Time Agenda Presenter Presentation
09:00 to 10:30

Breakout Groups

Breakout Group 1: AMOC observations, state and variability. They will explore ways to optimize paleo-observational networks to ensure reliable AMOC reconstructions over relevant timescales.
Breakout Group 2: AMOC Mechanisms and Predictability will focus on how paleoceanographic and paleoclimatic data can be used to test proposed AMOC mechanisms and predictability.
Breakout Group 3: Climate Sensitivity to AMOC: Climate/Ecosystem Impacts will focus on merging the evidence for AMOC impacts on the Earth system from modern and paleo data.


11:00 to 12:30

Final discussion and breakout group summaries



14:00 to 16:00
(Optional) Writing and planning session to summarize the results of the workshop and assign follow-up writing tasks. All attendees are invited to join if they wish to contribute.
