Field Guide To Big Bone Lick, Kentucky: Birthplace Of American Vertebrate Paleontology, Glenn W. Storrs, H Gregory Mcdonald, Eric Scott, Robert A. Genheimer, Stanley E. Hedeen, Cameron E. Schwalbach

Special Publication--KGS

Big Bone Lick is the birthplace of vertebrate paleontology in the Western Hemisphere and has a long and celebrated history in the exploration of the American colonial frontier and of the early United States. Notable European scientists of the 18th century such as Buffon, Cuvier, and Hunter discussed the fossils found there. Prominent Americans of the time, such as Boone, Washington, Franklin, and Jefferson are also part of the site’s history. It is the type locality for several extinct late Pleistocene megafaunal mammals, most notably the iconic American Mastodon, who were attracted to the area by salt licks dictated by …

Ucg Pilot Tests In Eu Countries: A Review Of History And Progress, Jin Lili, Yang Lei, Wu Yarong, Wang Xiaofang, Yi Tongsheng, Qin Yong

Coal Geology & Exploration

Underground coal gasification (UCG) is an important way of transforming China’s coal energy structure. European Union (EU) countries explored UCG for over 80 years, and their rich experience can be used as a reference for promoting UCG industrialization in China. The UK prepared for UCG pilot tests for the first time in the world. From 1944 to 2014, based on the experience of the former Soviet Union and the United States, EU countries successively implemented at least 12 UCG pilot test projects in three stages, making important contributions to the progress in UCG technologies. They invented the blind-hole method and …

Effects Of Landscape Structure On Plants Species Richness In Small Grassland Remnants In Two Different Landscapes, S. A. O. Cousins, O. Eriksson

IGC Proceedings (1997-2023)

There is an increasing interest in using the landscape as the operational scale in many ecological studies. Current species richness in the landscape may be explained by past land use, and habitats may harbour species favoured by an environment that no longer exists. In this study we have included both a landscape scale and a temporal scale. The objective was to explain species pattern and the effect of isolation, habitat size and surrounding land use, and past land use change, on small grassland remnants in rural landscapes.

Interdisciplinary Studies Masters Degree In Anthropological & Science Based Education, Robert Porter

Electronic Theses, Projects, and Dissertations

The goal of this project is to develop anthropological and science-based curricula that will emphasize a place-based approach while actively engaging students in their education. I developed two curricula for elementary aged students in San Bernardino. The first curriculum was based anthropologically on the local history of indigenous groups and early San Bernardino history. The second was based on paleontology here in California with a focus on dinosaurs and fossils.

To improve and validate the curricula I sent the examples to educational experts and had them critique the lessons and information provided. Then I used their input to improve the …

Structural History Of The Bald Mountain Mining District, Nevada, Usa, David Paul Ryan

WWU Graduate School Collection

The Bald Mountain Mining district, like much of central Nevada, has experienced a complex deformation history. The mining district is considered here as a southern extension of the well-studied Carlin trend of gold deposits to the north. In order to gain a better understanding of how the Bald Mountain Mining District structural style relates to other structural models developed to the north in the Carlin trend, I completed a mapping and structural domain analysis in the district, with a focus on the North Mooney basin area where a high spatial concentration of Carlin-type gold deposits occur. The identification of structural …

International Grassland Congress Outlook – A Historical Review And Future Expectations, L. R. Humphreys

IGC Proceedings (1997-2023)

Features of the history of the International Grassland Congress are mentioned. Aspects of a number of failed themes in grassland science are described with respect to molecular biology, intensive systems of ruminant production, carbohydrate use in plant growth, plant succession and range condition, and stocking method. Future expectations are focused on meeting a balance of objectives, maintaining reductionist science, taking new initiatives in plant improvement and in the development of animal production systems, and reducing barriers to international trade. The adoption of grassland science depends upon the growth of new learning, especially through cyclical interaction between scientists and farmers.

The History Of The International Grassland Congress 1927-2020, S. Ray Smith, Vivien G. Allen, Roger Wilkins, Garry D. Lacefield

Plant and Soil Sciences Presentations

Grasslands cover 27% of the world’s land area and 70% of agricultural land. They form an important foundation for agriculture and livestock husbandry and contribute to the livelihoods of more than 800 million people. The International Grassland Congress (IGC) began as a meeting of a small group of forage researchers in Europe in 1927. It has now expanded into a gathering held every 3-5 years with over 1000 delegates from 80+ countries who represent research, extension, and primary production. The newly released IGC history provides not only an overview of the IGC Congress over the last 93 years, but highlights …

Radium Isotopes As Submarine Groundwater Discharge (Sgd) Tracers: Review And Recommendations, J. Garcia-Orellana, V. Rodellas, Joseph Tamborski, M. Diego-Feliu, P. Van Beek, Y. Weinstein, M. Charette, A. Alorda-Kleinglass, H.A. Michael, T. Stieglitz, J. Scholten

OES Faculty Publications

Submarine groundwater discharge (SGD) is now recognized as an important process of the hydrological cycle worldwide and plays a major role as a conveyor of dissolved compounds to the ocean. Naturally occurring radium isotopes (Ra-223, Ra-224, Ra-226 and Ra-228) are widely employed geochemical tracers in marine environments. Whilst Ra isotopes were initially predominantly applied to study open ocean processes and fluxes across the continental margins, their most common application in the marine environment has undoubtedly become the identification and quantification of SGD. This review focuses on the application of Ra isotopes as tracers of SGD and associated inputs of water …

Moonmilk As A Human And Veterinary Medicine: Evidence Of Past Artisan Mining In Caves Of The Austrian Alps, Christoph Spötl

International Journal of Speleology

The use of moonmilk for medical and other purposes in the Alps is documented since the 16^th century. This article reviews speleological reports and sparse historical accounts about the extraction of moonmilk from 18 caves in the Eastern Alps of Austria in an artisan mining style. One such example from a cave in Tyrol is documented in detail, where moonmilk was mined until the beginning of the 20^th century and which, due to its remote location, uniquely preserved traces of both the mining and processing style.

Paleoimagery: The Artistic Restoration Of Dinosaurs And Prehistoric Life, Colin Mcnulty

Honors Projects

My purpose in creating this paper is to research a holistic view of paleontological illustration (also called paleoimagery or paleoart). A thorough history of paleoimagery is outlined from its roots in biblical illustration in the 17^th and 18^th centuries approaching the modern day. A two-fold examination of the utility of art to communicate science and its use within the science of paleontology is also given. This includes discussions of the specific components of art pieces that help them to successfully communicate scientific ideas and examples of how paleoimagery contributes to paleontology. The author then outlines the conception and …

Underground Fieldwork – A Cultural And Social History Of Cave Cartography And Surveying Instruments In The 19th And At The Beginning Of The 20th Century, Johannes Mattes

International Journal of Speleology

At the turn of the 20^th century, the practical examination of caves went through a radical change. Governmental organizations and private clubs were founded in an attempt to establish speleology as an independent academic subject. In contrast to earlier cave visitors, travelers began entering underground areas and attributing the names of “explorers” or “researchers” to themselves. Fieldwork—especially cave surveying and cartography—became common practice in speleology and such work provided important clues on speleogenesis, which was a controversial issue in the first half of the 20^th century. Due to the fact that speleologists began separating themselves from ordinary …

Vegetation Controls On Weathering Intensity During The Last Deglacial Transition In Southeast Africa, Sarah J. Ivory, Michael M. Mcglue, Geoffrey S. Ellis, Anne-Marie Lézine, Andrew S. Cohen, Annie Vincens

Earth and Environmental Sciences Faculty Publications

Tropical climate is rapidly changing, but the effects of these changes on the geosphere are unknown, despite a likelihood of climatically-induced changes on weathering and erosion. The lack of long, continuous paleo-records prevents an examination of terrestrial responses to climate change with sufficient detail to answer questions about how systems behaved in the past and may alter in the future. We use high-resolution records of pollen, clay mineralogy, and particle size from a drill core from Lake Malawi, southeast Africa, to examine atmosphere-biosphere-geosphere interactions during the last deglaciation (~ 18-9 ka), a period of dramatic temperature and hydrologic changes. The …

The Historical Role Of Base Maps In Soil Geography, Bradley A. Miller, R. J. Schaetzl

Bradley A Miller

Soil mapping is a major goal of soil science. Soil maps rely upon accurate base maps, both for positional reference and to provide environmental data that can assist in the prediction of soil properties. This paper reviews the historical development of base maps used for soil mapping, and evaluates the dependence of soil mapping on base maps. The availability of geographic technology for producing base maps has both constrained and directed the geographic study of soil. The lack of accurate methods for determining location limited early geographic descriptions of soils to narratives, or to listings of attributes for property-based map …

Cova Des Pas De Vallgornera, (Mallorca, Spain): History Of Exploration And Cave Description, Antoni Merino, Antoni Mulet, Guiem Mulet, Antoni Croix, Anders Kristofersson, Francesc Gràcia, Miquel A. Perelló

International Journal of Speleology

The Cova des Pas de Vallgornera lies in the Llucmajor municipality, in southern Mallorca, and is the longest cave in the Balearic Islands. Currently its surveyed length is over 74,000 metres, including more than 17,000 of underwater extensions. The cave was discovered accidentally in 1968, but it was in 2004 when a major breakthrough shed light on its real extension and importance. The cave roughly shows two tiers of passages, apart from the underwater extensions, the first one is between 7 and 11 m above the mean sea level, the second one is about at the water table level.

Origin And Provenance Of Spherules And Magnetic Grains At The Younger Dryas Boundary, Yingzhe Wu, Mukul Sharma, Malcom A. Lecompte, Mark N. Demitroff, Joshua D. Landis

Dartmouth Scholarship

One or more bolide impacts are hypothesized to have triggered the Younger Dryas cooling at ∼12.9 ka. In support of this hypothesis, varying peak abundances of magnetic grains with iridium and magnetic microspherules have been reported at the Younger Dryas boundary (YDB). We show that bulk sediment and/or magnetic grains/microspherules collected from the YDB sites in Arizona, Michigan, New Mexico, New Jersey, and Ohio have (187)Os/(188)Os ratios ≥1.0, similar to average upper continental crust (= 1.3), indicating a terrestrial origin of osmium (Os) in these samples. In contrast, bulk sediments from YDB sites in Belgium and Pennsylvania exhibit (187)Os/(188)Os ratios <<1.0 and at face value suggest mixing with extraterrestrial Os with (187)Os/(188)Os of ∼0.13. However, the Os concentration in bulk sample and magnetic grains from Belgium is 2.8 pg/g and 15 pg/g, respectively, much lower than that in average upper continental crust (=31 pg/g), indicating no meteoritic contribution. The YDB site in Pennsylvania is remarkable in yielding 2- to 5-mm diameter spherules containing minerals such as suessite (Fe-Ni silicide) that form at temperatures in excess of 2000 °C. Gross texture, mineralogy, and age of the spherules appear consistent with their formation as ejecta from an impact 12.9 ka ago. The (187)Os/(188)Os ratios of the spherules and their leachates are often low, but Os in these objects is likely terrestrially derived. The rare earth element patterns and Sr and Nd isotopes of the spherules indicate that their source lies in 1.5-Ga Quebecia terrain in the Grenville Province of northeastern North America.
