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