ArcSTRAT - Arctic Ocean Stratigraphic and Paleoclimate Conference

The Arctic is currently undergoing the most dramatic climatic changes on Earth, with the Arctic Ocean rapidly moving towards a “blue” (summer sea ice free) state. To assess how a “blue” Arctic will respond to and drive an increasingly warmer future, in the absence of observational records, requires robust archives from the geological past. Such conditions existed during the Pleistocene interglacials and potentially during the middle Pliocene warm period, when geological and oceanographic conditions were comparable to today, yet substantial insolation changes led to pronounced high northern latitude warming, associated with reduced or absent summer Arctic sea ice and smaller-than-present ice sheets.

ArcSTRAT will bring together scientists from all around the world to discuss the constraints to date and correlate past climate archives from across the Arctic Ocean.

Such warmer-than-present periods represent valuable analogues to a potential future “blue” Arctic, yet despite the recovery of 100+ sedimentary records from the Arctic Ocean covering these time periods, empirical and numerical studies remain scarce, and the research community is currently unable to adequately characterize these “greenhouse climate states”, due to severe stratigraphic uncertainties.

The ArcSTRAT – Arctic Ocean Stratigraphic and Paleoclimate Conference in October 2024 brings together geoscientists from all over the world to one meeting discussing the current constraints to date and correlate past climate archives across the Arctic Ocean.

ArcSTRAT aims to provide a forum where scientists can present their work and discuss their ideas on (1) the current status of the stratigraphic framework for the Arctic Ocean, (2) recent methodological advances to overcome the existing constraints, and (3) a road map to create synergies between expert groups and laboratories to solve all obstacles in Arctic Ocean stratigraphy during the Pleistocene and the Pliocene.

Conference Topics:

Current Arctic stratigraphic framework
Current knowledge of Quaternary climate evolution
Developing an Arctic Ocean multi-stratigraphic toolbox
Application of multi-stratigraphic and proxy toolbox
