The Estimating the Circulation and Climate of the Ocean (ECCO) consortium, a joint venture led by MIT, NASA’s Jet Propulsion Laboratory, and Scripps Oceanographic Institution combines observations and the MITgcm to obtain a more realistic understanding of ocean circulation, how it evolves over time, and its impact on global climate.

Between May 16-18 members of the extended ECCO family met at MIT to share news of what science is being done using ECCO and to discuss “needs, synergies, challenges, and a roadmap” going forward.

The meeting kicked off with a general overview of the global decadel ECCO effort with Gael Forget (MIT) giving a product overview of ECCO v4, Ichiro Fukumori (JPL) and Ian Fenty (JPL) providing an overview of the main updates in forthcoming release 3, Detlef Stammer (U. Hamburg) appraising attendees about GECCO2 and related activities, and Dimitris Menemenlis (JPL) wrapping up with an overview of ECCO-IcES.

There were science sessions on  Sea Level (chaired by Dimitris Menemenlis), two for Ocean Circulation Variability and Change (one chaired by Gael Forget (MIT), the other by Christopher Hill, MIT), Coupling ECCO to the Cryosphere (chaired by Ichiro Fukumori), Emerging Applications (chaired by Matt Mazloff, Scripps), Ocean Acoustic Tomography (chaired by Patrick Heimbach, MIT/ U. Texas Austin), and Ocean Biogeochemistry and Ecology (chaired by Dimitris Menemenlis.)
