Overview and meeting objectives

Coastal Ocean and Shelf Seas Task Team – International Coordination Meeting (COSS-TT ICM)

Ifremer, Brest-Plouzané, France

17-20 June 2025

REGISTRATION EXTENDED TO 15 APRIL 2025

The main goal and central mission of the COSS-TT is international coordination in support of new science and expertise leading to improvements in coastal ocean prediction and forecast systems. COSS-TT works within OceanPredict towards the provision of a sound scientific and expert basis for sustainable multidisciplinary downscaling and forecasting activities in the world’s regional and coastal oceans. The strategic goal of the COSS-TT is to help achieve a truly seamless framework from the global to the coastal/littoral scale. A major contribution is to address the particular challenges on monitoring and forecasting in coastal areas and regional seas, where the majority of human marine activities take place. As these are also the areas of enhanced exploitation of marine resources, the COSS-TT has a mission well aligned with society’s needs and benefits.

International coordination meetings of the OceanPredict Coastal Ocean and Shelf Seas Task Team (COSS-TT) gather a broad community of scientists, engineers and experts around presentations and discussion themes in support of coastal ocean forecasting. The COSS-TT is well-aligned with relevant international initiatives under the UN Ocean Decade, such as the CoastPredict program, the SynObs project, the Decadal Collaborative Center for Ocean Prediction and the Decadal Collaborative Center for Coastal Resilience.

Presentations

The meeting will consist of oral and poster presentations selected through the abstract submission process and organized by the meeting themes.

Length of talks and Q&A to be confirmed.
We expect to record presentations and put them on the website after the meeting and will ask permission for online display via the abstract submission form.
We are planning to open the COSS-TT 2025 Special Issue in Ocean Dynamics after the meeting.
