Changes in stable carbon isotopes of methane along a salinity gradient in a hypersaline microbial mat system
(University of Missouri--Columbia, 2007)
The purpose of this study was to examine how the stable carbon isotopes of methane and possible methanogenic substrates change in microbial mat communities as a function of salinity. Microbial mats were sampled from four ...
Structural geology, tectonic geomorphology, and neotectonics of the central Afar Rift, Ethiopia and Djibouti
(University of Missouri--Columbia, 2018)
The central Afar depression offers an opportunity for quantitative analysis of the final stages of continental breakup at a divergent triple junction. Here, Quaternary faulting dissects Plio-Pleistocene flood basalts, ...
Temporal trends in the Holocene: exploring implications for conservation paleobiology through quantitative assessment of marine mollusks
(University of Missouri--Columbia, 2018)
Conservation paleobiology is a relatively new field which applies the theories and analytical tools of paleontology to problems concerning the conservation of biodiversity. The use of data from stratigraphy, sediment or ...
Late cretaceous ocean circulation in the south Atlantic and Pacific oceans
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cooling during the last 15 million years of the Cretaceous is widely believed to have resulted in a reorganization of ocean circulation, with cooler periods being associated...
Atypical planetary lavas: rheological evolution of cooling and crystallizing flows from lunar impact melts and cryovolcanic processes
(University of Missouri--Columbia, 2021)
Volcanism is common to many of the solid planets and moons throughout the solar system. On Earth, volcanic research is mainly targeted at hazard assessment and prediction but volcanism on other worlds helps us understand ...
The effects of volatiles on the viscosity and heat capacity of calc-alkaline basaltic and basaltic andesite liquids
(University of Missouri--Columbia, 2014)
Calc-alkaline basaltic magmas are volumetrically important at continental and island volcanic arcs, yet their thermal and physical properties are poorly described. These basaltic magmas are characteristically hydrous, and ...
