Stations sampled were located within or adjacent to an area defined for strategic sediment placement. These stations were more specifically located either near instrumented stations where time-series data were collected, on/near a mound of placed sediment, or in a channel adjacent to an instrumented station. Time-series data are provided on the home page for this data release. Sediment samples were collected by ship-side push core sampling or subsampling a Gomex box corer with push cores. Push cores, which ranged in total length from 6 to 16 centimeters (cm), were sectioned by depth. The uppermost six sections from each core were 1 cm thick, and the following sections were 2 cm thick. Samples were analyzed for sediment properties including bulk density, particle size distribution, and percent carbon.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066-P14D723N", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.906157c2-b9bb-4bf4-990c-c5a7ea8c8f87.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_906157c2-b9bb-4bf4-990c-c5a7ea8c8f87", "keyword": ["CMHRP", "Coastal and Marine Hazards and Resources Program", "Eden Landing Ecological Reserve", "PCMSC", "Pacific Coastal and Marine Science Center", "San Francisco Bay", "Sediment", "South San Francisco Bay", "State of California", "Substrate", "U.S. Geological Survey", "USGS", "USGS:906157c2-b9bb-4bf4-990c-c5a7ea8c8f87", "bulk density", "carbon", "grab sampling", "grain-size analysis", "oceans", "push coring", "sea-floor characteristics", "sediment transport", "unconsolidated deposits"], "modified": "2025-08-20T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.21167, 37.57107, -122.14669, 37.60643", "theme": ["geospatial"], "title": "Properties of sediment collected throughout the strategic placement of dredge material in south San Francisco Bay, California, 2023-2025"}
