Description:
Abstract:
In June 2010, the U.S. Geological Survey conducted airborne electromagnetic and magnetic surveys of the Yukon Flats and Fort Wainwright study areas in central Alaska. These data were collected to estimate the three-dimensional distribution of permafrost at the time of the survey. These data were also collected to evaluate the effectiveness of these geophysical methods at mapping permafrost geometry and to better define the physical properties of the subsurface in discontinuous permafrost areas.
Purpose:
In June 2010, the U.S. Geological Survey conducted an airborne electromagnetic survey of the area near Fort Yukon commonly referred to as Yukon Flats, in central Alaska. Lines were flown in a block configuration at 350-m line spacing near the town of Fort Yukon. Additional flight lines extend from the block in zig-zagging transects to the southwest (block 2, 400.6 total line km) and northeast (block 3, 487.5 total line km). The AEM measurements were used to develop inverse models of the electrical resistivity structure along flight lines. These models, in conjuction with other remote sensing and ground-based data, provide a foundation for interpreting the distribution of permafrost.
