Session ID#: 25013

Session Description:
The oceans strongly influence climate and provide resources to much of the planet’s population. Understanding ocean dynamics on societally-relevant timescales is therefore essential. The oceans naturally vary on timescales of months to millennia, but quality instrumental records are scarce prior to the satellite era, and seldom span more than a few decades. We must therefore use proxy records to characterize ocean dynamics on timescales longer than our narrow window of perception. Marine sediments provide longer-timescale information, but seldom at sub-centennial resolution, leaving a critical gap in the decadal-to-centennial timescales in which ocean dynamics remain poorly characterized. In low latitudes, this gap is filled by tropical corals, but only recently have high resolution proxies emerged capable of providing decadal-resolution ocean data in temperate to polar waters. In this session, we invite submissions in the emerging field of high-resolution high-latitude marine proxies, including new archives, new proxies and new analytical techniques.
