+           <p><span class="headergray">February 2014: Announcing a new-generation, global, bi-decadal state estimate: ECCO version 4</span></p>
+           <p>Following the ECCO meeting in January at MIT, the JPL/MIT/AER ECCO-Production team is happy to announce the release of a new-generation, global, bi-decadal state estimate (ECCO-Production, release 1). The product covers the period 1992 to 2011.
+ <br>
+ <br>
+ Several aspects of this new product have been highlighted already during the ECCO meeting. To re-iterate, some of the features include a fully global grid (LLC90) with the inclusion of the Arctic Ocean, telescoping from 1 to 1/3 deg. in the tropics, a doubling in vertical resolution (from 23 to 50 levels), forcing with the ERA-Interim atmospheric reanalysis, and improved treatment of data sets in terms of resolved vs. unresolved scales. The state estimate is being made available on its native grid on the DODS/OPeNDAP server

+ <br>
+ <br>
+ The sub-directory ancillary_data/ has some extra information, including our standard analysis (standardAnalysis.pdf) that documents model-data misfits and physical variables of general interest. A copy of the matlab codes used to generate the standard analysis is also provided (gcmfaces_MITprof_r1.tar). As with releases of previous estimates, we think that many aspects of this release are mature (and improvements from previous versions), but with further  improvements of some aspects to be expected in subsequent releases.

+ Gael Forget has played a leading role in developing ECCO v4 and producing the released estimate. [UPDATE 2015:] A more detailed paper describing the design of ECCO v4, and the solution is available at:

The new solution uses atmospheric state fields as control variables in conjunction with an adjoint of the Large and Yeager surface boundary layer scheme, as well as a dynamic/thermodynamical sea-ice model. The solution has been update through the end of 2007 (calculations through end of 2008 are under way).

                <p>                Scientists at MIT have developed a new  marine ecosystem model that allows its populations of
                  phytoplankton to  realistically evolve, reflecting the diversity in populations in the natural  world. This
                  should lead to a better understanding of the coupling between ocean  and atmospheric chemistry.
                  The model makes use of ECCO's ocean state estimate  to capture the physical environment in
                  which the ecosystem evolves. The study  &quot;Emergent Biogeography of Microbial Communities in a
                  Model Ocean&quot;  &nbsp;by  Michael J. Follows, Stephanie Dutkiewicz, Scott Grant, and Sallie W. Chisholm  was published in today's issue of <a href="http://www.sciencemag.org/cgi/content/abstract/315/5820/1843" target="_blank">Science magazine</a>.
