Session Proposal: North Atlantic Paleoclimate: Sedimentary Archives of Climate, Ocean Circulation, and Ice Sheet Interactions (AGU25)

PP022
North Atlantic Paleoclimate: Sedimentary Archives of Climate, Ocean Circulation, and Ice Sheet Interactions

Session ID#: 249028

Session Description:
Feedbacks between North Atlantic climate, ocean circulation, and ice sheets were a key influence on and often drivers of global climate variability during the Pliocene and Pleistocene. Recent International Ocean Discovery Program (IODP) expeditions in the North Seas, Fram Strait, northwest Greenland Margin, Iceland Basin, Mediterranean-Atlantic Gateway, and Iberian Margin have greatly expanded sedimentary records in the region, enabling high-resolution, continuous, and state-of-the-art proxy reconstructions of North Atlantic paleoclimate and paleoceanography through the Pliocene and Pleistocene. Analysis and synthesis of these sedimentary paleo-records provide insights into major climatic shifts through this period. We invite submissions that present, employ, or are relevant to sedimentary records of the North Atlantic Ocean and its proximal seas from the Plio-Pleistocene. These may include studies of sediment physical and magnetic properties, organic and inorganic geochemistry, biostratigraphy, and cyclostratigraphy. We also welcome contributions that synthesize existing records or expand their spatial or temporal resolution and extent.
