First vertical derivative of the magnetic field, Aeromagnetic Survey of the Nisling River Area, NTS 115 G/16 and 115 H/13, Yukon

First vertical derivative of the magnetic field, Aeromagnetic Survey of the Nisling River Area, NTS 115 G/16 and 115 H/13, Yukon This high sensitivity aeromagnetic survey was carried out by Goldak Airborne Surveys (Goldak) on behalf of the Geological Survey of Canada (GSC) between January 25th and March 26th, 2011. Aircraft equipment operated included three cesium vapour magnetometers, a GPS real-time and post-corrected differential positioning system, a flight path recovery camera, VHS titling and recording system, as well as radar and barometric altimeters. All data were recorded digitally in GEDAS binary file format. Reference ground equipment included two GEM Systems GSM-19W Overhauser magnetometers and a Novatel 12 channel GPS base station which was set up at the base of operations for differential post-flight corrections. Eighty two flights (including test and calibration sorties) were required to complete the survey block. A total of 37,999 line kilometres of high resolution magnetic data were collected, processed and plotted. The traverse lines were flown at a spacing of 400 metres with control lines flown at a separation of 2400 metres. Nominal terrain clearance was specified at 100 metres above ground. 2022-03-29 Government of Yukon geology@gov.yk.ca Form DescriptorsNature and EnvironmentScience and TechnologyYukon Geological SurveyAirborne geophysicsGovernment information Original metadata (https://open.yukon.ca)HTML https://open.yukon.ca/data/datasets/first-vertical-derivative-magnetic-field-aeromagnetic-survey-nisling-river-area-nts-29 Reportother https://data.geology.gov.yk.ca/reference/50337 Grid Dataother https://data.geology.gov.yk.ca/reference/50337 Mapother https://data.geology.gov.yk.ca/reference/50337 Line Dataother https://data.geology.gov.yk.ca/reference/50337
