Age determinations on sediment core PS1295-4 (Table 1), supplement to: Jones, Glenn A; Keigwin, Lloyd D (1988): Evidence from Fram Strait (78°N) for early deglaciation. Nature, 336(6194), 56-59

Glenn A Jones & Lloyd D Keigwin
Recent syntheses of the history of the last Northern Hemisphere glaciation and deglaciation illustrate that understanding of the mechanisms and timing of deglaciation before approximately 12,000 years BP is limited. After 12,000 yr BP, however, there is sufficient evidence from radiocarbon-dated morains, raised beaches, varved lake sediments and pollen records to provide a reasonable temporal and geographica picture of the decay of the ice sheets. Here we report on the first oxygen isotope record from...
