The International Ocean Discovery Program drilling cruise to the Agulhas Plateau will investigate the interplay between changes in global climate, ocean depth and ocean circulation. It aims to recover first-ever deep geologic samples from this large oceanic plateau situated approximately 500km south of South Africa.
Scientist on this expedition will investigate the Pliocene-Pleistocene atmosphere-ocean-cryosphere dynamics of the Pacific Antarctic Circumpolar Current (ACC), and their role in regional and global climate and atmospheric CO2 based on sediment records with the highest possible stratigraphic resolution.
This expedition will explore changes in the Antarctic Ice Sheet over long time periods by studying sediment deposited by icebergs and changes in sea ice, ocean currents, and winds.
A team of 116 ship crew, scientists, technicians, and communicators takes to the Amundsen Sea, Antarctica’s fastest-warming sea, aboard the JOIDES Resolution. Over the course of their two-month mission, they plan to drill at least five sites beneath the seabed and bring home sediment samples that are millions of years old, in order to recreate the history of the West Antarctic Ice Sheet (WAIS).
Expedition 374 investigates how the West Antarctic Ice Sheet (WAIS) has evolved with climatic and oceanic change over the past 20 million years. The Ross Sea is an ideal location for this study because it is highly sensitive to changes in ocean heat flux and sea level. This work will lead to a better understanding of Antarctic ice sheet sensitivity to warmer climates.
