PC44D:
Placing the North Pacific in a Global Climate Framework I Posters


Session ID#: 28267

Session Description:
The North Pacific has proven a difficult place from which to generate high quality paleo-environmental reconstructions, related to (among other factors) a shallow carbonate compensation depth in the marine environment, a dearth of surviving proximal ice sheets, and challenging weather. As such, in spite of its importance to modern climate dynamics of the northern hemisphere, the role of the North Pacific in global climate over longer periods remains uncertain relative to its North Atlantic and Southern Ocean counterparts. Recent advances in proxy development and chronostratigraphic techniques, when coupled with high-resolution sedimentary archives, facilitate the first steps towards placing the variability of the North Pacific basin into a well-constrained global framework. We broadly solicit contributions of diverse paleoclimate records from the North Pacific, including but not limited to temperature, precipitation, circulation, and/or marginal ice sheet behavior. We also encourage submissions of data reviews and modeling results that evaluate temporal and behavioral relationships between the North Pacific and other regions. Studies that explore phase relationships and possible teleconnection mechanisms with the Atlantic and Southern Oceans are particularly welcome, with an eye to lessons applicable to future climate.
