The lede to the article says that the Sumatera-Java Arc is also known as the Paris Basin, but the link is to an article about a feature in France. 202.155.85.18 (talk) 09:37, 25 April 2013 (UTC)[reply]
It's the product of misunderstanding a clunky sentence in the citation and I've corrected it. Rsloch (talk) 10:05, 25 April 2013 (UTC)[reply]
Why does the main picture caption say "Chicxulub Gravity Anomaly in the WDMAM" not "Magnetic Anomaly"? — Preceding unsigned comment added by 140.90.100.199 (talk) 13:47, 25 April 2013 (UTC)[reply]
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)[reply]
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.
