A Quantitative Analysis Of Interstitial Fluid-Chemistry And Limestone Dissolution Rates Within The Clastic Sediment Of A Karst Aquifer Conduit, Mammoth Cave, Kentucky, Kevin Vaughan
Masters Theses & Specialist Projects
Many active stream conduits within karst aquifers transport and deposit non-carbonate, clastic sediment. However, little is known about how these sediments impact conduit development and enlargement rates. For example, can dissolution take place at the sediment/bedrock interface beneath a flowing stream? If not, cavern enlargement might be dominated by flood conditions when the bare rock of the walls and ceiling are in contact with the dissolving fluids. An approach using limestone tablet weight loss experiments, along with water sampling and geochemical modeling, has been undertaken to understand the nature of fluid movement and chemistry with the sediment beneath an active …

Seasonal Effects On The Geochemical Evolution Of The Logsdon River, Mammoth Cave, Kentucky, Darlene Anthony
Seasonal Effects On The Geochemical Evolution Of The Logsdon River, Mammoth Cave, Kentucky, Darlene Anthony
Masters Theses & Specialist Projects
The following research describes the collection and evaluation of geochemical data from the Logsdon River, an open-flow conduit that drains a portion of the Turnhole Spring drainage basin within the Mammoth Cave karst aquifer of south-central Kentucky. This spatial survey of nearly 10 km of continuous base-level conduit included seasonal sampling of carbon dioxide partial pressures (Pco2)> dissolved ions, and saturation indices for calcite (SIcal). The highest PC02 values are found at the upstream site, closest to the Sinkhole Plain recharge area, which creates under-saturated conditions. Rapid outgassing of C02 into the cave atmosphere creates oversaturated conditions for several thousand …
Measuring The Applicability Of The Seville Strategy To The Mammoth Cave Area Biosphere Reserve, Debra Kreitzer
Measuring The Applicability Of The Seville Strategy To The Mammoth Cave Area Biosphere Reserve, Debra Kreitzer
Masters Theses & Specialist Projects
The dominant paradigms of the past decade involve the preservation of biodiversity through the use of landscape corridors and buffer zones, as well as the integration of economic growth through sustainable use. The International Biosphere Reserve (IBR) program, as defined in the Seville Strategy, encourages locations already involved in conservation to continue to protect biodiversity and foster harmonious relationships between humans and their environment through sustainable development. An excellent example of an IBR is the Mammoth Cave Area Biosphere Reserve (MCABR) in south-central Kentucky. In order to measure the significance of the implementation of the Seville Strategy in the MCABR, …
