November 2017: ECCO Tutorial @ Ocean Sciences 2018:
The ECCO project will hold a workshop during Ocean Sciences 2018 in Portland, OR. More details regarding the workshop's agenda to follow.
Title: ECCO Workshop: How to use the latest ECCO Ocean State Estimate
Date and Time: Thursday, February 15, 2018: 12:45 PM - 1:45 PM
Location: Oregon Convention Center, F152
July 2017: ECCO version 4 release 3, covering 1992-2015, now available online:
The new release 3 extends the Version 4 estimate using additional observations. The product also incorporates improvements in modeling and estimation. A summary document describes details of the changes. Also available are descriptions of how to evaluate property budgets and how to reproduce the results and generate additional fields using MITgcm..
June 2017: A new 20-yr ECCO climatology is now available online:
ECCO version 4 has been used to calculate a uniform 20-year climatology as a time-mean over the period 1994-2013. The climatology is readily accessible as Matlab files.
Associated pictorial atlas and descriptions are available in the DSpace@MIT ECCO Community Collection long-term archive. So far these include:

May 2016: Joint ECCO-Production and ECCO-IcES Meeting at MIT:
The ECCO-Production and ECCO-IcES groups will hold a joint project meeting at MIT from 16-18 May 2016. A preliminary meeting agenda is now available online.
Mar 2016: ECCO version 4, release 2 (ECCO v4-r2) now available online
As compared with the earlier release, ECCO v4-r2 benefits from a few additional corrections as documented in this note. ECCO v4-r2 (see products) further includes the full suite of observational inputs and forcing fields, as well as an interpolated version of the state estimate fields (on a half degree lat-lon grid). The ECCO v4 model settings (see model) have also been simplified to facilitate re-runs of the state estimate solution. This capability allows any user to generate model output that may not be available online (see the ECCO version 4 user guide).
May 2015 [UPDATED Mar 2016]: paper available describing ECCO version 4, release 1 (ECCO v4-r1) in details
Following the release in February 2014 (See products) of a new-generaption, global, bi-decadal state estimate (ECCO version 4, release 1), a paper has been published and highlighted in Geoscientific Model Development that provides a detailed description of the model and estimation configuration, the observational data streams, and basic properties of the solution:
