Abstract Details

2013, Doctor of Philosophy, Ohio State University, Atmospheric Sciences.
Dramatic changes in net accumulation and temperature on the Antarctic Peninsula have been observed over the last century. Ice core-derived proxies provide histories of these variables extending beyond the relatively short instrumental records available for this region. Histories of net annual accumulation and d18O from an ice core drilled to bedrock on the Bruce Plateau in the Antarctic Peninsula provide an additional multi-century record of climate variability in this region. Time series for the period 1750-2009 CE are generated, evaluated for changes over time and compared to other relevant environmental data. Comparisons to satellite and station data are conducted over the relatively short duration of these records. Large scale atmospheric oscillations, such as the Southern Annular Mode and El Niño-Southern Oscillation, are investigated as potential drivers of the observed changes from 1900-2009 CE. Ice core records from other locations are analyzed to provide a larger spatial context for the changes observed on the Antarctic Peninsula from 1750 to 2009 CE. Sulfate in ice cores can originate from sea salt, oceanic biological productivity, volcanic activity, and anthropogenic influences. Different methods are used to distinguish the sulfate contributed by each of these sources and thereby to generate source specific sulfate histories.
