| Fine-scale, paired Mg/Ca-O-18 profiles (Globigerinoides ruber white, sensu lato) from the San Lazaro Basin (SLB) at 25 degrees N in the Northeast Pacific reveal a transition from a predominant presence of tropical/subtropical waters during the last glacial termination (T1) to an increasing influence of fresh and cold California Current waters toward the Holocene. Changing atmospheric circulation patterns over the Northeast Pacific in step with the demise of the Northern Hemisphere ice sheets and/or with a shift from El Nino- to La Nina-like conditions toward the Holocene are prime candidates to explain this water mass change. O-18(SW-IVC) increases of similar to 0.5-0.7 during the Younger Dryas (YD) and Heinrich stadial 1 (HS1) at the SLB are observed in a... |
