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.
