The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 377 Arctic Ocean Paleoceanography (ArcOP) aboard a Mission Specific Platform (MSP) provided by the ECORD Science Operator. To learn more about the scientific objectives of this expedition, life at sea, and how to apply to sail, please join us for a web-based seminar on Tuesday, May 26, 2020 at 8:00 AM EDT/ 1:00 PM BST. The overall goal of the Expedition 377 is the recovery of a complete stratigraphic sedimentary record on the southern Lomonosov Ridge to meet the highest priority paleoceanographic objective: the continuous long-term Cenozoic climate history of the central Arctic Ocean. Furthermore, sedimentation rates two to four times higher than those at the site of IODP Expedition 302: ACEX permit higher-resolution studies of Arctic climate change in the Pleistocene and Neogene. This goal can be achieved by careful site selection, appropriate drilling technology, and applying multi-proxy approaches to paleoceanographic, paleoclimatic, and age-model reconstructions. Opportunities exist for researchers (including graduate students) in all specialties. While other expertise may be considered, specialists in the following fields are required: sedimentology, micropaleontology, palynology, organic geochemistry, inorganic geochemistry, structural geology, paleomagnetics, microbiology, physical properties, geophysics, stratigraphic correlation, and downhole logging. The deadline to apply is June 19, 2020.
