South & Central Atlantic Regional Scientific Research Working Group
he Central and South Atlantic RSR-WG is coordinated by Dr Kirsty McQuaid (South Africa), and temporarily by Prof Kerry Howell (UK) while we seek a new co-lead from South America. The RSR-WG consists of over 80 members and meets on a biannual basis.
Activities within the RSR-WG initially focused on producing a review of the deep-sea and shelf benthos of the Central and South Atlantic. The review, titled “Review of the Central and South Atlantic Shelf and Deep-Sea Benthos: Science, Policy, and Management” and published in 2023, synthesises contributions from 45 co-authors from 18 nations. This represents the most comprehensive summary to date of some of the world’s least explored ocean space. The review identifies particularly data-poor areas and proposes recommendations for future research and management in the region. Read more here.
Members of the RSR-WG have also been busy at sea,
undertaking research cruises to gather data and build knowledge of Central and
South Atlantic deep-sea ecosystems. This has included exploration of coelacanths
and their ecosystems, baseline environmental studies of the Argentine
deep sea, biodiversity surveys of Ascension
and St Helena Islands, and a capacity building cruise led by Early Career
Researchers in South Africa.
The current focus of the RSR-WG is developing Expressions of Interest for Schmidt Ocean Institute’s calls for collaborative, multidisciplinary research. This is in support of the Challenger 150 Programme’s plans to map Atlantic deep-ocean life. To date several applications have been submitted for the South-western Atlantic to explore deep-waters in Argentina and Uruguay. These were successful and will take place later this year. Further Expressions of Interest have been submitted for the Brazilian and West African margins. The group is now focused on seeking funding for basin-scale collaborative research.
