Summary
These data have been temporarily taken down. Please contact Benjamin J Drenth (bdrenth@usgs.gov) for more information. This publication provides digital flight line data for a high-resolution magnetic survey over an area of the west-central Upper Peninsula of Michigan. The survey was flown in 2008 by Aeroquest under contract to Kennecott Eagle Minerals Company using a fixed-wing aircraft with a magnetometer mounted in a tail stinger. The USGS has obtained this 66,074 line km subset of the survey dataset for public release. Data were collected along north-south flight lines spaced 100 meters apart with east-west tie lines flown every 1000 meters. The nominal terrain clearance was 40 meters, although greater terrain clearances were [...]

This publication provides digital flight line data for a high-resolution magnetic survey over an area of the west-central Upper Peninsula of Michigan. The survey was flown in 2008 by Aeroquest under contract to Kennecott Eagle Minerals Company using a fixed-wing aircraft with a magnetometer mounted in a tail stinger. The USGS has obtained this 66,074 line km subset of the survey dataset for public release. Data were collected along north-south flight lines spaced 100 meters apart with east-west tie lines flown every 1000 meters. The nominal terrain clearance was 40 meters, although greater terrain clearances were required in several areas due to safety and aircraft performance considerations. Files that are available in this publication include flight line data for the magnetic survey and a report describing the survey parameters, field operations, quality control and data reduction procedures.
The purpose of this data release is to provide the data to the public. The primary goal of the airborne magnetic survey is to map lateral variations of magnetization that are related to differences in rock type, and to aid surface and subsurface geologic mapping.
