Descend via the nearest pole
Is this only applicable to contingencies in the Northern Hemisphere (South ascend North descend - SAND) Should we descend towards the South pole in the Southern Hemisphere?

Gets higher towards the equator and lower towards the poles -> climb if turning towards the equator, descend if turning towards the poles.

I'm guessing... garbled acceleration errors on a direct reading compass? see PPRuNe

No, it does not indeed but we are all very much aware that this -like many others- is just a mnemonic rule of thumb which could, by the way, become unusable tomorrow morning if procedures change even in the Northern Hemisphere. No need to get excited, people still look at their contingencies for different airspaces before thinking about acronyms.
