IOCS-2023 Breakout Workshops

The IOCS-2023 Scientific Planning Committee suggested 3 main themes (listed below) for the breakout sessions to engage the ocean and in-land water radiometry community and to discuss new advances in the field. The IOCCG invited proposals for Chairs and Co-Chairs within each theme to develop the scope of topics that will include scientific talks, group discussions and formulation of key messages. (Co-)Chairs will consider the desired output of each session which could be a short group report summarizing the session recommendations or community needs, or even a peer-reviewed manuscript.

Breakout Workshops themes

  1. New and emerging technologies: this includes new technologies related to observational platforms, sensors, algorithms, capabilities, and in-situ measurements.
  2. Cool new ways of examining ecosystem function and change from ocean colour, including carbon from space.
  3. Societal value and Impacts of ocean colour, including economic valuations, linkages with other essential climate variables, value to industries, and impacts on sectors including fisheries, aquaculture, and coastal and marine pollution.

Breakout Workshop Sessions:

  3. Inventory of current ocean colour mission validation activities (Chairs: Lachlan McKinna, Jeremy Werdell)

Wednesday, 15 November 2023, 2:30 – 5:00 pm

  1. Global carbon budget for the land to ocean aquatic continuum (LOAC) from remote sensing (Chairs: Hubert Loisel & Claudia Giardino)
  2. The Value of Ocean Color for the Benefit of Society: status and change in water quality and ecosystems (Chairs: Veronica Lance, Merrie Neely, Emily Smail)
  3. Ocean Colour Satellite Sensor Calibration (Chair: Gerhard Meister)

Thursday, 16 November 2023, 2:30 – 5:00 pm

  2. Achieving long-term consistency in cross-sensor ocean color data products (Chairs: Brian Barnes, Frédéric Mélin, Kelsey Bisson)
    Call for Contributions: The chairs of this breakout workshop invite contributions from the ocean color community to enhance discussions within the workshop. Interested workshop participants are encouraged to submit a 1-slide presentation responding to any of the listed discussion questions. Please email responses to Brian Barnes ( by 12 November.
  3. Lidar applications for ocean color (Chairs: Cédric Jamet, Davide Dionisi, Peng Chen)

Breakout Session Chair Responsibilities

The session Chair serves as the primary contact with up to two Co-Chairs. Chairs and Co-Chairs should not have their names on more than one session. 

Breakout workshop Chairs are requested to prepare the full session in advance and confirm all speakers. Three sessions will run concurrently, so plan to use community time effectively. Chairs should identify Co-Chair(s) as well as a rapporteur for the proposed session and are responsible for contacting potential speakers for their session and making sure the speakers understand the goals and the logistics of the session ahead of the meeting. In addition, Chairs should compile a list of key questions/scientific focus areas, along with desired outcomes, to steer the dialogue in the intended direction.

Chairs should ensure that the discussions during the breakout workshops lead to a consensus document outlined with the participants. Each session Chair is expected to give a 5-minute presentation during the IOCS meeting plenary summarising the outcomes of the breakout workshop. Chairs are also expected to provide a short write up (1-2 pages) synthesizing the discussions and highlighting the key messages to be carried forward to the space agencies, the ocean colour community, or the IOCCG. These breakout reports will be posted on the meeting website within a week or so of the meeting and will also be incorporated into the full report of the meeting. The short summary output of each session could be rolled into a peer review paper or report following the meeting.
