We are excited to let you know that IOCCP is co-organzing and co-sponsoring the 53^rd International Colloquium on Ocean Dynamics which will take place on 16-20 May 2022 in Liege, Belgium. The theme of the 53rd Liege colloquium is "Low oxygen environments in marine and coastal waters: Drivers, consequences, solutions." The event will investigate new developments and insights related to deoxygenation in open and coastal waters. The colloquium is a contribution to the Ocean Decade program Global Ocean Oxygen Decade (GOOD). Please see the Colloquium website for a complete list of sessions, including one on "Deoxygenation: observing and modelling" co-convened by Véronique Garçon, IOCCP Co-Chair. Véronique and Maciej Telszewski, IOCCP Director, represent IOCCP on the Colloquium Organizing and Scientific Committee.

Abstract submission deadline is on 16 January 2022, and early-bird registration will close on 30 March 2022. Feel free to use the attached flyer to spread the announcement among your colleagues.

This is a friendly reminder that there is still a chance to submit an abstract for the 2022 Ocean Sciences Meeting (OSM 2022) which will be held on 27 February - 04 March 2022 in Honolulu, HI, USA. This year's conference format allows for in-person, virtual or hybrid attendance. See here for details on which registration option is most suitable for your needs: https://www.aslo.org/osm2022/in-person-virtual-or-hybrid/. In the Conference program you will find many sessions relevant for ocean carbon and biogeochemistry observations and modelling. A complete list of scientific sessions can be found here: https://www.aslo.org/osm2022/scientific-sessions/

Abstract deadline of 11:59 pm EDT on 29 September 2021 will be strictly enforced. Please note that abstract fee was waived for submissions by attendees from developing countries. See here for detailed abstract guidelines: https://www.aslo.org/osm2022/abstract-guidelines/

­Please join the Global Ocean Oxygen Network (IOC Expert Working Group GO2NE) for a new session of its webinar series on ocean deoxygenation. This 9^th webinar will take place on 23 September 2021 at 14:00 UTC. The webinar will feature presentations by: Dante Espinoza-Morriberon (Instituto del Mar del Perú) on "Numerical modelling of oxygen variability and deoxygenation trends in the Southeastern Pacific," and Renato Salvatteci (Kiel University, Germany) on "Paleoceanographic evidence for smaller fish species in a warm and oxygen-poor ocean." Recordings from this and past webinars are available from here: https://www.youtube.com/results?search_query=unesco+go2ne
