attribute NC_GLOBAL acquisition_description String Methodology:  \n Dissolved inorganic carbon concentration ([DIC]) samples were measured by\nacidification and subsequent release of CO2 with a CO2 cavity-ringdown\nspectrometer (CRDS; Picarro G1101-i) detector to an accuracy and precision\nbetter than \\u00b1 3 umol/kg. Precision is based on a set of 15 duplicates.\nAccuracy is based on certified reference materials prepared at the Scripps\nInstitution of Oceanography of the University of California, San Diego.\n \nSamples for pH were measured spectrophotometrically on board using an Agilent\nCary 100 UV-Visible spectrophotometer and m-cresol purple dye (Clayton and\nByrne, 1993; Liu et al., 2011). The pH values are reported on the total scale\nwith a precision better than 0.0002 based on duplicate measurements. The\nestimated accuracy of spectrophotometric pH is better than 0.002.\n \nNatural radiocarbon samples of DIC (\\u220614C-DIC) were analyzed at the W. M.\nKeck Carbon Cycle Accelerator Mass Spectrometry Laboratory at the University\nof California, Irvine. The accuracy and precision of the \\u220614C-DIC\nmeasurements is 0.1\\u2030 and 1.7\\u2030, respectively.\n \nSampling and analytical procedures:\\u00a0  \n Discrete seawater samples were collected inside Hudson Canyon, US Atlantic\nMargin aboard the R/V Endeavor from 9 - 13 of July 2014. A total 19 stations\nand 216 samples were collected along Hudson Canyon and another station was\nsampled outside the canyon (station E2-HC2). Samples were collected from a\nbottle Rosette following the procedures in SOP 1 and 6b in Dickson et al.,\n(2007).\n \n[DIC] samples were collected in acid washed and combusted 120 mL serum vials.\nVials were allowed to overflow three times their volume, poisoned with 50 uL\nof a 55 uM HgCl2, capped, and store at 4 degrees C\\u00a0until analysis.\n \n\\u220614C-DIC samples were collected in combusted 1L borosilicate bottles,\npoisoned with 200 uL of a 55 uM HgCl2, sealed and stored in the dark at room\ntemperature until isotope analysis.\n \nCH4 concentration analyses were collected by filling 60, 120, or 160 mL glass\nserum vials. Vials were filled from the bottom with a length of 1/4\\\" Tygon\ntubing. Vials were flushed with seven vial volumes of seawater to expel any\nbubbles and ensure collection of a clean sample, and then were sealed with\nbutyl rubber stoppers taking care not to introduce bubbles during sealing.\nImmediately after sealing, a 10 mL headspace of ultrahigh purity nitrogen was\nintroduced, displacing an equal volume of water, and the samples were\npreserved by adding 25 uL of a saturated solution of mercuric chloride. The\nvials were stored inverted to minimize diffusive gas exchange through the\nbutyl rubber stopper.\n \nCH4 concentration measurements were performed using an Agilent 6850 gas\nchromatograph with a flame ionization detector (GC-FID) following established\nprotocols reported in Weinstein et al. (2016). The uncertainty associated with\nthese measurements was 5.2% based on duplicate measurements.

attribute NC_GLOBAL projects_0_acronym String Aerobic methane oxidation
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nRoughly 8 billion moles of methane (CH4) were emitted in 83 days during the Deepwater Horizon disaster in the northern Gulf of Mexico in 2010. Interestingly, none of this CH4 was emitted to the atmosphere, but instead stayed dissolved and suspended as \"plume\" or \"intrusion\" layers approximately 1000m below the ocean surface. Based on measurements of CH4 concentration and oxidation rates, dissolved oxygen anomalies, and microbial community structure as well as a CH4 geochemical model, it was determined that all the CH4 emitted during this disaster was respired within 120 days of the initial well blowout. In addition, the methanotrophic bacteria responsible for the oxidation of this CH4 appeared to experience all stages of microbial growth, limited only by the availability of CH4. This finding suggests that releases of CH4 into deepwater, be them anthropogenic or natural, will have minimal direct influence on the radiative budget of the atmosphere.\nThe major weakness in these previous investigations is that CH4 related parameters were only measured at the beginning (May - June 2010) and end (September - October 2010) of this massive CH4 feast, primarily because the rapid demise of CH4 was unanticipated. Thus, the time- and growth phase-dependent understanding of the kinetics of this bloom response is only based on model interpolation between endpoints. A more complete, and measurement-based, understanding of the chemical kinetics is necessary to predict an oceanographic environment's ability to respire large CH4 perturbations. And while measurements of CH4 stable isotopes in theory can be used to assess the extent that the released CH4 has been oxidized, this kinetic isotope effect can only be used in a quantitative fashion if it is known how the isotopic fractionation factor changes with varying chemical and temperature conditions and throughout all stages of the microbial bloom.\nIn this study, researchers at the Texas A & M University will test two fundamental hypotheses relating to aerobic CH4 oxidation and ultimately produce a thorough characterization of the time-, growth phase-, and temperature-dependency of CH4 oxidation rates, oxidation rate constants, and isotopic fractionation factors. Hypothesis 1: Excluding mixing processes, the bacterial response to a large CH4 perturbation will be limited primarily by the availability of CH4 or dissolved oxygen. Hypothesis 2: Without knowing the stage of microbial growth, measurements of natural stable isotopes of CH4 and dissolved carbon (organic and/or inorganic) cannot be used to assess the extent of CH4 oxidation in situations of large CH4 perturbations. In order to test these hypotheses, with the goal of disproving hypothesis 2, a suite of mesocosm and pure culture incubations will be conducted. Throughout these incubations, concentrations of CH4 and dissolved inorganic carbon as well as their 13C isotopes will be measured in extremely high resolution with new equipment and experimental designs. In addition, dissolved oxygen, nutrient concentrations, trace metals, CH4 oxidation rates, and microbial community structure will be measured.\nBroader Impacts. In addition to the normal dissemination of results in publications, meeting presentations, and on a project web site, this work will have strong educational and research impacts with close interactions between the PIs, postdoctoral scholar, graduate student, and undergraduate researchers with collaborations between Texas A&M University and the University of California Santa Barbara. The students will have extended visits at each lab for skill development, knowledge transfer, and general academic growth. During 2010, an informal collaboration was established with Ms. Vicki Soutar, a high school science teacher in Watkinsville, GA, to develop high school science laboratory exercises using real scientific data. This proposed project will involve Ms. Soutar to formalize, enhance, extend, and disseminate the products of this collaboration
