Reconstructing deglacial ocean ventilation using radiocarbon : data and inverse modeling
… the climate system. The ocean is a large reservoir of carbon and heat, however, its role during the deglaciation is still not well understood. In this thesis, I rely on radiocarbon measurements on fossil biogenic carbonates sampled from the seafloor to constrain deglacial ocean ventilation …

Understanding terrestrial organic carbon export : a time-series approach
… investigate distributions of OC source, reservoir age, and chemical structure contained within a single sample, I developed a kinetic model linking RPO-derived activation energy, 13C composition, and radiocarbon content. This tool provides a novel method to fundamentally address the …

Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating
… field variations and to evaluate suggested linkages between geomagnetic field and climate change. The general aim of this thesis is to improve the dating of changes in climate and the geomagnetic field via linking 14C results of closely spaced samples to the 14C calibration curve – the 14C …

Quantitative Ecological and Taphonomic Patterns in Late Cenozoic Mollusk-Dominated Marine Fossil Assemblages
… biases in dating biological specimens ranging in age from modern to thousands of years old. Although such methods are arguably not perfect, error rates of ± a few hundred to few thousand years can be extremely important when considering ecological relationships among both Holocene taxa and …
