Join us for a 5-day ECCO hackathon at the Caltech Keck Institute for Space Studies 14-18 October 2024. Participants will learn how to access and utilize ECCO V4 global ocean and sea-ice state estimates for various ocean and climate analyses. Participants will have the opportunity to work on team projects that focus on different kinds of analysis of ECCO estimates, including comparisons with data. Don't miss this chance to enhance your expertise, collaborate with peers, and contribute to advancing our understanding of ocean circulation and climate.

The ECCO Annual Meeting was held at the University of Texas at Austin on 20-22 March, 2024. The first two days focused on ocean dynamics, high-resolution applications, biogeochemistry, and new frontiers. The third day focused on algorithm and tool development, closing with a discussion of broader topics including how ECCO can address societally-relevant issues and ways to engage the broader research community and students.

[12-Dec-2022] Many ECCO-related presentations are being presented at the 2022 AGU (American Geophysical Union) Fall Meeting during the week of December 12th. This meeting regularly attracts over 25,000 attendees from 100+ countries to share research and network.
[03-Mar-2022] This tutorial at Ocean Sciences 2022 focuses on global multidecadal ocean state estimation: the challenge of reconstructing the three-dimensional, full-depth time-evolving ocean state by combining diverse satellite and in-situ ocean and marine ice data with numerical models in a rigorous and quantitative framework.
[02-Mar-2022] This session invites submissions of adjoint model applications to studying the ocean so as to explore the widening range of these investigations. Contributions are sought from all disciplines of oceanography as well as studies concerning computational aspects of model adjoints.

[12-Jan-2022] Our interactive tour guides viewers through the nearly 140 ECCO-related publications and theses released in 2021, a 42% increase over 2020 (view ECCO Research Roundup 2020). The areal coverage of these studies is highlighted on interactive globes, parsed into six categories (Polar Pursuits, Air-Sea Assessment, Life Lessons, Circulation Consideration, Eddy Evaluation, and Other Observations).

[26-Oct-2021] The PO.DAAC is pleased to announce the public release of ECCO Version 4, Release 4b (V4r4b), an errata for the ECCO Version 4 revision 4 (V4r4) ocean and sea-ice state estimate.
[03-Sep-2021] The PO.DAAC is pleased to announce the public release of the ancillary data for the (Estimating the Circulation and Climate of the Ocean) ECCO Version 4 Release 4 (V4r4) ocean and sea-ice state estimate.
[26-May-2021] ECCO's multi-decadal global ocean state estimate was used to validate ocean temperature changes derived from a new method known as seismic ocean thermometry.
[03-May-2021] ECCO simulations will be configured to plan field work and test hypotheses for NASA's "Salinity and Stratification at the Sea Ice Edge" (SASSIE) campaign. Three ECCO simulations — each with its own horizontal grid spacing and vertical resolution — will be employed to address specific science questions.
[27-Apr-2021] The PO.DAAC is pleased to announce the public release of the ECCO Version 4 release 4 (V4r4) ocean and sea-ice state estimates.
[19-Nov-2020] The ECCO consortium will host a town hall on Thursday, December 3, 2020 from 10:30-11:30 PT, during the 2020 AGU Fall Meeting. It will include research highlights with salient examples drawn from diverse projects, announcements about new products (e.g., Version 4, Release 5), and instructions for how to employ ECCO for budget analyses and other investigations.
[21-Feb-2020] ECCO was well represented at Ocean Sciences Meeting 2020 with more than 30 presentations, posters, and e-lightning talks. The application of ECCO spanned a wide range of fields including observational system design, ocean biogeochemistry, ocean/ice-sheet interaction, global ocean heat and salt transport, and regional sea-level rise.
[20-Feb-2020] The ECCO Consortium hosted a public town hall meeting at Ocean Sciences Meeting 2020 in San Diego, CA. The presentation included descriptions of the latest ECCO "Central Production" state estimate (Version 4, release 4), several example applications of the state estimate and adjoint tool for climate studies, and a survey of some Python, Julia, and Matlab tools developed to faciliate analysis.
[09-Dec-2019] The ECCO consortium hosted a town hall at the 2019 AGU Fall Meeting to introduce the latest global ocean and sea-ice state estimate Version 4 release 4 (ECCO V4r4).

 ECCO Summer School 2019
[31-May-2019] The ECCO consortium hosted a two-week summer school for graduate students and early career scientists on global ocean state estimation in support of climate research. The school, held 19-31 May 2019 at Friday Harbor Laboratories in Friday Harbor WA, introduced tools and mathematics of ocean state and parameter estimation and their application to ocean science through a mix of foundational lectures, hands-on tutorials, and projects.
[14-May-2019] Recent research indicates that global-scale seawater pathways may play less of a role in Earth's heat budget than traditionally thought. Instead, one region may be doing most of the heavy lifting.
[26-Mar-2019] Research shows that Jakobshavn Glacier - Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years - has made an unexpected about-face. Using the ECCO ocean model, researchers have now traced cooler water not seen since the 1980s to a current that carries water around the southern tip of Greenland and northward along its west coast.
