Paleoceanographic Proxy Calibration
Paleoceanographic Proxy Calibration
A sediment trap time series in the northern Gulf of Mexico is used to better assess the control of environmental variables (e.g., temperature and salinity) on the flux of both microfossils and molecular fossils to the sediments.

Environmental controls on the geochemistry of Globorotalia truncatulinoides in the Gulf of Mexico: Implications for paleoceanographic reconstructions
My research primarily focuses on a climate history calibration study in the Gulf of Mexico. The goal is to provide a better understanding of current paleoenvironmental proxies, such as planktic foraminifera. Using a sediment trap mooring to collect foraminifera, we also analyze corresponding temperature and salinity data that is used for our modern calibration. The modern calibration and geochemistry can then be applied to records from deep-sea sediments collected over longer time scales. My favorite foraminifera is Globorotalia truncatulinoides!
I have also been lucky enough to be a part of various interdisciplinary field work studies in Mobile Bay, Seahorse Key, The Florida Keys, Dry Tortugas National Park and cruises on multiple large research vessels across the Gulf of Mexico.

A sediment trap time series in the northern Gulf of Mexico is used to better assess the control of environmental variables (e.g., temperature and salinity) on the flux of both microfossils and molecular fossils to the sediments. The information gained from sediment trap studies is used to develop better proxy-based estimates of past oceanographic conditions from analyses of microfossils and...
Climate and Environmental Change in the Gulf of Mexico and Caribbean
This project documents paleoceanographic, climatic, and environmental changes in the Gulf of Mexico and adjacent land areas over the last 10,000 years. The paleoenvironmental data is used to determine rates of change in the past, and to better understand both the natural and anthropogenic factors that contribute to climate variability on inter-annual to millennial timescales.
