Multi-Sensor Core Logger Laboratory

Learn about the multi-sensor core logger (MSCL) at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California.

PCMSC scientists collect sediment cores from coastal, fluvial, estuarine, lacustrine, and marine environments. The first stop for many of these cores is the Geotek MSCL. The MSCL automatically measures P-wave velocity, magnetic susceptibility, electrical resistivity, and gamma density at intervals from 1 millimeter to 1 centimeter along cores up to 1.5 meters long. The device can also automatically line-scan photograph cores that have been split, at a resolution of 10 microns.
