Si:C:N of sinking particles. Upwelling in early winter injects silicic acid (Si(OH)4= ) and nitrate (NO3−) rich waters into the photic zone which stimulates primary production and results in opal fluxes in excess of 4 mmol Si m−2 d−1. However, even during upwelling, surface waters tend to be depleted (μM) in both Si(OH)4= and NO3− as a result …

Publications (YM)
This is the final report presenting precipitation data collected under task ORD-FYO4-007 “Precipitation Monitoring at Yucca Mountain”. This task acquired data using tipping bucket rain gauges to measure, with known accuracy, the accumulation and timing of precipitation in the vicinity of Yucca Mountain. Operation of the tipping bucket precipitation monitoring network was assumed by the Harry Reid Center for Environmental Studies (HRC) at the University of Nevada, Las Vegas (UNLV) in March of 2001. Precipitation monitoring data collection concluded June of 2008. All data presented in this report were collected during that time.

Hydrological Impact Of The Potential Future Vegetation Response To Climate Changes Projected By 8 Gcms, Clement Alo, Guiling Wang
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
This study uses offline simulations with a land surface model to explore how the future response of potential vegetation to elevated CO2 and attendant climate changes feeds back to influence surface hydrological processes. Climate changes are those projected by eight General Circulation Models (GCMs) under the SRESAlB, and the potential natural vegetation structure corresponding to the Preindustrial control and SRESAlB 2100 climate of the 8 GCMs are simulated by a dynamic global vegetation model integrated to equilibrium. For climate change forcing from each GCM, comparisons are made among three surface hydrology simulations using CLM3.0 driven with different combinations of climate …

Faculty Publications
The spatial density of hydrothermal activity along most mid-ocean ridges is a robust linear function of spreading rate (or magmatic budget), but extreme crustal properties may alter this relationship. In 2005–2006 we tested the effect of thickened crust on hydrothermal activity using high-resolution mapping of plumes overlying the hot spot–affected Galapagos Spreading Center from 95o to 89o42'W (~560 km of ridge crest). Plume mapping discovered only two active, high-temperature vent fields, subsequently confirmed by camera tows, though strong plume evidence indicated minor venting from at least six other locations. Total plume incidence (ph), the fraction of ridge …

On A New Process For Cusp Irregularity Production, Herbert C. Carlson, K. Oksavik, J. Moen
Faculty publications
Two plasma instability mechanisms were thought until 2007 to dominate the formation of plasma irregularities in the F region high latitude and polar ionosphere; the gradient-drift driven instability, and the velocity-shear driven instability. The former mechanism was accepted as accounting for plasma structuring in polar cap patches, the latter for plasma structuring in polar cap sun aligned arcs. Recent work has established the need to replace this view of the past two decades with a new patch plasma structuring process (not a new mechanism), whereby shear-driven instabilities first rapidly structure the entering plasma, after which gradient drift instabilities build on …
