PIRATA-26 / TRIATLAS Conference and General Assembly

Banyuls-sur-Mer, France
16-20 October 2023

The 26th PIRATA / Tropical Atlantic Variability meeting and the final TRIATLAS meeting will be jointly organised in Banyuls sur Mer (France) from October 16 to 20, 2023. It welcomes participants from around the world working on the surroundingTropical Atlantic Ocean and surrounding continents.

Context

The Tropical Atlantic climate has important socio-economic consequences, but our understanding about its variability, its predictability and its impacts is still limited.

The “Prediction and Research Moored Array in the Tropical Atlantic” (PIRATA) program provides in situ observations and data time-series since 1997 that allow to address these challenges. It now consists in 18 open-ocean moorings that measure upper-ocean and surface atmospheric conditions and transmit their data in real-time for use in operational weather forecasting and ocean state estimation. The Pirata array also includes 3 equatorial moorings measuring the horizontal currents in the 300 upper meters. The array is maintained through a partnership between the U.S. (NOAA), France (Meteo France and IRD), and Brazil (INPE and DHN) and forms the backbone of the Tropical Atlantic Observing System (TAOS). The main purposes of PIRATA are to improve understanding of the tropical Atlantic Ocean, climate, and air-sea interactions; to aid in weather and climate prediction; and to monitor long-term changes in the ocean and atmosphere.

The Tropical and South Atlantic Climate-Based Marine Ecosystem Prediction for Sustainable Management (TRIATLAS) project is funded by the European Union’s Horizon 2020 research and innovation programme. TRIATLAS has focused on developing the understanding and the capacity (observational, modelling, and human) to best predict changes in the south and tropical Atlantic marine ecosystem and its societal impacts. TRIATLAS has brought together 34 institutions from Europe, Africa, and Brazil, contributing greatly to building a climate and marine ecosystem research community across the Atlantic. The project started in 2019 and will end in 2023.

In memory of Mathieu Rouault

Mathieu was a hands-on professor who loved field work and enjoyed working with multiple datasets and testing various hypothesis. Mathieu was internationally recognised for his expertise on the impact of the ocean environment on weather systems, forecasts and global trends.

Mathieu was passionate about science, his students, surfing, and research which included modelling Benguela El Niños. His research work included crossing the Agulhas current 12 times in four days, onboard the FRS Algoa in 1995, to prove how cloud conditions varied across the current; measuring waves south of Madagascar from a canoe and working in Still Bay on the local weather stations.

Mathieu joined the University of Cape Town in 1992 as a research officer. He was with the Water Research Commission until 2016 when he was appointed to a South African Research Chairs Initiative (SARChI) position for Ocean and Atmospheric Modelling in the Department of Oceanography. Strongly involved in TriATLAS, he also contributed to PIRATA through his deep involvement for it Southeastern extension.

Meeting details

Objectives

PIRATA and the broader TAOS have evolved considerably over the past two decades in response to changing research and operational needs. This progress would not have been possible without strong international commitment to PIRATA and the collaborative nature of the PIRATA and TAV communities. The main goal of the meeting is to advance tropical Atlantic science by bringing together a diverse group of tropical Atlantic researchers and stakeholders. TRIATLAS and the previous EU PREFACE and AWA projects have contributed to better understand TAV and its impacts on marine ecosystems, and to the TAOS. TRIATLAS brings new perspectives on marine ecosystems, fisheries, and social-ecological systems in general. We aim to discuss how these can be further integrated into tropical Atlantic variability and PIRATA communities.

Meeting Science Themes

Contribution to the development following themes focused on the Tropical and southern Atlantic are welcomed :

  • Ocean dynamics, air-sea interactions, extreme events
  • Tropical Atlantic variability and long-term changes
  • Instrumentation, best practices, and scientific uses
  • Biogeochemistry, marine ecosystems, and pollution
  • Social ecological systems, including fisheries

Workshop Format

The 5-day meeting will include a mix of 3.5-day plenary sessions and poster sessions, plus 1.5-day breakout sessions. Invited and plenary talks will provide a review of the current understanding and challenges identified as discussion topics to motivate discussion between participants during plenary and breakout sessions. The meeting will be held in-person (travel guidelines allowing) with virtual participation available.

Outcomes

A key outcome of the meeting is to foster interactions among diverse groups of national and international research communities. The organizing committee will share results with the broader community through a meeting report and special dedication to Mathieu Rouault through conference proceedings.
