This DVD-ROM (Digital\nVersatile Disc-Read Only Memory) has been produced in accordance with the\nUDF (Universal Disc Format) DVD-ROM Standard (ISO 9660 equivalent) and is\ntherefore capable of being read on any computing platform that has\nappropriate DVD-ROM driver software installed. Access to the data and\ninformation contained on this DVD-ROM was developed using the HyperText\nMarkup Language (HTML) utilized by the World Wide Web (WWW) project.\nDevelopment of the DVD-ROM documentation and user interface in HTML allows\na user to access the information by using a variety of WWW information\nbrowsers (i.e. NCSA Mosaic, Netscape) to facilitate browsing and locating\ninformation and data. To access the information contained on this disk\nwith a WWW client browser, open the file 'index.htm' at the top level\ndirectory of this DVD-ROM with your selected browser. The HTML documentation is written utilizing some HTML 4.0 enhancements. The disk\nshould be viewable by all WWW browsers but may not properly format on some\nolder WWW browsers. Also, some links to USGS collaborators and other\nagencies are available on this DVD-ROM. These links are only accessible if\naccess to the Internet is available during browsing of the DVD-ROM. The\narchived Chirp subbottom data are in standard Society of Exploration\nGeologists (SEG) SEG-Y format (Barry and others, 1975) and may be\ndownloaded for processing with software such as Seismic Unix or SIOSEIS.\nThe subbottom data were recorded on the ISIS data acquisition system in\nQMIPS format. Chirp subbottom channel extracted from raw QMIPS format\nsonar files and converted to 16-bit Int. SEG-Y format using the program\nQMIPSTOSEGY. Even though the data are in SEG-Y format, it is not the\nconventional time series data (e.g. voltages or pressures), but rather\ninstantaneous amplitude or envelope detected and therefore all of the\namplitudes are positive (though not simply rectified). DOS and Microsoft\nWindows compatible software for plotting SEG-Y files (PLOTSEIS) and\nviewing SEG-Y headers (DUMPSEGY) is located in the PLOTSEIS directory.\nProcessed chirp profiles (GIF images) may be viewed on this DVD-ROM with\nyour WWW browser.\nFor more information on the seismic surveys see https://cmgds.marine.usgs.gov/fan_info.php?fan=1996-004-FA\nThese data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://cmgds.marine.usgs.gov/data/1996_004_FA_c/", "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.c09aec35-6385-418d-a0be-197c707c9c0a.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_c09aec35-6385-418d-a0be-197c707c9c0a", "keyword": ["Atlantic Ocean", "Chirp", "Datasonics SIS-1000", "Eastern Regional Center", "Long Island inner shelf", "New Jersey", "New York", "New York Bight", "SEG-Y", "U.S. Geological Survey", "USGS", "USGS:c09aec35-6385-418d-a0be-197c707c9c0a", "Woods Hole Field Center (WHFC)", "distributions", "field activity 96004", "geoscientificInformation", "high resolution", "marine geophysics", "oceans", "seismic reflection", "seismic reflection methods", "seismic reflection profiling", "sub-bottom profiling", "substrate"], "modified": "2024-03-18T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-73.84, 40.35, -73.03, 40.67", "theme": ["geospatial"], "title": "Archive of Datasonics SIS-1000 Chirp Subbottom Data Collected During USGS Cruise SEAX 96004 New York Bight, 1 May - 9 June, 1996"}
