A total of 52 surficial sediment samples were collected within a 1-km x 1-km area around Crocker Reef in the Florida Keys, USA, between 2013 and 2014.  Samples 1-35 were collected in July 2013 and samples 36-52 were collected in July 2014. The samples were processed using conventional, published techniques (see process step section) to yield grain size and mineralogical data. The dataset, CRKR2013-2014_SEDIMENT_Images.zip contains photomicrograph images that correspond to each sediment sample. These images also include additional, survey-specific EXchangable Image File format (EXIF) header information.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7V40SBR", "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.41542322-3fc2-417d-a77b-583aa1f78703.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_41542322-3fc2-417d-a77b-583aa1f78703", "keyword": ["Crocker Reef", "DOI/USGS/CMG > COASTAL AND MARINE GEOLOGY, U.S. GEOLOGICAL SURVEY, U.S. DEPARTMENT OF INTERIOR", "EARTH REMOTE SENSING INSTRUMENTS > PASSIVE REMOTE SENSING > PHOTON/OPTICAL DETECTORS > CAMERAS > CAMERAS", "Florida", "Florida Keys", "OCEAN > COASTAL PROCESSES > CORAL REEFS", "OCEAN > MARINE SEDIMENTS > SEDIMENT COMPOSITION", "USGS:41542322-3fc2-417d-a77b-583aa1f78703", "aquatic biology", "coral reef", "geoscientificInformation", "marine geology", "oceans", "remote sensing", "seafloor", "sediment images", "sediment samples"], "modified": "2020-10-13T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-80.5359189100, 24.9033566400, -80.5209581100, 24.9167055000", "theme": ["geospatial"], "title": "Photomicrograph Images of Sediment Samples Collected at Crocker Reef, Florida, 2013-2014"}
