Cave air and dripwater variability in Cathedral Caverns, Alabama
Monthly monitoring of dripwater (δ18O, δD, [DIC], δ13CDIC, and pH) and air (pCO2 and δ13CCO2) chemistry from within Cathedral Caverns (Grant, AL) was conducted for 12 months (January 2015-December 2015) to better characterize the factors influencing deposition and δ18O chemistry of speleothems …

Addressing Water Resource Issues In Barbados Through An Isotopic and Atmospheric Characterization of Precipitation Variability
… have analyzed isotopic variation of meteoric and dripwater in karst environments for paleoclimate reconstructions or aquifer recharge capacity. What is poorly understood is how the isotopic signal of δ<sup>18</sup>O and δ<sup>2</sup>H is transferred through the hydrologic cycle based upon storm …

Physical and geochemical response in cave drip waters to recent drought, central Texas, USA : implications for drought reconstruction using speleothems
… drought. Drip rate, calcite growth rate, and dripwater geochemistry were monitored before, during, and after the peak of a record-breaking drought in central Texas that began and peaked in 2011, and which continued through to early 2015. Three groups of drip sites are identified based on …

The terrestrial carbon cycle in transition: tracking changes using novel tracers on multiple timescales
… calcite samples. A case study of flowstones and dripwaters from three New Zealand caves was also conducted. In the case study, 3D EEM fluorescence-inferred DOC concentrations were measured in the dripwaters and speleothems, thus enabling calculation of DOC partition coefficients between …

Organic complexation in karst cave systems: implications for transition metal incorporation into speleothems
… availability (by example of Co, Ni, Cu) at the dripwater-speleothem interface, whereas alkaline earth metals (here: Mg, Sr) are essentially unaffected by organic interactions in solution. OMC stability was found to occur in the hierarchy of Cu ≈ Co > Ni, with a variable fraction of all three …
