Theses and Dissertations
The Arctic Ocean and its marginal seas are key areas for understanding the global climate system. Climate change causes increased terrigenous materials to be carried into the ocean as well as higher production of marine organic matter in the ocean. This study determined the concentrations, distribution, and sources of fatty acids in core sediments from four locations: Stations H32, H30, BarC5 and H24 in the Chukchi Sea, which are in the Arctic Ocean. Fatty acids are valuable tracers of marine or terrigenous inputs and may give evidence to the extent of climate change. Fatty acids were analyzed, characterized using GC-MS …

Theses and Dissertations
The occurrence of harmful algal blooms (HABs) and their impacts on human health and the economy are only expected to worsen in the coming years, mainly due to climate change related factors. In Lake Wateree, SC, a HAB of the species Lyngbya wollei, has been persistent for more than 10 years and is estimated to occupy 60 - 90 km of shoreline. This natural laboratory provided and continues to provide a unique window into the chemistry and microbial ecology of HABs. Work in this dissertation was directed at answering a critical question: are biomass-to-toxin ratios constant in HABs? Initial …
