A large contingent of the ocean colour community—over 270 research scientists and agency representatives from around the world—gathered in St. Petersburg Florida, USA for the 6th International Ocean Colour Science (IOCS-2023) Meeting .
The IOCS-2023 was held from 14 – 17 November 2023, and was preceded by the GEO AquaWatch Biennial Meeting. It was also the venue for several training courses and associated research team meetings. A wholehearted thanks goes to our host, the University of South Florida (USF) St. Petersburg Campus, and especially the many colleagues and volunteers from the College of Marine Science for an outstanding job in helping to organize and support the event. We also thank the other main meeting sponsors NASA, NOAA and OCB, as well as the sponsoring agencies of the IOCCG, who all made the meeting possible. Thanks to the members of the Organizing and Scientific Planning Committee for their help in structuring the meeting. See note from the IOCCG Chair to all participants.
Dear IOCS-2023 participants,
On behalf of the IOCCG Project Office, all members of the IOCCG Committee, the IOCS Scientific Planning Committee and the IOCS Organising Committee, I write to thank you for all your contributions at the IOCS Meeting at the University of South Florida, St. Petersburg, USA.
According to all the feedback we have received, the IOCS meeting was well received by the community. It was a success only because of all your contributions. I would like to thank all the keynote speakers, the poster contributors, plenary session chairs, breakout session co-chairs, all the space agency representatives, and all those who used this opportunity to have side meetings of working groups and to organise training courses, and of course, everyone of you for your participation in the events.
With best regards,
The overall goal of the IOCS is to improve communication between research scientists and space agency representatives, and to advance ocean colour radiometry research.
The meeting had six invited keynote talks that covered recent technology, applications, and the economic value of ocean colour. A special opening keynote was delivered by Dr. Howard Gordon, who participated in the development of the Coastal Zone Colour Scanner (CZCS), and delightfully walked the audience through the beginnings of ocean colour remote sensing. Other plenary talks included mission updates and applications from various space agencies and research organizations, and a much appreciated talk by previous chair Cara Wilson on the status of all the recommendations and actions that have emerged from IOCS meetings.
Nine very interactive breakout workshops allowed for groups to form consensus on the way forward on many aspects of ocean colour science. Daily poster sessions allowed many participants to share their research. Each poster session began with lightning talks that were very well received, and allowed the main findings to be communicated quickly to the entire audience ahead of the more detailed discussions with colleagues during the session.
Presentations, photos, and other material from the IOCS-2023 meeting material is now available on the meeting website at iocs.ioccg.org/iocs-2023-meeting. Reports from the breakout workshops are still being collated. Recommendations from all the previous IOCS meetings are also now available on the IOCS website at iocs.ioccg.org/iocs-recommendations, and will be updated with new recommendations that emerged from the 2023 meeting. Recommendations aimed at the ocean colour community will be communicated in future news bulletins.
IOCCG Platt Scholarship – Stories from the Scholars: David González Rivas
The opportunity to conduct a two-month research visit in Dr. Dierssen’s Lab, Coastal Ocean Laboratory for Optics and Remote Sensing (COLORS), was a profoundly enriching experience. I met and collaborated with fellow students and alumni engaged in diverse lab projects, fostering connections with colleagues exhibiting varied interests and backgrounds. From the very beginning, I felt welcomed into Dr. Dierssen’s team. I was invited to participate in their sampling sessions and received comprehensive training on utilizing the Field Spec Pro ASD as an integral member of the laboratory. This experience was not limited to UCONN and nearby field sampling, as Dr. Dierssen also invited me to conferences near Boston and a field project in Ottawa, Canada. These experiences allowed me to learn about new applications and uses of hyperspectral sensors and their utilizations.
One notable aspect of this research stay was, of course, the ongoing development of the scholarship project. I received valuable feedback throughout this period, contributing to the refinement of our work. Also, having the opportunity to attend and participate in the IOCS-2023 meeting proved to be an exceptional experience. This provided the chance to reconnect with colleagues from Lab COLORS and facilitated meeting other professionals. Interacting with attendees during poster sessions and informal gatherings while also attending various conferences offered invaluable insights and networking opportunities. This type of experience provides me with great confidence, stimulates me to continue learning, and, above all, generates a cultural and academic exchange that hopefully will continue to grow. I am very grateful to the entire Ocean color community and the IOCCG for the opportunity to work with the lab members and former members, and to COLORS, and especially to Dr. Dierssen, for the warmth and all the support shown since the first day we started talking.
David’s research in the COLORS lab focused on using ocean color data to understand shrimp farms water discharge in the coastal ecosystems of the Gulf of California. The final report of his scholarship work is being finalized and will be available on the IOCCG Platt Scholars webpage.
Applications for the 2024 Platt Scholarship closed on 12 January 2024 and selections are underway. The 2024 Scholar will be notified and announced in early March 2024.

Sentinel-3 OLCI products and the TSIS-1 solar irradiance reference spectrum
Sentinel-3 OLCI Level-1 top-of-the-atmosphere radiance products will be moving to the Total and Spectral Solar Irradiance Sensor-1 (TSIS-1) solar irradiance reference spectrum.
The difference between the current Thuillier et al., 2003, solar spectrum and TSIS-1 is significant for OLCI L1 radiances and exceeds 3% for bands at 400, 412 and 560 nm. Operational switch to the TSIS-1 solar spectrum will occur in the first half of 2024. At the same time, OLCI-A and -B full mission datastream reprocessed with the new spectrum will become available.
The community will be further informed about the operational switch and provided with supporting documentation.
