By investigating modern and ancient currents in the Greenland Sea, Expedition 403 will collect crucial data to ground-truth climate models of projected future CO2, temperature, ocean temperature, sea ice, and present Earth ice sheet stability. Expedition 403 stands out in significance not only because it will return with data to better understand some of the most pressing details of our changing climate, but also for its historic role as the last expedition of the JOIDES Resolution within the International Ocean Discovery Program.

In a bid to shed light on the enigmatic process of mantle exhumation during lithospheric extension, the International Ocean Discovery Program announces Expedition 402. Initiated in response to the ongoing debate over the nature and genesis of continent-ocean transitions, sparked by the discovery in the 1980’s of exposed mantle in the continent–ocean transition (COT) west of Iberia, this expedition aims to address critical questions about the mechanisms of continental break-up, the inception of seafloor spreading, and the nature of COTs.

The exchange of seawater between the Mediterranean Sea and Atlantic Ocean has a tremendous impact on global climate both through ocean chemistry and its circulation patterns. By studying the opening and restriction of gateways between these bodies of water, Expedition 401 seeks to uncover secrets about past climates buried beneath hundreds of meters of water and rock. This expedition forms part of the larger IMMAGE Project, the first land-to-sea drilling project.
