<p>I assume the field strength is between 0.6 gauss and 0.65 gauss, but I cannot tell between which ios-flux lines (if that is a legitimate term) McMurdo Station is located.  Are there precise measurements of the magnetic field strength at that location, within 0.01 gauss?</p>

At co-ord 77 deg 51' S, 166 deg 40' E, [Mc Murdo Station](https://en.wikipedia.org/wiki/McMurdo_Station) is just off the map. From my interpolation of where it lies, the magnetic field strength is close to 64 000 nT.
