The data were collected on September 3 and September 5, 2017, as part of a larger Arctic coastal erosion investigation study by the U.S. Geological Survey (USGS). The data contain latitude, longitude and CH4 (ppm), and are presented as tab-delimited text files that have been zipped into one file.\nIn addition, we have included one file of comparative data from Barrow, Alaska that were collected by the National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Division from 1986-2017 as a courtesy to users. The three datasets together accompany Oberle, F.K.J., Gibbs, A.E., Richmond, B.M., Erikson, L.H., Waldrop, M.P., and Swarzenski, P.W., 2019, Towards determining spatial methane distribution on Arctic permafrost bluffs with an unmanned aerial system: SN Applied Sciences, https://doi.org/10.1007/s42452-019-0242-9.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.1594/PANGAEA.898636", "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.7040f233-f889-4451-914f-c2acb0493fa6.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_7040f233-f889-4451-914f-c2acb0493fa6", "keyword": ["Coastal and Marine Hazards and Resources Program", "Barrow", "CH4", "geospatial datasets", "Unamanned Aerial System Survey", "global climate change", "Assessments", "methanogens", "Methane", "U.S. Geological Survey", "USGS:7040f233-f889-4451-914f-c2acb0493fa6", "USGS", "CMHRP", "remote sensing", "field observation", "environment", "State of Alaska", "cold seep", "permafrost", "Drone", "Barter Island", "Methane Laser Sensor", "Pacific Coastal and Marine Science Center", "geoscientificInformation", "sediment geochemistry", "effects of climate change", "PCMSC", "Arctic", "light stable isotopic analysis"], "modified": "2020-10-19T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-156.611400, 70.132331, -143.647148, 71.323000", "theme": ["geospatial"], "title": "UAV-based methane data from Barter Island, Northern Alaska, September 2017"}
