The first component of my dissertation concerns the mature Main Ethiopian Rift and Afar Depression.
Specifically, I assess triggering of seismic activity related to the true fortnightly and fortnightly modulations of diurnal and semidiurnal tides at the East Pacific Rise through a dataset from an Ocean Bottom Seismometer array that was deployed from October 2003 to January 2007.
My dissertation research is a compilation of projects aimed at fine-tuning and exploring the bounds of coral paleoceanographic proxies. Using stable oxygen isotopes from corals off the Pacific coast of Panamá I am reconstructing decadal precipitation patterns to better understand low frequency variability in the Pacific Basin.
In conjunction with the precipitation record, I am studying the viability of coral Ba/Ca as a terrestrial run off proxy in the same region to better understand the impacts of oscillating precipitation in the Eastern Tropical Pacific.
Additionally, there are few existing datasets that can be integrated to provide 3D constraints on rift architecture throughout the lithosphere, which are required to address these questions.
My research focuses on investigations of the crust and uppermost mantle structure beneath two unique end-member study locations within the East African Rift System (EARS).
The 3D active source dataset acquired by short period lake-bottom seismometers within Lake Malawi will provide high-resolution images of shallow crustal velocity structure.
