Straps on mag data

Hi,

I am facing a strange phenomenon with the mag data i am acquiring. Data is acquired in parallel lines and the background noise is different following the acquisition direction. the difference is about 10nT and it is regular all over the site following North south or East-West directions. Sensors were tilted 45 degrees but it still there.
Is there any explanation for behavior?

  • I have encountered same problem before...What kind of magnetometer did you used...if it was GEM, then check your sensor orientation...that should fix the stripy data problem
