Multi-Sensor Core Logger Laboratory

The MSCL at the USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California 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...

Sediment Lab Suite and Carbon Analysis Lab

At our Science Center, we have a suite of laboratories that we affectionately call the "sed lab." The sed lab really consists of 5 labs, arranged next to each other to allow our lab technicians to easily move back and forth between them while processing sediment samples: Sediment Preparation Lab, Fine Particle Analysis Lab, Settling Tubes Lab, Fume Hood Lab, and Carbon Analysis Lab.

Core Preparation and Analysis Laboratory and Sample Repositories

We process and analyze sediment cores collected from coastal, fluvial, estuarine, lacustrine, and marine environments. We have a Geotek core splitter, shrink wrap system, and a wide assortment of sampling tools and balances for core sample preparation and analysis. We store the cores, along with other sediment samples, in a large, walk-in refrigerated room that features library-style rolling...

Core X-Ray: 3-D CT Core Imaging Laboratory

The Geotek RXCT, a "rotating x-ray computed tomography" system, creates ultra high-resolution imagery of sediment cores. The system resides at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California. It requires the operator to take specialized training and hold X-ray radiation and safety certifications.
