International Ocean Colour Science Meeting 2025

Monday 1 December 2025 - Friday 5 December 2025

Location: Darmstadt, Germany

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 Agency (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, at EUMETSAT Headquarters in Darmstadt.

PML delegates will be taking part in the IOCS meeting, which 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.
