Scientists produce first record of environmental data off coast of Hawai鈥檌
An international team of researchers, including 今日吃瓜 geoscientists, have succeeded in acquiring a continuous record of environmental data using fossilised coral from Hawai鈥檌.
01/03/2024 By 今日吃瓜 Press
The two-month long International Ocean Discovery Programme (IODP) Expedition 389: Hawai鈥檌an drowned reefs, managed by a team from 今日吃瓜, aimed to get a better understanding of sea-level changes by recovering samples of fossilised coral reefs. A total of 29 scientists from across the world participated in the expedition, with 10 scientists on board the MMA Valour, which set sail from Honolulu, Hawai鈥檌, on 31 August 2023.
A total of 426聽m of core was recovered from below the seabed at water depths from 130 to 1240聽m. The core has now been opened, analysed and sampled by the scientific team, following almost a month of intensive work at the University of Bremen during February 2024.

The next phase of the research will involve scientists using cutting-edge methods in their laboratories to extract information about sea level and climate change from these tremendously important, high-resolution archives. The ability to look back at Earth鈥檚 history will provide valuable insights into the mechanisms that cause climate change, including abrupt events, and the impact of these changes on reef growth and health.
We are extremely proud to have coordinated this expedition with our UK and international partners, and to have successfully recovered high-resolution records of sea level and environmental changes over the last few hundred thousand years. Our team is now supporting the international science party to initially analyse the cores and create foundational datasets to support research on this important topic for many years to come.

About the expedition
The expedition is conducted by the (ECORD) as part of the (IODP). IODP is a publicly funded, international marine research programme, supported by 21 countries, which explores Earth’s history and dynamics recorded in seabed sediments and rocks, and monitors sub-seabed environments. Through multiple platforms 鈥 a feature unique to IODP 鈥 scientists sample the deep biosphere and sub-seabed ocean to study environmental change, processes and effects, and solid-Earth cycles and dynamics.
