UNDERGRADUATE PROJECT AVAILABLE (For Summer 2020):

We have a data analysis project available for an undergrad interested in doing research in local water quality in Mississippi Sound. We have collected about a year’s worth a data on the water’s optical properties (including absorbance and fluorescence) that will tell us something about the dissolved organic matter in the water. Over the past year, the Bonnet Carre Spillway had been open, diverting large amounts of water from the Mississippi River into Mississippi Sound and several other major properties of the water changed. This project will involve MATLAB data processing and interpretations as to the changing quality of the water relevant for biological systems. This project can be done remotely. Contact me about how to apply for funding.

Description of Laboratory:

We maintain a wet chemical laboratory for processing seawater and marine sediments for various analyses. Our specialty is in thorium and uranium isotopes. A class 100 laminar flow hood and a Smart2Pure, high-purity water system, are used for contamination-prone metals. We use an on-site facility Element 2 XR: Inductively-Coupled Plasma Mass Spectrometer (ICP-MS). We also have the capability for total sediment dissolutions, carbon system parameters, and sedimentary biogenic silica.
