• Project ID:

  76

• Nickname/Abbreviation:

  Koyukuk-Wiseman GP

• Parent Project:

  Geophysics Program

• Status:

  Complete

• Description:

  The Koyukuk geophysical survey is located in interior Alaska in the Koyukuk mining district, about 300 kilometers north of Fairbanks, Alaska. Frequency domain electromagnetic and magnetic data were collected with the SIGHEM-5 system from August to October 1997. A total of 4223.4 line kilometers were collected covering 533 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ("bird") on a 30-m-long line.
