Radiocarbon dating calibration involves
For a greater understanding of the effects of sea level change on a stratigraphic column, a 3D seismic volume was just acquired on the New Jersey continental shelf, aboard R/V Langseth in the summer of 2015.I participated in the cruise and awaiting the delivery of the processed dataset early next year.Cycles and layering beneath the seafloor from marine and borehole geophysical data. In my first chapter, I examine the effect of short-term tidal cycles in the ocean.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.
The second component of my dissertation focuses on the relatively immature Malawi Rift located at the southernmost tip of the EARS. GULEED ALI Hemming, Christie-Blick, Broecker My dissertation work is focused on constraining a Last Glacial Maximum and deglacial record of hydroclimate change from the Mono Basin, California.The emphasis of my work is on sedimentary and stratigraphic observations that I use to interpret lake level fluctuations--a proxy for changes in the basin's precipitation minus evaporation balance.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.Together these diverse datasets will yield novel constraints on the state of the Malawi Rift and the role of segmentation and magmatism in an immature continental rift setting.
