Sediment Core Laboratory

Metadata Updated: March 8, 2017

FUNCTION: Provides instrumentation and expertise for physical and geoacoustic characterization of marine sediments.DESCRIPTION: The multisensor core logger measures profiles of compressional wave velocity, wet-bulk density (by gamma-ray attenuation), electrical resistivity, and magnetic susceptibility directly, and acoustic impedance and porosity indirectly. Sediment cores are opened for visual classification, measurement of undrained shear strength via miniature vane and torvane, and subsampling for physical properties tests. Grain-size analyses for coarse sediments are performed by settling tube or standard sieve analysis, and silt and clay particle size distribution is analyzed by the Micromeritics SediGraph. Average grain densities are measured via gas pycnometry using a Quantachrome Penta-Pycnometer.INSTRUMENTATION: A Geotek multisensor core logger, LABCONCO bulk tray freeze dryer, digital macro- and micro-photographic imagery systems, and geotechnical testing instrumentation that includes miniature vane shear and torvane, uni- and triaxial consolidation instruments, geoacoustic Hamilton frame, relative density shaker table, and Quantachrome Penta and Ultra pycnometers. Sediment textural analyses are performed using sieves, pipette analysis, an instrumented settling tube, and a Micromeritics SediGraph, Model 5120.
