Compilation of Holocene alkenone SST records along the North Pacific margins (including a new core Oki02 in the Okinawa Trough)

The sediment core Oki02 (26°04' N, 125°12' E, 1,612 m water depth), located in the Okinawa Trough, is used to analyze ~100-year-resolution alkenone-based sea surface temperature (SST) values during the Holocene. Together with previously published Holocene alkenone SST paleorecords on the pathways of a set of boundary currents flowing along the North Pacific margins, e.g., the Kuroshio Current, California Current, and Alaska Current, and available foraminiferal Globigerinoides ruber Mg/Ca-based SST records over the Western Pacific Warm Pool (WPWP), we are able to investigate the centennial- to multimillennial scale variations of the North Pacific Subtropical Gyre circulation throughout the Holocene.
