2025 International Ocean Colour Science Meeting
Darmstadt, Germany, 1-4 December 2025

The sixth International Ocean Colour Science (IOCS) meeting will be convened by the International Ocean Colour Coordinating Group (IOCCG) hosted by The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), and the European Space Administration (ESA), with the support of the Copernicus Programme from the European Commission from 1-4 December 2025 at the Darmstadtium in Darmstadt, Germany. Associated short courses and side meetings will be held on 5 December 2025.

The IOCS meeting covers optical radiometry of all water types, and serves as a venue for open communication between the scientific community and the space agencies. The meeting is structured around consensus recommendations to the agencies that will help to inform future missions, and drive forward science and application. It also provides a venue for the community to liaise directly with representatives from the respective agencies.

The overarching theme for IOCS-2025 is “Ocean Colour: serving Earth system science & our society” and will feature plenary sessions, including interactive panel discussions and town halls, and breakout sessions that allow for participant interaction and feedback to the agencies, as well as poster sessions for participants to share and discuss relevant science and applications.
