from Stuart Wyithe (who Knows About These Things) I think its just density as you say, mostly near the surface. Geologists use accelerometers to find cave size holes under the ground from anomalies of this sort. For clarification, the units are micrometers per second squared, so that the biggest change is around 1 part in 10000 in acceleration, or about 10 grams. So one is still better off taking a big dump in the morning than flying to a low gravity area! as always, alas..
