The Seward Peninsula airborne electromagnetic survey covers parts of the Teller, Bendeleben, Nome, and Solomon 1:250,000-scale U.S. Geological Survey (USGS) quadrangles on the Seward Peninsula north of Nome, Alaska. Time-domain electromagnetic data were collected with the SkyTEM 306HP system, which was towed by a helicopter, from September 8 to October 3, 2023, and from June 5 to July 18, 2024. A total of 4,330-line kilometers (km) were collected covering 4,817 km2. The survey was flown with semi-parallel lines spaced approximately 1 km apart and oriented perpendicular to regional geologic strike. Electromagnetic data were used to create resistivity models.
