Summary
Abstract: Carbon and oxygen isotopic trends from seven Midwestern speleothems record
significant offsets in the timing of middle-Holocene vegetation change.
Interactions of dry Pacific and moist Gulf of Mexico air masses maintained a
sharp moisture gradient across Iowa, Minnesota, and Wisconsin such that the
arrival of prairie was offset by 2000 years between caves and pollen sites
located only 50 km apart. Oxygen isotopes shift concomitantly with carbon in
most cases, although these changes are believed to represent increased
evaporative enrichment of 18O prior to infiltration during the prairie period.
