On flames established with air jet in cross flow of fuel-rich combustion products

Creator:: Katta, Viswanath R., Blunck, David L., Jiang, Naibo, Lynch, Amy, Gord, James R., and Roy, Sukesh
Abstract:: Advances in combustor technologies are driving aircraft gas turbine engines to operate at higher pressures, temperatures and equivalence ratios. A viable approach for protecting the combustor from the high-temperature environment is to inject air through the holes drilled on the surfaces. However, it is possible that the air intended for...

Global climate evolution during the last deglaciation

Creator:: Clark, Peter U., Shakun, Jeremy D., Baker, Paul A., Bartlein, Patrick J., Brewer, Simon, Brook, Edward J., Carlson, Anders E., Cheng, Hai, Kaufman, Darrell S., Liu, Zhengyu, Marchitto, Thomas M., Mix, Alan C., Morrill, Carrie, Otto-Bliesner, Bette L., Pahnke, Katharina, Russell, James M., Whitlock, Cathy, Adkins, Jess F., Blois, Jessica L., Clark, Jorie, Colman, Steven M., Curry, William B., Flower, Ben P., He, Feng, Johnson, Thomas C., Lynch-Stieglitz, Jean, Markgraf, Vera, McManus, Jerry, Mitrovica, Jerry X., Moreno, Patricio I., and Williams, John W.
Abstract:: Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of...

Constraints on the Late Holocene Anthropogenic Contribution to the Atmospheric Methane Budget

Creator:: Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd
Abstract:: The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Metabolism of Nonesterified and Esterified Hydroxycinnamic Acids in Red Wines by Brettanomyces bruxellensis

Creator:: Schopp, Lauren M., Lee, Jungmin, Osborne, James P., Chescheir, Stuart C., and Edwards, Charles G.
Abstract:: While Brettanomyces can metabolize nonesterified hydroxycinnamic acids found in grape musts/wines (caffeic, p-coumaric, and ferulic acids), it was not known whether this yeast could utilize the corresponding tartaric acid esters (caftaric, p-coutaric, and fertaric acids, respectively). Red wines from Washington and Oregon were inoculated with B. bruxellensis, while hydroxycinnamic acids...

Addressing ecological effects of radiation on populations and ecosystems to improve protection of the environment against radiation: Agreed statements from a Consensus Symposium

Creator:: Bréchignac, François, Oughton, Deborah, Mays, Claire, Barnthouse, Lawrence, Beasley, James C., Bonisoli-Alquati, Andrea, Bradshaw, Clare, Brown, Justin, Dray, Stéphane, Geras'kin, Stanislav, Glenn, Travis, Higley, Kathy, Ishida, Ken, Kapustka, Lawrence, Kautsky, Ulrik, Kuhne, Wendy, Lynch, Michael, Mappes, Tapio, Mihok, Steve, Møller, Anders P., Mothersill, Carmel, Mousseau, Timothy A., Otaki, Joji M., Pryakhin, Evgeny, Rhodes, Olin E., Salbu, Brit, Strand, Per, and Tsukada, Hirofumi
Abstract:: This paper reports the output of a consensus symposium organized by the International Union of Radioecology in November 2015. The symposium gathered an academically diverse group of 30 scientists to consider the still debated ecological impact of radiation on populations and ecosystems. Stimulated by the Chernobyl and Fukushima disasters' accidental...

Radiometric ⁸¹Kr dating identifies 120,000-year-old ice at Taylor Glacier, Antarctica

Creator:: Buizert, Christo, Baggenstos, Daniel, Jiang, Wei, Purtschert, Roland, Petrenko, Vasilii V., Lu, Zheng-Tian, Mueller, Peter, Lee, James, Severinghaus, Jeffrey P., and Brook, Edward J.
Abstract:: We present the first successful ⁸¹Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ~350 kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The ⁸¹Kr radiometric ages agree with independent...

Hydrothermal Discharge During Submarine Eruptions

Creator:: Baker, Edward T., Chadwick, Wi l l iam W. Jr., Cowen, James P., Dziak, Robert P., Rubin, Kenneth H., and Fornari, Daniel J.
Abstract:: Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to the ocean, but the processes that control these transfers are poorly...

Onset of deglacial warming in West Antarctica driven by local orbital forcing

Creator:: Fudge, T. J., Steig, Eric J., Markle, Bradley R., Schoenemann, Spruce W., Ding, Qinghua, Taylor, Kendrick C., McConnell, Joseph R., Brook, Edward J., Sowers, Todd, White, James W. C., Alley, Richard B., Cheng, Hai, Clow, Gary D., Cole-Dai, Jihong, Conway, Howard, Cuffey, Kurt M., Edwards, Jon S., Edwards, R. Lawrence, Edwards, Ross, Fegyveresi, John M., Ferris, David, Fitzpatrick, Joan J., Johnson, Jay, Hargreaves, Geoffrey, Lee, James E., Maselli, Olivia J., Mason, William, McGwire, Kenneth C., Mitchell, Logan E., Mortensen, Nicolai, Neff, Peter, Orsi, Anais J., Popp, Trevor J., and Schauer, Andrew J.
Abstract:: The cause of warming in the Southern Hemisphere during the most recent deglaciation remains a matter of debate[superscript 1,2]. Hypotheses for a Northern Hemisphere trigger, through oceanic redistributions of heat, are based in part on the abrupt onset of warming seen in East Antarctic ice cores and dated to 18,000...

Using cultural ecosystem services to inform restoration priorities in the Laurentian Great Lakes

Creator:: Allan, J. David, Smith, Sigrid D. P., McIntyre, Peter B., Joseph, Christine A., Dickinson, Caitlin E., Marino, Adrienne L., Biel, Reuben G., Olson, James C., Doran, Patrick J., Rutherford, Edward S., Adkins, Jeffrey E., and Adeyemo, Adesola O.
Abstract:: Ecological restoration programs often attempt to maintain or enhance ecosystem services (ES), but fine-scale maps of multiple ES are rarely available to support prioritization among potential projects. Here we use agency reports, citizen science, and social media as data sources to quantify the spatial distribution of five recreational elements of...

Greenland Temperature Response to Climate Forcing during the Last Deglaciation

Creator:: Buizert, Christo, Gkinis, Vasileios, Severinghaus, Jeffrey P., He, Feng, Lecavalier, Benoit S., Kindler, Philippe, Leuenberger, Markus, Carlson, Anders E., Vinther, Bo, Masson-Delmotte, Valerie, White, James W. C., Liu, Zhengyu, Otto-Bliesner, Bette, and Brook, Edward J.
Abstract:: Greenland ice core water isotopic composition (δ¹⁸O) provides detailed evidence for abrupt climate changes, but is by itself insufficient for quantitative reconstruction of past temperatures and their spatial patterns. We investigate Greenland temperature evolution during the last deglaciation using independent reconstructions from three ice cores and simulations with a coupled...
