Core Preparation and Analysis Laboratory and Sample Repositories

Learn about the sediment core lab and refrigerated sample repositories at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California.

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 shelving for efficient storage and easy access to all cores. All samples are cataloged and cross-referenced to their field activity ID, which provides the metadata about the samples.

Four scientists stand around a table in a lab with gray sediment core samples on the table, and they are examining the sediment.
(Left to right) Danny Brothers (USGS Pacific Coastal and Marine Science Center [PCMSC]), Peter Haeussler (USGS Alaska Science Center), Maureen Walton (PCMSC), and Jamie Conrad (PCMSC) select seafloor sediment samples from cores collected along the Queen Charlotte-Fairweather fault. They are working in the Geological Survey of Canada (GSC) laboratories in British Columbia.
