A Volcanic Lost World Research Symposium
2025-05-06 - 2025-05-07 | australian national maritime museum, Australian National Maritime Museum, Sydney, Australia
‘A Volcanic Lost World’: A research symposium to develop a deeper understanding of Lord Howe Rise and the South Tasman Sea
The Lord Howe Rise and South Tasman Sea Research Symposium will take place on 6-7 May 2025 at the Australian National Maritime Museum in Sydney, organised by the High Seas Alliance and WWF with scientific expertise from the Deep-Ocean Stewardship Initiative, and supported by the Australian Government.
The Symposium will bring together around 80 eminent researchers, thinkers, government representatives and practitioners from a range of disciplines to share knowledge, research and experience. The aim is to collectively build a rich picture of the Lord Howe Rise and South Tasman Sea areas, drawing on historical knowledge and research through to recent and ongoing initiatives.
The main proceedings will comprise the presentation of around 30 papers by leading scientists on a range of topics
relevant to the areas, from leatherback turtles to cold-water corals; from the biogeography of the areas to cultural and ecological knowledge of species and uses. In addition, two panels will be convened on First Nations Knowledge and Ocean Governance. The opening keynote will be delivered by James Bradley, author of Deep Water, a hymn to the beauty, mystery and wonder of the ocean. High-level remarks will be delivered by Dr Filimon Manoni, the Pacific Ocean Commissioner, and Ambassador Peter Thomson, the UN Secretary General’s Special Envoy for the Ocean.

BBNJ PrepComm
2025-04-14 - 2025-04-25
1st Session of the Preparatory Commission for the Entry into Force of the BBNJ Agreement and the Convening of the First Meeting of the Conference of the Parties to the Agreement
The first session of the BBNJ Preparatory Commission begins today at the United Nations Headquarters in New York and will take place over the next two weeks (12-25). DOSI delegates are on the ground, ensuring that the deep sea is a central part of the conversation. This historic meeting is setting the stage for the entry into force of the BBNJ Agreement, which aims to protect marine biodiversity in areas beyond national jurisdiction (ABNJ) — nearly two-thirds of our global ocean.
Delegates will decide key structural elements:

Rules of procedure for the future Conference of the Parties (COP)
Terms of references and rules of procedure of the subsidiary bodies established under the Agreement
Selection process for the Scientific and Technical Body
Location and structure of the Secretariat
Financial and implementation mechanisms

As the world takes this next step toward a unified ocean governance framework, DOSI is working towards advancing strong, science-based approaches in policy decisions to ensure the deep sea — Earth’s largest, least known ecosystem — is effectively protected.
