H.\n(2015), Habitat context influences nitrogen removal by restored oyster reefs.\nJ Appl Ecol, 52: 716\\u2013725.\ndoi:[10.1111/1365-2664.12435](\\\\\"https://onlinelibrary.wiley.com/doi/10.1111/1365-2664.12435/abstract\\\\\")\n \nSediment cores (contained in 6\\u00b74-cm-diameter by 17-cm-long polycarbonate\ntubes, 10\\u00a0cm depth) were collected adjacent to each reef habitat\n(n\\u00a0=\\u00a03) and control habitat (without reefs,\\u00a0n\\u00a0=\\u00a03) in\neach context at low tide on 28 June 2010. Cores collected from oyster reefs\ndid not contain live oysters. Additionally, ~100\\u00a0L of water was collected\nfor use in the laboratory incubations. Following collection, sediment cores\nand water were transported to an environmental chamber (Bally, Inc., Morehead\nCity, NC, USA) at The University of North Carolina Institute of Marine\nSciences in Morehead City, NC. Surface water measurements of dissolved O2,\nsalinity and water temperature (YSI 600 Series Sonde and Model 650 data\nlogger; Yellow Springs Instruments, Yellow Springs, OH, USA) were also\ncollected. Oyster density in the reef was determined by placing a\n0\\u00b725-m2\\u00a0quadrat\\u00a0on each reef (one\\u00a0quadrat\\u00a0per reef)\nand counting all the oysters present with a shell length >25\\u00a0mm\n(Powers\\u00a0et\\u00a0al.\\u00a02009).

attribute NC_GLOBAL project String Oyster Reef N2O Emission
attribute NC_GLOBAL projects_0_acronym String Oyster Reef N2O Emission
attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:\nOyster reefs are biogeochemical hot spots and prominent estuarine habitats that provide disproportionate ecological function. Suspension-feeding eastern oysters, Crassostrea virginica, are capable of improving water quality and diminishing eutrophication by filtering nutrients and particles from the water and depositing them in the sediments. Remineralization of these deposits may enhance sedimentary denitrification that facilitates nitrogen removal in tidal estuaries. However, the scientific underpinning of oyster reef function has been challenged in various studies. In addition, recent studies of filter feeding invertebrates reported the production of nitrous oxide (N2O), a greenhouse gas, as an end product of incomplete denitrification by gut microbes. C. virginica could be another source of N2O flux from intertidal habitats. Preliminary work indicated substantial N2O production from individual oysters. The estimated N2O production from high density oyster reefs may exceed the N2O flux measured from some estuaries. With the new discovery of N2O emission and uncertainty regarding eutrophication control, the ecological value of oyster reef restoration may become equivocal.\nThis project will quantify N2O fluxes to understand the factors controlling N2O emission from oyster reefs. Sedimentary N processes will be examined to develop an oyster reef N model to estimate N2O emission from tidal creek estuaries relative to other N cycling processes. The PIs hypothesize that intertidal oyster reefs are a substantial source of N2O emission from estuarine ecosystems and the magnitude of emission may be linked to water quality. If substantial N2O flux from oyster reefs is validated, ecological benefits of oyster reef restoration should be reevaluated. This interdisciplinary research team includes a microbial ecologist, a biogeochemist, an ecologist and an ecosystem modeler. They will utilize stable isotope and molecular microbiological techniques to quantify oyster N2O production, elucidate microbial sources of N2O emission from oysters and sediments, and estimate seasonal variation of N2O fluxes from oyster reefs. Measurements from this study will be integrated into a coupled oyster bioenergetics-sediment biogeochemistry model to compare system level rates of N cycling on oyster reefs as a function of oyster density and water quality. Modeling results will be used to assess the relative trade-­offs of oyster restoration associated with N cycling. They expect to deliver the following end products:1) estimation of annual N2O flux from oyster reefs as an additional source of greenhouse gases from estuaries, 2) a better understanding of the environmental and microbial factors influencing N2O and N2 fluxes in tidal estuaries, 3) transformative knowledge for the effect of oyster restoration on water quality enhancement and ecosystem function, 4) direct guidance for oyster restoration projects whose goals include water quality enhancement, and 5) a modeling tool for use in research and restoration planning.
