Book Description
Biogeochemistry of Sulfur Isotopes in Crystal Lake, Clark County, West-Central Ohio
Author: Amanda Lynn Meyer
Publisher:
ISBN:
Category : Lakes
Languages : en
Pages : 95
Book Description
Crystal Lake showed distinct biogeochemical patterns, which were governed by thermal stratification, photosynthesis, and sulfur redox processes. Field parameter measurements and water and Planktothrix rubescens samples were collected in May, August, and October, 2013 at the deepest point in the lake, to better understand these processes. At the metalimnion–hypolimnion boundary, P. rubescens produced chlorophyll and turbidity maxima. Photosynthesis produced oxygen-rich and nutrient-poor surface waters. The decay of organic matter produced anoxic, nutrient-rich water in the hypolimnion. Sulfate concentrations were high in the epilimnion and metalimnion, with a maximum at the layer of P. rubescens, and decreased with depth in the hypolimnion. Sulfide was absent in the epilimnion and metalimnion and increased with depth in the hypolimnion. Sulfur isotopic composition changed with depth in the hypolimnion due to Rayleigh Fractionation. It can be concluded that P. rubescens play a major role in the sulfur cycle and sulfur isotopic composition changes.

Lectures in Isotope Geology
Author: E. Jäger
Publisher: Springer Science & Business Media
ISBN: 3642671616
Category : Science
Languages : en
Pages : 507
Book Description
Our colleagues from the French-speaking parts of Switzerland - the Suisses romands - and above all the committee of the 3rd Cycle, e Earth Sciences (3 Cycle, Sciences de la Terre) honored us by asking us to give a course on Isotope Geology for the year 1977. The course, entitled Evaluation et Interpretation des Donnees Isotopiques (eval uation and Interpretation of Isotopic Data), was intended to inform earth scientists, graduate and postgraduate, from the western Swiss Universities on the subject of Isotope Geology. Such courses usually consist of two parts: lectures and excursions. Thus, in March 1977, we gave such a two-week course at the Miner alogical Institute of the University of Berne. The first week was devoted essentially to the methods of dating, the second week to the behavior of stable isotopes. In July 1977, on the occasion of an excursion to the Central and Western Alps, we were able to demonstrate our results. Guest professors were invited to make contributions to the course.

Sediments, Diagenesis, and Sedimentary Rocks
Author: F.T. Mackenzie
Publisher: Elsevier
ISBN: 0080525229
Category : Science
Languages : en
Pages : 448
Book Description
This volume covers the formation and biogeochemistry of a variety of important sediment types from their initial formation through their conversion (diagenesis) to sedimentary rocks. The volume deals with the chemical, mineralogical, and isotopic properties of sediments and sedimentary rocks and their use in interpreting the environment of formation and subsequent events in the history of sediments, and the nature of the ocean-atmosphere system through geological time. Reprinted individual volume from the acclaimed Treatise on Geochemistry, (10 Volume Set, ISBN 0-08-043751-6, published in 2003). Comprehensive and authoritative scope and focus Reviews from renowned scientists across a range of subjects, providing both overviews and new data, supplemented by extensive bibliographies Extensive illustrations and examples from the field
