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." />

104 <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). The new solution is available via ECCO's <a href="http://www.ecco-group.org/las/v6/dataset?catitem=91" target="_blank">LAS server at MIT</a>.</p>

112 <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>

125 <p>
126 In collaboration with web designer Colleen Boisvert
127 ECCO has launched a new overall project web site.
128 Main purpose of this site is to provide an integrated view
129 of ECCO and it's follow-on projects
130 (ECCO-GODAE, ECCO2, GECCO, ...).
131 It is hoped that readers will get a clear understanding
132 of
133 ECCO's various activities, and will find
134 among ECCO's various ocean state estimation products
135 those which best suit their needs.
136 We welcome any <a href="mailto:heimbach@mit.edu">feedback</a> you may wish to provide. </p>

139 <p class="headergray">30 March 2007: Ocean model captures diversity of marine microbes</p>
140 <p> Scientists at MIT have developed a new marine ecosystem model that allows its populations of
141 phytoplankton to realistically evolve, reflecting the diversity in populations in the natural world. This
142 should lead to a better understanding of the coupling between ocean and atmospheric chemistry.
143 The model makes use of ECCO's ocean state estimate to capture the physical environment in
144 which the ecosystem evolves. The study &quot;Emergent Biogeography of Microbial Communities in a
145 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 />

152 a large part of the ECCO products have been transfered to

154 different commonly used servers and software tools,
155 including DODS/OPeNDAP and LAS,
156 SDSC's DataCentral specialist Roman Olschanowsky
157 and MIT's Constantinos Evangelinos successfully
158 implemented DODS/OPeNDAP on top of SRB.
159 The SRB system allows fast and easy data access
160 across various disk and tape resources while ensuring
161 archiving/backup capability.
162 High speed access to the SDSC data using the SRB client tools is also

171 <p> A unique set of roughly 320,000 individual sub-surface measurements
172 of salinity (conductivity), temperature, and depth (CTD) taken by elephant
173 seals which carried bio-logging and telemetry devices
174 was added to the ECCO state estimation system as new
175 observational constraints.
176 The data were kindly provided by the <a href="http://biology.st-andrews.ac.uk/seaos/index.html" target="_blank">&quot;Southern Elephant Seals as
177 Oceanographic Samplers&quot; (SEaOS)</a> project involving

179 to go under the sea-ice which covers large parts of the Southern
180 Ocean poleward of 60S during austral winter and where in-situ data
181 are not available otherwise.</p>
