Since 2002, the Woods Hole Coastal and Marine Science Center’s Samples Repository supports research by providing secure storage for geological, biological, and geochemical samples; maintaining organization and an active inventory of these sample collections; and providing access to these collections for study and reuse. This collections inventory has been compiled, organized, and released as a searchable database to provide researchers and the general public with means to discover and request scientific ...

This data release provides 210Pb and 137Cs measurements in sediments of a core obtained off San Francisquito Creek in South San Francisco Bay.

This data release provides census counts of diatoms in sediments of a core obtained off San Francisquito Creek in South San Francisco Bay.

This data release provides census counts of benthic foraminifera in sediments of a core obtained off San Francisquito Creek in South San Francisco Bay.

This data release provides the measurement of anthropogenic metals and other elements in sediments of a core obtained off San Francisquito Creek in South San Francisco Bay.

This data release provides census counts of palynomorphs in sediments of a core obtained off San Francisquito Creek in South San Francisco Bay.

This data release provides radiocarbon measurements from a core obtained off San Francisquito Creek in South San Francisco Bay.

This data release contains information on gravity cores that were collected by the U.S. Geological Survey in the area of San Pablo Bay and Carquinez Strait, California in 1990, 1991, and 2000. Ten (10) pdf files describe gravity cores that were split, photographed, and imaged by X-rays, and another pdf file contains a core-log legend. In addition, a shapefile provides sample collection data. Seventy-two gravity cores were collected by the U.S. Geological Survey in 1990, 1991, and 2000 from San Pablo Bay and ...

Geochemical analysis of sediment core pore fluids collected from seep fields on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019. Samples were collected to deconvolve the different processes impacting the fluid chemistry, including hydrate dissociation and clay mineral dehydration during the smectite-illite transformation that releases inter-layer water.

This data release contains porewater oxygen microprofiling data from abyssal sediment cores collected from the Samoa Basin in the South Pacific Ocean within the American Samoa Exclusive Economic Zone. Sediment cores were collected from 35 locations using a box core that was subsampled with push cores. Push cores were immediately transferred to a cold laboratory van, and oxygen was measured using Unisense microsensors inserted through pre-drilled holes in the core liner, spaced at 1 centimeter intervals. ...

Percentage of sand content provided in 10 cm intervals down the length of 186 sediment cores collected in San Francisco Bay, California in 1990-91, 2000, 2006, and 2016. Sediment data were obtained from a combination of gravity, box, and push cores ranging in length from 14 to 360 cm. Sand content percentages were obtained from a compilation of visual analyses, descriptive and graphical core logs, and grain size measurements. For the purposes of modeling variability in sand content with depth beneath the ...

Sediment analysis of cores collected in San Francisco Bay, San Pablo Bay, and the Carquinez Strait and Suisun Bay, California from 1990 to 2016 for percent sand. Handwritten core logs, x-radiographs, and the cores themselves, were examined for the presence of sand.

Ferromanganese nodules and other ferromanganese coated rocks were collected using a box core from the Samoa Basin, during USGS field activity 2026-604-FA. Ferromanganese nodules and ferromanganese coated rocks were collected by box core and total mass was determined using a digital crane scale calibrated with National Institute of Standards and Technology certified calibration weights.

Ferromanganese nodules and other ferromanganese coated rocks were collected using a box core from the Samoa Basin, during USGS field activity 2026-604-FA. These mineral samples were described and subsampled for geochemical analysis at the USGS Pacific Coastal and Marine Science Center. Geochemical analyses were completed by an outside commercial laboratory, and the results were provided to the USGS. Geochemical data, sample type and size range, as well as location information (latitude, longitude, depth) ...
