The Geological Sciences Colloquium Series presents Ryan Wolbert and Ian Forsythe, Geological Sciences graduate students discussing their research on Nov. 1 at 2 p.m. in Clippinger 205.

Albright presents “Effective remediation approach for improving acid mine drainage conditions using slow release hydrogen peroxide systems.”

Abstract: This discussion will focus on the potential effectiveness of using slow release hydrogen peroxide forms to treat areas impacted by acid mine drainage, assessed through preliminary laboratory and field results. Findings stem from qualitative procedures and quantitative methods resulting in H2O2 concentration curves of values that are known, as well as measured values assessed through column testing for the duration of approximately 2-3 weeks. Field results include initial site characteristics such as water chemistry and heavy metal concentrations, and comparison of sample site characteristics (prior to form placement) to times tested after form placement in Brush Fork stream.

Forsythe presents “Delineating Species of Rafinesqina in the Type Cincinnatian: A Morphometric Approach.”

Abstract: The Cincinnati Ohio region is home to exceptional deposits of shallow marine fossils. These strata have been studied scientifically since the early 1800s and in that time many species have been named. The brachiopod genus Rafinesquina is among the most common fossils found in these rocks and contains multiple named species.  However, the species within this genus were erected using an outdated typological species concept. In this analysis a morphological species concept is employed to reanalyze the genus using modern methods. Two analyses were conducted: A geometric morphometric analysis, and a character based morphometric analysis. The results of these analyses not only provide further support for the efficacy of morphometrics as a method of species delineation, but function as a framework with which a comprehensive revision of the genus can be conducted.
