NOAA's Pacific Marine Environmental Lab estimated the aragonite and calcite saturation state, excess alkalinity and carbonate dissolution in the water column. This plot displays the location of aragonite and calcite saturation state and allowed them to determine the amount of calcium carbonate added by particle dissolution in the Pacific Ocean, north of 40°S, to be 157 Pg C as calcium carbonate. This amounts to an average dissolution rate of ~0.31 Pg C per year, which is approximately 74% of the export production of calcium carbonate estimated for the Pacific Ocean.

An interesting "collapse structure" close to the Elysium Mons volcano complex on Mars. It may be possible that this feature is linked to both volcanic activity and/or melting of sub-surface ice to generate a "void" into which the surface rocks have collapsed but is difficult to prove conclusively. Ring faults are well defined and a localised ejecta margin. An explosive volcanic event followed by collapse is also a possibility given the proximity to the Elysium complex.

The primary data for this model originated from a 3D seismic interpretation along with data from five wells within the area. Surfer was used to interpolate the geological layers and calculate the depths of every layer. Strater cross sections display well logs, lithology, and surfaces of the laters between the wells. Voxler was used for the final visualization. Only the top and bottom surfaces are visible for improved visualization. Image courtesy of http://www.strike-dip.comLearn More
