Isotope hydrology  data from the southern Yukon indicate that the oxygen isotope composition of water  from Jellybean Lake reflects the composition of mean-annual precipitation, d18Op.  Recent changes in the d18O of Jellybean sedimentary calcite (d18Oca) correspond  to changes in the North Pacific Index (NPI), a measure of the intensity and position  of the Aleutian Low (AL) pressure system. This suggests that d18Op variability was  related to the degree of fractionation during moisture transport from the Gulf of  Alaska across the St. Elias Mountains and that Holocene shifts were controlled by  the intensity and position of the AL. Following this model, between ~7500 and 4500  cal yr B.P., long-term trends suggest a predominantly weaker and/or westward AL.  Between ~4500 and 3000 cal yr B.P. the AL shifted eastward or intensified before  shifting westward or weakening between ~3000 and 2000 cal yr B.P. Rapid shifts  eastward and/or intensification occurred ~1200 and 300 cal yr B.P. Holocene changes  in North Pacific atmospheric circulation inferred from Jellybean Lake oxygen  isotopes correspond with late Holocene glacial advances in the St. Elias Mountains,  changes in North Pacific salmon abundance, and shifts in atmospheric circulation  over the Beaufort Sea.","author":null,"citation":"Anderson, L., M.B.
