[ecco-support] ECCO dataset(s) for the Southern Ocean

[Patrick Heimbach]

Hi Chris,

I had a summer intern working on a comparison between SOSE 2005-2010 and the latest release 3 of ECCO version 4 (it is work in progress/incomplete/in-limbo/perhaps never to be completed). The comparison was performed for the overlapping period, and focusing on a sector in the Southern Ocean (basically the wider Amundsen and Bellingshausen Sea region). My take-away from it is that it is definitely worth also considering the coarser-reslolution ECCO-v4-r3, which permits a useful extension to 2015 (at least in that sector it shows some merits and limitations of each, at least at a zeroth-order level). There is a presentation available showing some of the outcomes. Also a report, but which I don't have yet and which will be in French. Let me know if you'd like to see the presentation.

The latest ECCO release is available at
ftp://ecco.jpl.nasa.gov/Version4/Release3/

Cheers
-Patrick

I imagine that there are pros and cons for each of the state estimates.  I also accept that there may not be a clear answer to such a general question, but I would be very grateful if you could share a few of your thoughts please.
