Data report: diatom and foraminiferal assemblages in Pleistocene turbidite sediments from the Cascadia margin (IODP Expedition 311), northeast Pacific1
Diatom and foraminiferal analyses of the Pleistocene turbidites in the Cascadia margin suggest that turbidite sediments originated mainly in the landward shelf area and were displaced to the present deep-sea site, which maintained a constant depth during this time. Abundant and highly fluctuating occurrences of shallow-marine and nonmarine diatoms may reflect the global glacioeustatic sea level changes in the Pleistocene.
