Why does the main picture caption say "Chicxulub Gravity Anomaly in the WDMAM" not "Magnetic Anomaly"? — Preceding unsigned comment added by 220.127.116.11 (talk) 13:47, 25 April 2013 (UTC)
My guess is that it's there to illustrate the Chicxulub crater and not a magnetic anomaly map, but it is extremely misleading indeed. Could someone please either reword the caption to explain to the reader why we have a fragment of a gravity anomaly map illustrating an article about a magnetic anomaly map or simply remove the illustration? — Kpalion(talk) 21:36, 25 April 2013 (UTC)
That's the magnetic model that WDMAM is using, it's based on the NGDC one, but isn't necessarily in public domain as far as I can make out - I can't find any WDMAM images on the NGDC geomagnetics page and the images from EMAG3 are copyrighted unfortunately.
