Ocean Decade Conference 2027: ocean science in Rio

The Ocean Decade Conference is an international meeting about using knowledge of the ocean to address challenges facing coastal communities, the economy and the environment. Its main conference takes place on 7–9 April 2027 in the Pier Mauá warehouses. It is jointly organised by UNESCO’s Intergovernmental Oceanographic Commission, Brazil’s Ministry of Science, Technology and Innovation, and the City of Rio de Janeiro.

What will the discussions cover?

The programme focuses on practical solutions, with subjects including coastal resilience, the ocean economy, food systems, biodiversity, pollution, ocean observations and data. Plenary and parallel sessions bring together the scientific and professional community, alongside government bodies and other organisations working with the ocean.

The conference is part of the wider Ocean Decade Week. Partner events on 5–6 April precede the main programme but take place at separate venues around the city. If you plan to attend several parts of the week, keep the address for each event you choose.

Main dates and participation

For the main conference, plan around 7–9 April and Pier Mauá. The official website publishes registration requirements, programme information and participation options. Check the organiser’s rules for your chosen meetings: this professional conference has its own admission arrangements, separate from visiting the waterfront.

Travelling to the port area

In your enquiry to Hola Taxi, specify Pier Mauá, the date and your departure address, such as your hotel. If you are attending a partner event elsewhere first, add that journey separately. Discuss the return once you have chosen your final session. For an airport journey, include GIG or SDU and your flight details.
