Ghosts of Oceans Past: Analysis of Microfossils from Deep Sea Sediments
(2009-09-30)This research focuses on the analysis of microfossils from deep-sea sediments. I am investigating a series of deep-sea sediment cores from the South Pacific. The cores are a vertical timeline of sedimentation, with each ... -
Paleotemperature Proxies: Validation and Applications in the Atlantic and Pacific Oceans
(2015-07-27)Paleotemperature proxies enable scientists to reconstruct past ocean temperatures from sediment recovered in deep-sea cores. This dissertation takes an in-depth look at two proxies, Mg/Ca ratios of planktonic foraminifera ... -
Stable Isotope Characterization and Proxy Records of Hypoxia-Susceptible Waters on the Texas-Louisiana Shelf
(2012-02-14)Hypoxia, with dissolved oxygen levels < 1.4 ml L-1, is a recurring summer feature of Louisiana shelf bottom waters. Stable isotope characterization (delta^18O and delta D) of surface waters over the hypoxic zone shows a ...
