Aloha Hawaii – Call for participants to sail on IODP Expedition 389 (Hawaiian Drowned Reefs) in 2023 announced.

Hi All, very exciting news. The official call for scientists to sail on International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs) has just been announced by all IODP member countries.

The offshore phase of IODP Exp. 389 is scheduled for a maximum 60 days within a window from mid-August to end October 2023. The objectives of this expedition are to recover fossil coral reef cores from an amazing sequence of drowned coral reefs that are preserved around the flanks of the Big Island of Hawaii. See the project summary and the Expedition homepage for more details. You can also consult a concise summary science article about the the expedition in  ECORD Newsletter #35 (Dec 2021).

The project will use an innovative, sea bed rock drill to recovery continuous fossil reef samples from seabed depths down to -1500 m that span the period back to ~500-600,000 years. These samples will allow us to reconstruct an unparalleled record of past sea level and climate changes (including El-Nino) and coral reef responses.

To learn more about the scientific objectives of this expedition, life at sea, and how to apply to participate, please join us for a web-based seminar on Friday 9 September 2022 at 1pm UTC. To register, please visit:

In meantime feel free to contact me directly if you want to know more about the project.
