Introduction, Tor Hundloe

Tor Hundloe

ExtractAsk people to think of a catchment and they tend to think of large geographical areas and extensive communities, for example the Nile River and all the people who work on and around it and benefit from it. As the Nile catchment illustrates, many large catchments extend beyond the boundaries of one nation. For some of the world’s largest river basins, not just two, but many more countries can have some or all of their territory in the basin. National boundaries dissect catchments. A variety of different land uses and human occupations make diversity the norm of catchment economies and …

Tor Hundloe

Extract We have come to understand the human-environment dynamics of a small Tasmanian catchment. Our focus throughout the extended period we spent in the field (and sitting in front of computer screens) was to explore the relationships between the use of water by farmers and the needs of oyster growers. The relationship between upstream catchment activities and the quality and quantity of water downstream (in estuaries and off-shore lagoons) is the fundamental issue in catchment management. It necessitates an analysis of the value of water in different, and often competing, uses. On the face of it, that might seem a …

Network Technologies Used To Aggregate Environmental Data, Paul Stasiuk, Konstantin Läufer, George K. Thiruvathukal

George K. Thiruvathukal

The goal of the Loyola Weather Service (lws) project is to design and build a system of functioning environmental monitoring widgets that can intelligently and autonomously control the environment around them based on set thresholds and triggers. The widgets will also have the ability to aggregate their data and easily display this data in various ways: through a user interface in the room that the widget is placed, via a web application, and programmatically via a RESTful web service.

Uptake And Retention Of Mirex By Fish Maintained On Formulated And Natural Diets In Lake Ontario Waters, Joseph Makarewicz, Joseph Buttner, Theodore Lewis

Joseph C Makarewicz

Fish with no detectable levels of the contaminant mirex were grown in Lake Ontario waters under conditions simulating commercial aquaculture. Benthic black bullheads (Ameiurus me/as) were grown in cages placed in a bay of the lake. Pelagic rainbow trout (Oncorhynchus mykiss) were grown in terrestrial raceways served with Lake Ontario waters. Contaminant-free fingerlings were reared to a large size on a commercial ration in these systems, which partially isolated them from the contaminant-laden food web and bottom sediments. Black bullheads fed a mirex-spiked, commercially prepared food had mirex concentrations that exceeded the U.S. Food and Drug Administration (FDA) action level …

Enhanced Performance Of A Microbial Fuel Cell Using Cnt/Mno2 Nanocomposites As A Bioanode Materials, S. Kalathil, A Hoa, J Shim, Mohammad Mansoob Khan Dr, J Lee, M H. Cho

Dr. Mohammad Mansoob Khan

The anode electrode material is a crucial factor for the overall performance of a microbial fuel cell (MFC). In this study, a plain carbon paper modified with the CNT/MnO 2 nanocomposite was used as the anode for the MFC and a mixed culture inoculum was used as the biocatalyst. The modified anode showed better electrochemical performance than that of plain carbon paper, and Brunauer Emmett Teller (BET) analysis showed the high surface area (94.6 m2/g) of the composite. The Mn4+ in the nanocomposite may enhance the electron transfer between the microorganisms and the anode material which facilitates electron conduction. Additionally, …

Evaluation Of Beach Nourishment Evolution Models Using Data From Two South Carolina Beaches: Folly Beach And Hunting Island, Sc, Usa, Harry Weathers, George Voulgaris

George Voulgaris

Beach nourishment is a common method used for mitigating coastal erosion. However, it is also a costly undertaking and requires an appropriate cost-to-benefit analysis. Although the costs can be estimated relatively easily, the benefits are directly related to the life expectancy of the proposed project. With this in mind, three existing beach replenishment time-evolution models (the Linear Erosion, the Verhagen, and the One-Line models) were compared for their ability to represent data from two beach nourishment projects that have taken place in South Carolina, USA, at Folly Beach and Hunting Island. Another newly introduced model that combines the One-Line model …
