USGS scientists collect core samples from estuaries, lakes, coasts, and marine environments to study a range of physical and chemical properties preserved in sediments over time. They process and analyze these core samples in the Pacific Coastal and Marine Science Center’s Core Labs.
We store sediment cores, along with other sediment, plant, and microfossil 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.
