[Coral-List] AGU Fall Meeting Session PP013 - High Resolution, High Latitude Marine Proxies

[Dan Sinclair]

Today (11:59 pm EDT) is the last day for submitting abstracts to the AGU Fall Meeting (7-11 December).

We wish to advertise our session:

HIGH RESOLUTION, HIGH LATITUDE MARINE PROXIES (PP013)
Dan Sinclair, Nicholas Hitt, Ashley Davis (Victoria University of Wellington)

The oceans strongly influence the Earth’s climate and ecosystems. Understanding ocean dynamics on societally-relevant timescales is therefore essential. Ocean change naturally varies 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 evaluate if recent ocean changes are anomalous or a feature of 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 (e.g. deep-sea corals, coralline algae) 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 and analytical techniques.
