Climate Change From Oxygen Isotopic Variation Of Pore Water From Sediments In Punderson Lake, Northeast Ohio, Rachel Daley, Fasong Yuan
Undergraduate Research Posters 2013
The environment in Ohio has changed over time. The hydroclimate, which is the climate of the water, shows changes from the Industrial Revolution to the present. Evidence for these changes can be found in levels of δ18O and δ2H isotopes in the layers of sediment and water in the lakes of Northeast Ohio. Mass spectrometry can be used to test the levels of δ18O and δ2H isotopes from pore water samples within sediment cores. In this study, surface soil and water samples were collected from cores in Punderson Lake at Punderson State Park in Newbury, Ohio. Pore water was extracted …

Plants are widely considered the most cost effective and environmentally friendly way to clean soils and waters contaminated with toxic metals, e.g. arsenic and mercury. We have focused our research on the uptake of arsenic and its biochemical effect on two species of fern, Spider brake fern and Christmas fern. Spider brake fern is known to be capable of accumulating significant amounts of arsenic. We wish to determine whether the levels of arsenic uptake in Christmas fern are comparable to Spider Brake fern (>1g kg-1 plant biomass) when both are grown under the same conditions. Another aim of the …
