Development of guidelines for using bioextraction technologies to manage nutrients in New Hampshire\u27s estuarine waters

There is growing literature on bioextraction approaches to managing nutrients in coastal waters, and it includes studies using a variety of species. Bivalve mollusks and macroalgae have received the most attention for several reasons, but perhaps foremost because of their aquaculture potential. A December 2009 workshop at the University of Connecticut, which included speakers from several countries, indicated overall that although bioextraction approaches hold substantial potential there are still many unanswered questions. The present review takes a “what we know/what we need to know” perspective, and focuses on aquaculture. For some taxa (e.g., eastern oyster), wild populations occur in New Hampshire which provide substantial nutrient bioextraction. The associated processes that result in nutrient removal from the ecosystem, however, are generally more complicated and much more difficult to unambiguously quantify except when actual harvest data are available. Therefore, the present review focuses on aquaculture, and it is restricted to those taxa (plants and animals) that occur in New Hampshire. It should be noted that the present project is associated with a recently completed project (funded by the Piscataqua Region Estuaries Partnership [PREP]) consisting of a field experiment designed to provide empirical data on nutrient uptake by oysters. The final report for this project represents the starting point for future research that will more completely characterize the bioextraction potential for oysters in New Hampshire (see discussion of Grizzle and Ward 2011 below)

Herbicide Application Rates: Risk Premiums with Environmental Implications

This paper examines the role of risk aversion in setting herbicide label rates and application rates. Companies establish label rates to be efficacious for a wide range of conditions. The use of reduced rates of herbicide offer the opportunity to increase farm profit and reduce herbicide use, an environmental benefit.Crop Production/Industries, Environmental Economics and Policy, Risk and Uncertainty,

Comparison of NAE porous wall and NASA adaptive wall test results using the NAE CAST-10 airfoil model

Wind tunnels can now simulate flows over airfoils at high Reynolds numbers and high subsonic speeds. Methods to correct for (or reduce) test section wall interference at these test conditions must be validated. The National Aeronautics Establishment (NAE) of Canada and NASA have a cooperative agreement to study this area. The NAE designed, built, and tested a CAST-10 airfoil model in its conventional Two-Dimensional High Reynolds Number Facility. The results were corrected using classical correction techniques. NASA then tested the same model in its 0.3-meter Transonic Cryogenic Tunnel with the adaptive wall test section. The adaptive wall test section reduced the wall interference to what was expected to be an acceptable level. The corrected NAE results are compared with the uncorrected NASA results. The NAE results are also compared with NASA results after residual corrections for top and bottom wall interference. Finally, a comparison of both sets of results corrected for interference from all four walls is presented
