6 <meta name="description" content="Welcome to the Estimation of the
7 Circulation and Climate of the Ocean (ECCO) project homepage. ECCO is a consortium
8 involving the Massachusetts Institute of Technology (MIT), the Jet Propulsion
9 Laboratory (JPL/NASA), the Scripps Institution of Oceanography (SIO/SDSC) and the Institut
10 fuer Meereskunde at the University of Hamburg (IfM). It is funded by the National
11 Oceanographic Partnership Program (NOPP). The long term goal of ECCO is to provide
12 a high resolution coupled ocean/sea-ice/biochemical (and ultimately, consistent
13 atmospheric) state estimate to a wide community." />

94 <p><span class="headergray">February 2014: Announcing a new-generation, global, bi-decadal state estimate: ECCO version 4</span></p>
95 <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.
96 <br>
97 <br>
98 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

102 <br>
103 <br>
104 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.
105 <br>
106 <br>
107 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:

124 <p> The MIT/AER ECCO-GODAE project issued a new solution of its recent version 3 system. 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).

132 <p> As part of his Ph.D. thesis, <a href="http://www-pord.ucsd.edu/~mmazloff/" target="_blank">Matt Mazloff</a> has produced an eddy-permitting state estimate at 1/6 degree horizontal resolution of the Southern Ocean, covering the Argo-rich period 2005/06. The adjoint-based solution is dynamically consistent and enables closed budget calculations of various quantities. Matt's thesis was featured in the <a href="http://www.sdsc.edu/us/newsletter/common/newsletter.php?%20issue=2006-02&corner=fstory">SDSC Thread Newsletter</a>, and more recently in WHOI's Oceanus magazine (<a href="http://www.whoi.edu/oceanus/viewArticle.do?id=49240&archives=true" target="_blank">Corralling the Wild and Wooly Southern Ocean</a>).</p>

150 (ECCO-GODAE, ECCO2, GECCO, ...).
151 It is hoped that readers will get a clear understanding

154 among ECCO's various ocean state estimation products
155 those which best suit their needs.

159 <p class="headergray">30 March 2007: Ocean model captures diversity of marine microbes</p>
160 <p> Scientists at MIT have developed a new marine ecosystem model that allows its populations of
161 phytoplankton to realistically evolve, reflecting the diversity in populations in the natural world. This
162 should lead to a better understanding of the coupling between ocean and atmospheric chemistry.
163 The model makes use of ECCO's ocean state estimate to capture the physical environment in
164 which the ecosystem evolves. The study &quot;Emergent Biogeography of Microbial Communities in a
165 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>. It is part of the <a href="http://www.moore.org/newsitem.aspx?id=2064" target="_blank">MIT Darwin Project</a> and funded by the Gordon and Betty Moore Foundation.<br />

176 SDSC's DataCentral specialist Roman Olschanowsky
177 and MIT's Constantinos Evangelinos successfully
178 implemented DODS/OPeNDAP on top of SRB.
179 The SRB system allows fast and easy data access

192 of salinity (conductivity), temperature, and depth (CTD) taken by elephant
193 seals which carried bio-logging and telemetry devices
194 was added to the ECCO state estimation system as new

199 to go under the sea-ice which covers large parts of the Southern
