Evaluation Of Foraminiferal Trace Element Cleaning Protocols On The Mg/Ca Of Marine Ostracod Genus Krithe, William Gray, Jonathan Holmes, Amelia E. Shevenell

Marine Science Faculty Publications

The Mg/Ca of calcite from the marine ostracod genus Krithe may be an important tool for reconstructing past changes in oceanic bottom water temperature (150–4000 m water depth). Rigorous cleaning procedures, routinely used to remove clays, organic matter and Fe–Mn oxyhydroxide coatings in trace element studies of foraminifera, are not regularly applied to marine ostracods despite the potential for Mg contamination. Here we apply standard oxidative and reductive foraminiferal cleaning procedures to core top Krithe pernoides valves from boxcore OCE205-50BC (26.23°N, 77.7°W, 817 m water depth) to evaluate the effects of contamination on Mg/Ca ratios and assess the impact of …

Time, Money, And Melting Ice: Proposal For A Coopertive Study Of The World’S Cave Ice In A Race Against Climate Change, George Veni, Lewis Land, Aurel Perşoiu

The International Workshop on Ice Caves

Climate change is a global phenomenon that is melting and threatening to melt ice deposits in many of the world’s ice caves. The National Cave and Karst Research Institute of the USA is concerned that major and important paleoclimate and paleoenvironmental records stored in cave ice will soon be lost, and is proposing an international collaborative effort to overcome funding and logistical challenges to sample and analyze at least a representative collection of ice from several regions before further melting occurs.

Some New Potential Subterranean Glaciation Research Sites From Velebit Mt. (Croatia), Neven Bočić, Nenad Buzjak, Zoltan Kern

The International Workshop on Ice Caves

Despite the frequent reports about their shrinkage detailed survey of the major subterranean ice deposits is still lacking in Croatia. Here we present cave maps and detailed description of cave ice accumulation from five caves of the Velebit Mt. Morphological constraints allowed ice volume estimation for four of them. Ice volumes were estimated as ~1500 m³ at the Gavranova Pit in 1999, 100 m³ at Štirovača ice cave in 1987, 150 m³ at Japagina 3 in 2000, 1500 m³ at Kugina ice cave in 2004. These new records provide reference data for future studies to evaluate …

Climate Study In An Abandoned Auto Tunnel In Alaska, Usa, Andreas Pflitsch, David Holmgren

The International Workshop on Ice Caves

An abandoned auto tunnel in south central Alaska in an elevation of 118 m above sea level seemed to be a perfect laboratory for studying the evolution of ice speleothems in a yearly cycle. More than 1,500 ice forms like stalagmites, stalactites, columns in various shape and arrangements, developed in just 2 month to a high up to 6 meters and lasted for another 5 to 6 month. In October just the remains of the melted ice in rings and rectangular patterns of a white powder could be found. Unfortunately the mostly sealed tunnel was opened in January 2014 by …

Internal Drainage Of Glaciers And Its Origin, Bulat R. Mavlyudov

The International Workshop on Ice Caves

Ways of occurrence of elements of an internal drainage of glaciers and also origin of internal drainage systems as a whole are considered. It is shown that elements of an internal drainage can be formed either on the base of fissures and crevasses or by incision of water streams into ice from glacier surface. The basic way of glacier drainage is formed on the base of sliding plane which is formed closely to glacier bed and smooth all roughnesses of the bed. Spreading of water on the surface of this plane during spring time forms not effective drainage system however …

Constraining Holocene Hydrological Changes In The Carpathian–Balkan Region Using Speleothem Δ18O And Pollen-Based Temperature Reconstructions, V. Drăguşin, M. Staubwasser, D. L. Hoffmann, V. Ersek, Bogdan P. Onac, D. Vereş

School of Geosciences Faculty and Staff Publications

ere we present a speleothem isotope record (POM2) from Ascunsă Cave (Romania) that provides new data on past climate changes in the Carpathian–Balkan region from 8.2 ka until the present. This paper describes an approach to constrain the effect of temperature changes on calcite δ¹⁸O values in stalagmite POM2 over the course of the middle Holocene (6–4 ka), and across the 8.2 and 3.2 ka rapid climate change events. Independent pollen temperature reconstructions are used to this purpose. The approach combines the temperature-dependent isotope fractionation of rain water during condensation and fractionation resulting from calcite precipitation at the …

History Of Numeracy Education And Training For Print Journalists In England, Steven Harrison

Numeracy

If the history of journalism education has been a footnote to accounts of the profession’s development, then the history of numeracy training for journalists must be considered a footnote to a footnote. Despite the universally acknowledged centrality of numbers to a clear understanding of the world, many journalism students and entrants are proudly number-phobic; it is even suggested that an aversion to maths is a key reason why some choose journalism as a career. This study traces the development of numeracy education for journalists in England. It is only with the incipient professionalisation of journalism from the mid-19th century that …

A Conservation Status Index, As An Auxiliary Tool For The Management Of Cave Environments, Christiane Ramos Donato, Adauto De Souza Ribeiro, Leandro De Sousa Souto

International Journal of Speleology

The conservation of the Speleological Heritage involves bioecological, geomorphological and anthropogenic studies, both from inside the caves and from the external environments that surround them. This study presents a method to rank caves according to their priority for conservation and restoration. Nine caves were evaluated: indicators related to the environmental impacts and the vulnerability status presented by those caves (intrinsic features) and the values scored in a ‘Cave Conservation Index’ (CCI) were established. We also used a rapid assessment protocol to measure cave vulnerability for prioritization of conservation/restoration actions (RAP-cr) comparing natural cavities with the same lithology, due …

Managing Regional Water Resources Amidst Rapid Urbanization In Southwest Florida: A Case Study, Nicole Owusua Caesar

USF Tampa Graduate Theses and Dissertations

Experts and organizations involved in freshwater resources management have emphasized the importance of long-term urban resource planning and management that considers the tight coupling which exists between human - nature - technology systems. The resistance of contemporary urban growth efforts to consider resource carrying capacities and ecosystem requirements has led to costly unintended consequences including the deterioration of natural capital and their associated ecosystem services, and the degradation of water resource flows. As these problems continue to worsen, resource experts have called for the development of a new water resource management paradigm inclusive of various sustainability criteria.

"Wake Up The Knowledge That You Have": An Assessment Of Community Food Security In Fellsmere, Florida, Susan Marie Tyler

USF Tampa Graduate Theses and Dissertations

In the global industrial agricultural system many people lack access to high-quality nutritious foods and food production techniques are often inefficient and reliant on harsh chemical inputs. While numerous strategies exist to address the disparities present in the global food system, increasingly researchers and practitioners are looking to local food systems for solutions to strengthen community food security (CFS). CFS emphasizes small-scale production strategies such as farmer's markets, community gardens, and consumer supported agriculture. As these efforts evolve, research is needed to understand how these strategies affect communities. To explore a local CFS initiative, qualitative data were collected from community …
