Summary

A multiple-proxy investigation was undertaken on two short cores (85 cm and 101 cm long) from Kepler Lake, an evaporation-insensitive, groundwater-fed marl lake in South-Central Alaska, with the goal of reconstructing climate and environmental changes in recent centuries. The proxies employed in this study include: calcite Carbon-Oxygen isotopes, organic matter (OM) Carbon-Nitrogen isotopes, and loss on ignition (LOI) analysis. An 800-year chronology for two cores was established based on four calibrated AMS 14 C dates on terrestrial macrofossils, 210 Pb analysis and core-to-core correlations using LOI results. δ18 O VPDB values of inorganic calcite range from -17.0[per thousand] to -15.7[per thousand], with the highest values occurring [...]
