Centers and Labs
Comparative Sedimentology Laboratory & Center for Carbonate Research
The mission of the Comparative Sedimentology Laboratory at the UM Rosenstiel School is to conduct research in facies, sequence stratigraphy, petrophysics, and geochemistry in modern and ancient carbonate systems to enhance prediction of carbonate reservoir attributes on exploration and production scale. The Comparative Sedimentology Laboratory conducts integrated research in sedimentology, stratigraphy, geochemistry, and geophysics basic research to better understand the processes controlling carbonate systems and reservoirs. Research in the lab has three main themes:
• Carbonate Systems and Reservoir Characterization
• Geophysics and Petrophysics of Carbonates
• Geochemistry and Diagenesis of Carbonates

Core Imaging Laboratory
The Core Imaging Laboratory, known internally as Club Mud, houses an Avaatech X-Ray Fluorescence Core Scanner and a GEOTEK Multi-Sensor Core Logger, instruments that together provide rapid non-destructive measurements of geochemical and geophysical properties in sediment or rock cores. X-ray fluorescence spectrometry is an active sensing method that uses X-ray emissions to sense elements of different atomic number. XRF core scanners are designed to make such measurements on split core surfaces. The Club Mud XRF scanner provides concentration data on a broad suite of elements ranging from Al through U, with detection limits for lithologically important elements that come close to what can achieved through traditional methods. Our instrument was the first Avaatech XRF scanner installed in North America. XRF core scanners are ideally suited for high-resolution paleoclimatic and paleoceanographic studies of the type undertaken at the Rosenstiel School because of the ability to generate elemental data rapidly without physical sampling and because the wide range of elements that can be detected provides a powerful means of constraining sediment composition and conditions of deposition.
For geophysical measurements, a Geotek Multi-Sensor Core Logger (MSCL) is available that enables a suite of analyses to be obtained rapidly, accurately and automatically on sediment or rock cores. The range of parameters that can be measured includes P-wave velocity, gamma density, magnetic susceptibility, and electrical resistivity. A GEOSCAN digital line scan camera system provides precise depth-registered images that can be correlated with other data sets or used when describing cores.

Neptune Isotope Laboratory
The Neptune Isotope Laboratory at the UM Rosenstiel School provides a clean-room enclosure with several class-100 vertical and horizontal laminar flow hoods, two high-purity water systems, sub-boiling acid distillation units and two, class-100 trace metal workstations for low-blank sample processing and wet chemistry. The lab is also equipped with a ThermoFisher Neptune Plus, high performance Multi-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) and a New Wave Excimer 193 nm Laser Ablation (LA) system.
The facility is capable of making the following routine measurements, and continues adding new isotope systematics:
• High-precision analysis of Li, B, Ca, Mg and, Fe isotopes.
• High precision analysis of Hf and the Rare Earth Element (REE) isotopes.
• High-precision analysis of Sr isotopes using wet chemistry and LA-MC-ICP-MS.
• Bulk elemental analysis of the REE, Sc and Y using MC-ICP-MS.
• Closed-system U-Th geochronology of carbonate rocks, including corals and speleothems.

Seismology and Geodesy Laboratory
The Seismology and Geodesy Lab (SGL) at the UM Rosenstiel School is using seismological and space-geodetic methods to conduct research on active processes under and above the Earth's surface. The techniques used include seismic tomography and earthquake relocations, Interferometric Synthetic Aperture Radar (InSAR) and Global Positioning Systems. The research topics include active volcanoes, active tectonics, changes of the global ice masses, hydrology and vegetation. The SGL state-of-the-art research techniques include: Seismic tomography and earthquake relocation, Synthetic Aperture Radar (SAR), Interferometric Synthetic Aperture Radar (InSAR), Global Positioning System (GPS), and Ground-based Light Detection and Ranging (LiDAR).

Stable Isotope Laboratory
Research in the Stable Isotope Laboratory at the UM Rosenstiel School centers on the application of stable isotopic tracers to geologic, biologic, and environmental problems. Projects range from paleo-oceanographic studies of climate change in the Holocene to modern-day analyses of pollution impacts on corals and coastal resources of Florida. Faculty, staff, and students are conducting research on a global scale including extensive research in the Florida Everglades and Florida Bay, The Bahamas, The Dominican Republic, Africa, Saudi Arabia, Kuwait, Australia, and Europe.
