A Taxonomic Survey Of Lamp Flora (Algae And Cyanobacteria) In Electrically Lit Passages Within Mammoth Cave National Park, Kentucky, Thomas Smith, Rick Olson

International Journal of Speleology

A taxonomic survey of the lamp flora from electrically lit passages in Mammoth Cave, Mammoth Cave National Park, identified 28 species. Overall, cyanobacteria were dominant represented by 14 species (50% of the total), green algae had eight species (29%), and six diatoms species (21%) were present. There was not a correlation between species diversity and temperature, but there is a general trend of increasing diversity with warmer temperatures. There were two algal or cyanobacterial species identified in this study that overlapped with previous studies. There is a lack of continuity between previous studies only having one species identified in more …

Hydrolgeologic Groundwater Sensitivity And Vulnerability Mapping In South Central Kentucky, Andrea Croskrey

Masters Theses & Specialist Projects

Groundwater sensitivity (Ray and O'dell 1993 a) refers to the inherent ease with which groundwater can be contaminated based on hydrogeologic characteristics. We have developed digital methods for identifying areas of varying groundwater sensitivity for a ten county area of south-central Kentucky relevant to a scale of 1: 24,000. The study area includes extensive limestone karst sinkhole plains, with groundwater that is generally extremely sensitive to contamination. Digitally Vectorized Geologic Quadrangles (DVGQs) were combined with elevation data to both identify hydrogeologic groundwater sensitivity regions and to identify zones of "high risk runoff where contaminants could be transported in runoff from …

The Corn Belt Multi-State Corn Nitrogen Rate Calculator: Not Reliable For Kentucky Corn Producers, John H. Grove, Gregory J. Schwab

Soil Science News and Views

Because of the rising price of nitrogen (N) fertilizer, university personnel across the country are in the process of fine tuning N recommendations for com. Historically, each state has had different N recommendations based on research results obtained in different production systems and growing environments across each state. Some states in the Com Belt have used a yield potential (yield goal) approach to N recommendations. The expected yield is multiplied by a factor (usually 1.2) and then N credits for previous crop, manure, etc. are subtracted. One problem with this method is that as com yields increase N recommendations also …

Generalized Geologic Map For Land-Use Planning: Nelson County, Kentucky, Stephen F. Greb, Bart Davidson, Daniel I. Carey

Map and Chart--KGS

This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

Groundwater Quality In Kentucky: Barium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Barium is a silver-white alkaline earth metal that is not found free in nature because it is highly reactive with sulfate and carbonate. Barium compounds can be naturally occurring or man-made. The most common natural occurrence of barium is in the mineral barite (barium sulfate), which has many uses in industry, such as a filler in the making of rubber, plastic and resin, white pigment, drilling lubricants used in the oil and gas industry, paint, bricks and glass (Agency for Toxic Substances and Disease Registry, 2004). Barium sulfate is very slightly soluble in water and absorbs X-rays, making it an …

Chemical Analysis Of Fish Tissue: Kentucky Army National Guard Wendell H. Ford Western Kentucky Training Site, Muhlenberg County, Kentucky, Steven E. Webb, James S. Dinger, Dennis H. Cumbie

Information Circular--KGS

Thirty-one analytes were measured in fish tissue taken from largemouth bass, catfish, and bluegill harvested from lakes and ponds in reclaimed and unreclaimed coal-mine spoil of Pennsylvanian age. The spoil area is approximately 7,756 acres created primarily from surface mining, and has been used in increasing intensity since 1969 as a training site by the Kentucky Army National Guard. Four fish were harvested for analysis from the area of unreclaimed spoil that resulted from mining prior to 1977, and 15 fish were harvested for analysis from the part of the training facility that was reclaimed by 1985. Twenty-six analytes had …

Pyritized Tube Feet In A Protasterid Ophiuroid From The Upper Ordovician Of Kentucky, U.S.A., Alexander Glass

All Faculty Scholarship for the College of the Sciences

A single specimen of the protasterid ophiuroid Protasterina flexuosa from the Kope Formation (Cincinnatian, Upper Ordovician) of Kentucky exhibits three−dimensionally pyritized tube feet. This represents the first report of soft−tissue preservation in an echinoderm from the type−Cincinnatian series. The tube feet are solid and lack all internal structure. They consist of aggregated masses of small euhedral to subhedral pyrite crystals suggesting that pyritization, although decay−induced and mediated, did not necessarily replicate soft−tissues but might instead have formed inside the void−spaces left behind during the decay process. The discovery of pyritized soft−tissue as delicate as ophiuroid tube feet suggests that similar …

Groundwater Quality In Kentucky: Mercury, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Mercury is a naturally occurring metal that occurs in trace amounts in water, soils, and rocks. Elemental mercury is a liquid that occurs in some ore deposits; it may also be concentrated around hot springs. Currently, about 50 percent of mercury use is for electrical products such as dry-cell batteries, fluorescent lights, switches, and other control equipment. Mercury is also used in the electrolytic preparation of chlorine gas and caustic soda, and in paint manufacture and pesticide production (U.S. Environmental Protection Agency, 2002). In the past, significant amounts of mercury were used in thermometers and pressure gauges.

Groundwater Quality In Kentucky: Selenium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Selenium is a naturally occurring element found in most rocks and soils (Agency for Toxic Substances and Disease Registry, 2003). In its solid form, selenium is black, gray, or red and is odorless (New Jersey Department of Health and Senior Services, 2002). Most selenium is obtained from byproducts of the copper refining industry. Selenium compounds are often used in electronic components, photocopiers, metal alloys, rubber, paint pigments, glass-making (ruby red glass), and photographic emulsions (U.S. Environmental Protection Agency, 2003). Selenium exhibits both photovoltaic and photoconductive properties. As more light shines on selenium, its electrical conductivity increases, making it extremely useful …

Lithostratigraphy Of Precambrian And Paleozoic Rocks Along Structural Cross Section Ky-1, Crittenden County To Lincoln County, Kentucky, Martin C. Noger, James A. Drahovzal

Report of Investigations--KGS

This east–west cross section across western Kentucky is one of a network of regional cross sections prepared by the Illinois Basin Consortium that illustrate the structural and stratigraphic framework of the Illinois Basin. The structural cross section uses wireline logs of deep tests, as well as proprietary reflection seismic data, to show the relationship of Paleozoic rocks to each other from the surface to the top of the Precambrian unconformity.

The line of the cross section extends east from the complexly faulted Western Kentucky Fluorspar District across the Moorman Syncline and the underlying Rough Creek Graben to the Cincinnati Arch …

Groundwater Quality In Kentucky: Cadmium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Cadmium is a metallic element that occurs naturally in the earth's crust, especially in zinc-, lead-, and copper-bearing ores (Forstner and Whittmann, 1981). Pure cadmium is a soft silver-white metal, but is rarely found naturally in its pure form. It is commonly combined with other elements, such as oxygen (cadmium oxide) and sulfur (cadmium sulfate).
