Collaborative Research: Cryptic nitrogen cycling in the anoxic subterranean estuary https://osprey.bco-dmo.org/project/805722 Collaborative Research: Cryptic nitrogen cycling in the anoxic subterranean estuary <p><em>NSF Award Abstract:</em><br /> Nitrogen is an important nutrient that maintains high coastal ecosystem productivity. Yet excess nitrogen delivery can cause serious water quality deterioration including harmful algal blooms, fish kills, and oxygen free dead zones. Numerous nitrogen transformations regulate the balance between nitrogen delivery and nitrogen removal in coastal environments and the majority of these reactions occur in sediments where seawater passes through the subsurface and mixes with groundwater transported from uplands. This mixing zone, referred to as the subterranean estuary, is characterized by very different geochemistry than either the seawater above it or the groundwater below it. Thus, it has the potential to host a variety of unique reactions that affect nitrogen availability to the overlying water. Scientists from the College of William and Mary, Virginia Institute of Marine Science (VIMS), and the University of Connecticut (UConn) propose to examine the importance of a cryptic nitrogen cycle, a novel and potentially widespread nitrogen cycling process in the subterranean estuary. The cryptic nitrogen cycle comprises anoxic ammonium oxidation to nitrite (anoxic nitrification) coupled with anaerobic ammonium oxidation (anammox) or denitrification producing harmless dinitrogen gas. The proposed project represents highly transformative science because it has the potential to change the current paradigm detailing operation of the biogeochemical nitrogen cycle in anoxic environments. Occurrence of the cryptic nitrogen cycle would have broad implications for the nitrogen budget of terrestrial and groundwater systems and the coastal ocean. Characterization of the cryptic nitrogen cycle will allow us to better understand interactions among the nitrogen, metals, and sulfur cycles, and potential impacts of ongoing human modification of coastal environments. Educational contribution of this project focuses on graduate and undergraduate student training. Two graduate students at VIMS and UConn will receive interdisciplinary training in microbiology, molecular ecology, and biogeochemistry while several undergraduates recruited through the VIMS REU (Research Experience for Undergraduates) Program and the UConn marine science programs will also participate in the project. In addition, three summer undergraduate interns will be recruited from Hampton University, a historically Black college, and trained to enhance minority education and research in marine science. Public outreach will be achieved through popular venues such as VIMS Marine Science Day, and the VIMS After Hours Public Lecture Series at VIMS. Tobias at UConn also provides educational contributions and outreach efforts through the UConn Marine Scholars and Early College Experience programs and an exhibit at Mystic Aquarium.</p> <p>A cryptic nitrogen cycle is proposed as a new process coupling anoxic nitrification to microbial nitrogen removal pathways such as anammox and denitrification. Unlike anammox, which refers to the oxidation of ammonium by nitrite to form dinitrogen (N2) gas, anoxic nitrification occurs by oxidation of ammonium in the absence of oxygen using other common chemical oxidants such as metal oxides (namely, Fe and Mn) or sulfate, abundant in many marine and coastal systems. The thermodynamic favorability of these reactions relies on coupling nitrite formed via these oxidants with anammox or denitrification. Due to the coupling, nitrite will not accumulate or be measurable in anoxic marine systems. Thus, a cryptic N cycle responsible for nitrite production can occur as a novel N transforming process in anoxic environments, serve as a vital link to N2 production, and attenuate N loads discharging from a subterranean estuary (STE). Preliminary results from a STE in the York River Estuary located in Virginia showed substantial N2 production, representing removal of 50-75% of the fixed groundwater N, in ferruginous and sulfidic zones where neither nitrite nor nitrate were detectable. Stable isotope incubation experiments using the 15N tracer and molecular analysis of microbial communities suggest that coupled anoxic nitrification and anammox processes are the dominant N2 production pathways rather than canonical denitrification in the STE. Therefore, coupled anoxic nitrification-anammox in coastal groundwater may be a major unrecognized sink for fixed nitrogen at the land-sea interface. In addition to coastal groundwater, the cryptic N cycle has potential importance in anoxic zones and ocean basins. This proposal focuses on the STE because geochemical conditions there appear optimal for the proposed reactions to occur, and our preliminary data show strong evidence for a cryptic N cycle. The proposed work uses a combined geochemical, 15N isotope tracer and microbiological approach to evaluate environmental controls on the cryptic N cycle as well as to estimate its contribution to reduction of fixed N fluxes to the coastal ocean. Four approaches are proposed: (1) Field characterization of anoxic nitrification reactions and associated microbial communities in a subterranean estuary; (2) Laboratory incubation experiments to identify hotspots of the cryptic N cycle; (3) Controlled microcosm experiments to determine geochemical controls on anoxic nitrification; and (4) in situ assessment of anoxic nitrification to estimate the importance of the cryptic N cycle in a coastal aquifer.</p> Subsurface cryptic N cycle largerWorkCitation project eng; USA oceans -76.5053 -76.5053 37.248884 37.248884 2021-05-11 2021-05-11 Temperate (Mid-Atlantic), Sandy Beach along the York River Estuary, Gloucester Point, Virginia, USA (37.24884N/76.505324W) 0 BCO-DMO catalogue of parameters from Water level data from a slug test within a shallow, sandy subterranean estuary (STE), Gloucester Point, Virginia USA in May 2021 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/894455.rdf Name: Latitude Units: decimal degrees Description: <p>Latitude of well location</p> http://lod.bco-dmo.org/id/dataset-parameter/894456.rdf Name: Longitude Units: decimal degrees Description: <p>Longitude of well location</p> http://lod.bco-dmo.org/id/dataset-parameter/894457.rdf Name: Date_Time Units: unitless Description: <p>Date and time of measurement (GMT-04:00)</p> http://lod.bco-dmo.org/id/dataset-parameter/894458.rdf Name: Abs_Pres Units: kilopascals Description: <p>Pressure measured by pressure transducer</p> http://lod.bco-dmo.org/id/dataset-parameter/894459.rdf Name: Temp Units: celsius Description: <p>Temperature measured by pressure transducer</p> http://lod.bco-dmo.org/id/dataset-parameter/894460.rdf Name: Water_Level Units: meters Description: <p>Water level determined by pressure and manual calibration at sensor deployment</p> http://lod.bco-dmo.org/id/dataset-parameter/894461.rdf Name: Time_after_slug_addition Units: unitless Description: <p>Number of seconds after adding test water slug</p> http://lod.bco-dmo.org/id/dataset-parameter/894462.rdf Name: Drawdown Units: meters Description: <p>Drawdown in water level over time</p> http://lod.bco-dmo.org/id/dataset-parameter/894463.rdf Name: Normalized_drawdown Units: unitless Description: <p>Drawdown divided by the initial change in volume due to slug</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 53223 https://darchive.mblwhoilibrary.org/server/api/core/bitstreams/4774088c-3e7d-4d4f-ae11-48e00f822c30/content download https://doi.org/10.26008/1912/bco-dmo.894312.1 download onLine dataset &lt;p&gt;These water level data were collected during 2021 from a sandy subterranean estuary (STE) located in Gloucester Point, Virginia, USA.
