The objective of this\nwork is to relate optical and acoustic properties of suspended particles as a function of particle\nsize, concentration, and vertical distribution near the sea floor. In order to accomplish this\ntask, a specially modified tripod allows vertical profiling near the sea floor by moving\ninstruments up and down within 2 meters of the sea floor. The profiling arm was designed and built\nby a team of scientists, engineers and technicians from the USGS Woods Hole Coastal and Marine\nScience Center (WHCMSC). To accommodate communications and provide power  required for arm movement\nand control, the tripod was connected via underwater cable to the Martha's Vineyard Coastal\nObservatory (MVCO), operated by Woods Hole Oceanographic Institution (WHOI). In addition to the\ninstruments on the profiling arm, other instruments were mounted elsewhere on the static portion of\nthe tripod and nearby on a nearby seafloor platform. The tripod (USGS Mooring 910) and seafloor\nplatform (911)  were deployed on September 17, 2011 at the MVCO 12-m deep underwater node which is\nabout 2 kilometers (km) south of Martha's Vineyard, Massachusetts. Divers assisted in the\ndeployment and cleaned the acoustic and optical instrument faces on the tripod approximately once a\nweek until recovery on 23 October, 2011.\nFor more information on the field operations associated with data collection:\nhttp://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=11048\nhttp://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=11051\nhttp://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=11052\nhttp://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=11053\nhttp://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=11054", "distribution": [{"@type": "dcat:Distribution", "accessURL": "http://stellwagen.er.usgs.gov/mvco2011.html", "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.08a1765e-daa2-49b8-9b69-7ed13924d7b0.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_08a1765e-daa2-49b8-9b69-7ed13924d7b0", "keyword": ["2011-048-FA", "2011-051-FA", "2011-052-FA", "2011-053-FA", "2011-054-FA", "Acoustic Backscatter", "Acoustic Doppler Current Profiler (ADCP)", "Atlantic Ocean", "BBL", "Beam attenuation", "Benthic Boundary Layer", "CMGP", "Coastal and Marine Geology Program", "Current", "Light transmission", "MVCO", "Martha's Vineyard", "Martha's Vineyard Coastal Observatory", "Massachusetts", "New England inner shelf", "North America", "Oceanographic observations", "Oxygen", "Pressure", "Salinity", "Sediment-trapping rate", "Suspended Sediment concentration", "Temperature", "Turbidity", "U.S. Geological Survey", "USGS", "USGS:08a1765e-daa2-49b8-9b69-7ed13924d7b0", "United States", "WHCMSC", "Waves", "Woods Hole Coastal and Marine Science Center", "climatologyMeteorologyAtmosphere", "geoscientificInformation", "marine geophysics", "moving arm", "navigational data", "netCDF", "oceans", "profiling arm"], "modified": "2022-07-07T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-70.55663, +41.336365, -70.55656, +41.336480", "theme": ["geospatial"], "title": "Static Oceanographic Observations made by the USGS Coastal and Marine Geology Program at Martha's Vineyard Coastal Observatory, September and October 2011"}
