GO2NE Webinar Series

Welcome to the Global Ocean Oxygen Network (GO2NE) webinar series archive, a regular online seminar series that focuses on the depletion of oxygen in the marine environment – ocean deoxygenation. Organised and hosted by IOC/UNESCO, each one-hour webinar is run by a guest moderator and two invited speakers. To support the diversity of the scientific community, the webinar series aims for an equal balance of early-career and senior scientists, gender, and geographical representation.

GO2NE Webinar 12 June 2024 No 29 World Oceans Day

"The 29th Global Ocean Oxygen Network (IOC Expert Working Group GO2NE) webinar was a special session of its series on ocean deoxygenation to mark World Oceans Day 2024.
The webinar took place on 12 June 2024, 1500 CEST. It featured presentations by GO2NE Co-Chairs Andreas Oschlies and Caroline Slomp, and expert working group member Karin Limburg, speaking on the latest global scientific efforts to understand, mitigate and adapt to ocean deoxygenation, and the most recent work of GO2NE and its members."

Speakers:
Andreas Oschlies (GEOMAR, Germany)
Caroline Slomp (Radboud University, The Netherlands)
