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

97 <p>
98 A fifty year state estimate covering 1950 to 2000
99 is now available on the ECCO LAS server at <a href="http://www.ecco-group.org/eccolas/servlets/dataset" target="_blank">SDSC</a> The estimate was produced by the &quot;German ECCO&quot; <a href="http://www.ifm.uni-hamburg.de/" target="_blank">(GECCO)</a> group at the University of Hamburg
100 The product is described in
101 Koehl, A., D. Dommenget, K. Ueyoshi, D. Stammer, The Global ECCO
102 1952 to 2001 Ocean Synthesis Report No.40, March 2006. </p>

105 <p>
106 In collaboration with web designer Colleen Boisvert
107 ECCO has launched a new overall project web site.
108 Main purpose of this site is to provide an integrated view
109 of ECCO and it's follow-on projects
110 (ECCO-GODAE, ECCO2, GECCO, ...).
111 It is hoped that readers will get a clear understanding
112 of
113 ECCO's various activities, and will find
114 among ECCO's various ocean state estimation products
115 those which best suit their needs.
116 We welcome any <a href="mailto:heimbach@mit.edu">feedback</a> you may wish to provide. </p>
117 <p>&nbsp;</p>
118 <p class="headergray">30 March 2007: Ocean model captures diversity of marine microbes</p>
119 <p> Scientists at MIT have developed a new marine ecosystem model that allows its populations of
120 phytoplankton to realistically evolve, reflecting the diversity in populations in the natural world. This
121 should lead to a better understanding of the coupling between ocean and atmospheric chemistry.
122 The model makes use of ECCO's ocean state estimate to capture the physical environment in
123 which the ecosystem evolves. The study &quot;Emergent Biogeography of Microbial Communities in a
124 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 />

127 <p><span class="headergray">19 March 2007: ECCO products now hosted on SDSC's SRB archive.</span></p>
128 <p> In a collaboration between the San Diego Supercomputing Center
129 (SDSC) and ECCO,
130 a large part of the ECCO products have been transfered to
131 <a href="http://datacentral.sdsc.edu/resources.html" target="_blank">SDSC's Datacentral</a> and managed via <a href="http://datacentral.sdsc.edu/srb_resource.html" target="_blank">Storage Resource Broker (SRB)</a>. To make these data available to the community via
132 different commonly used servers and software tools,
133 including DODS/OPeNDAP and LAS,
134 SDSC's DataCentral specialist Roman Olschanowsky
135 and MIT's Constantinos Evangelinos successfully
136 implemented DODS/OPeNDAP on top of SRB.
137 The SRB system allows fast and easy data access
138 across various disk and tape resources while ensuring
139 archiving/backup capability.
140 High speed access to the SDSC data using the SRB client tools is also
141 available.</p>

144 <p>On December, 13, 2006, AGU awarded the Bowie Medal to Carl Wunsch &quot;For his wide-ranging research in the study of the ocean and its roles in shaping Earth's climate and its changes, and for unselfish cooperation in the field of physical oceanography.&quot;&nbsp; <a href="http://eapsweb.mit.edu/news/special_wunsch.html" target="_blank">Read Citation</a></p>

146 <p class="headergray">13 November 2006: Elephant seals serving ECCO</p>
147 <p> A unique set of roughly 320,000 individual sub-surface measurements
148 of salinity (conductivity), temperature, and depth (CTD) taken by elephant
149 seals which carried bio-logging and telemetry devices
150 was added to the ECCO state estimation system as new
151 observational constraints.
152 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
153 Oceanographic Samplers&quot; (SEaOS)</a> project involving
154 the <a href="http://www.smru.st-and.ac.uk/" target="_blank">University of St. Andrew's NERC Sea Mammal Research Unit (SMRU)</a> and the <a href="http://www.antarctica.ac.uk/" target="_blank">British Antarctic Survey</a>. The uniqueness of the data derives from the ability of seals
155 to go under the sea-ice which covers large parts of the Southern
156 Ocean poleward of 60S during austral winter and where in-situ data
157 are not available otherwise.</p>
