Stalagmites BCC-2, BCC-4, and BCC-6 were collected >1 km from the cave entrance and ~35 m below the surface. Oxygen isotope samples were milled at 1-mm intervals, with results reported in per mil V-PDB. Data notes: Uranium and thorium isotopic compositions and 230Th ages by ICP-MS Analytical errors are 2s of the mean. *a d234U = ([234U/238U]activity - 1) x 1000. *b d234Uinitial corrected was calculated based on 230Th age (T), i.e., d234Uinitial = d234Umeasured X el234*T, and T is corrected age. *c [230Th/238U]activity = 1 - e-l230T + (d234Umeasured/1000)[l230/(l230 - l234)](1 - e-(l230 - l234) T), where T is the age. Decay constants are 9.1577 x 10-6 yr-1 for 230Th, 2.8263 x 10-6 yr-1 for 234U, and 1.55125 x 10-10 yr-1 for 238U (Cheng et al., 2000). *d The degree of detrital 230Th contamination is indicated by the [230Th/232Th] atomic ratio instead of the activity ratio. *e Age corrections were calculated using an average crustal 230Th/232Th atomic ratio of 4.4 x 10-6 ± 2.2 x 10-6. Those are the values for a material at secular equilibrium, with the crustal 232Th/238U value of 3.8. The errors are arbitrarily assumed to be 50%. ABSTRACT SUPPLIED BY ORIGINATOR: We present a replicated record of Holocene climate change from a cave in West Virginia, USA. Based on analysis of stable isotopes in precipitation (d18Ow) from the closest Global Network of Isotopes in Precipitation (GNIP) station in Coshocton, OH, we interpret enriched oxygen isotopes in calcite (d18Oc) as representing an increase in the relative contribution of summer precipitation to annual totals. Significant coherence between local summer (July and August) precipitation and the Summer North Atlantic Oscillation (SNAO) index on multi-decadal timescales suggests that summer precipitation in our study area is strongly influenced by changes in the Bermuda High. A strengthened Bermuda High circulation would increase summer precipitation amounts in the region and lead to enriched d18Oc of speleothem calcite. Our d18Oc record achieves maximum values during the mid-Holocene, consistent with previous studies indicating an intensified Bermuda High circulation at that time. At 4.2 ka, d18Oc transitions to lower values at a time when numerous records around the globe document significant changes in the hydrologic budget. Over the last 2000 years, there are intervals of substantially decreased d18Oc, coincident with aridity in the Yucatan, Alpine glacial advances, and a weakened Asian summer monsoon.
