The free-air gravity anomaly grid was derived from raw gravity data acquired with a Bell BGM-3 gravimeter and converted to mGal values using the meter constant. A 10 minute cosine taper was then applied to the 1 second values and output at 10 second intervals. Eötvös corrections for ship speed, cour...

The free-air gravity anomaly grid was derived from raw gravity data acquired with a Bell BGM-3 gravimeter and converted to mGal values using the meter constant.

The values were adjusted to the gravity tie value at Reykjavik, Iceland, and the International Gravity Formula correction using WGS84 ellipsoid parameters was removed to yield the free-air anomaly. The gravity survey was conducted at the southern end of the Reykjanes Ridge, a segment of the Mid-Atlantic Ridge, in 2013 during Langseth cruise MGL1309 (investigators Fernando Martinez and Richard Hey).
