Paleoclimate, paleoventilation, and paleomagnetism as recorded in a 17kyr marine sediment record from the SE Alaska margin
Oregon State University, Eugene
The deglacial behavior of the sub-Arctic North Pacific is poorly constrained, with many published records suffering from limited age control due to extensive post-depositional carbonate dissolution. Alternative dating methods include the correlation of stable-isotopic and/or paleomagnetic secular variation (PSV) records to an independently-dated regional template, however no such template currently exists. Core EW0408-85JC (59Â°33.32'N, 144Â°9.21'W, 682 m water depth) is located above the carbonate compensation depth on the Gulf of Alaska margin, affording an opportunity to inter-compare stable-isotopic and paleomagnetic variability from a single location, as well as place these observations in a global context via an independent radiocarbon-based chronology.
