[MITgcm-support] Equation of state for extreme paleo scenarios

[Martin Losch]

Hi Sonya,

maybe it makes sense to implement an EOS like this one: <http://water.usgs.gov/nrp/proj.bib/Publications/2011/naftz_millero_etal_2011.pdf>
?
there are also extensions to the “standard" TEOS-10:
<http://www.sciencedirect.com/science/article/pii/S0011916409009886>

I see the only problem with the implemented EOSes in the accuracy going down very much as you leave the “Neptunian” range (of present day ocean salinities); Feistel reports errors of 1% for absolute S = 70g/kg. I wouldn’t expect any numerical issues.

I'm wondering what equation of state is most appropriate for simulations of Med outflow with 130 PSU salinity (those are the numbers the paleo people are telling me). Right now I'm using MDJWF, and so far nothing crashed, but I'm not sure if it is correct in this range...
