Latest Quaternary Paleoclimate Reconstruction Utilizing Stable Isotopic And Trace Element Proxies In A Stalagmite From Culverson Creek Cave, West Virginia, Ashley Nicole Gilbert
Latest Quaternary Paleoclimate Reconstruction Utilizing Stable Isotopic And Trace Element Proxies In A Stalagmite From Culverson Creek Cave, West Virginia, Ashley Nicole Gilbert
University of Kentucky Master's Theses
A reconstruction of regional climate variability in southern West Virginia that spans the last glacial/interglacial transition is presented. Paleoclimate interpretations obtained from the 50-cm long stalagmite provide key insights regarding the timing, magnitude, and forcing mechanisms responsible for past climate variability. Stable isotopic (δ18O and δ13C) and trace element (Ba, Sr, Mg) signatures from samples contiguously milled along the growth-axis of a 230Th-dated stalagmite which grew between approximately 20 and 5 thousand years before present (kyr BP) provide critical constraints for above-cave mean annual temperature, seasonality of moisture mean annual precipitation, and potential vegetation shifts. …
