DC-8-based observations of aircraft CO, CH₄, N₂O, H₂O(G) emission indices during SUCCESS

Creator:: Vay, S. A., Anderson, B. E., Sachse, G. W., Collins, J. E., Podolske, J. R., Twohy, Cynthia, Gandrud, Bruce W., Chan, K. Rolan, Baughcum, S. L., and Wallio, H. A.
Abstract:: We report the first measurements of CO₂, CH₄, N₂O, CO₂, and H₂O(g) in the exhaust trails of T-39, B-757, and DC-8 aircraft at cruise conditions. Emission indices (El) derived from these in-situ measurements are presented. Results are in agreement with ground-based tests indicating aircraft act as a net sink for...

High‐resolution measurements of dissolved organic carbon in the Arctic Ocean by in situ fiber‐optic spectrometry

Creator:: Guay, Christopher K., Klinkhammer, Gary P., Falkner, Kelly, Benner, Ronald, Coble, Paula G., Whiteledge, Terry E., Black, Brenda, Bussell, F. Joseph, and Wagner, Tim A.
Abstract:: Here we report results from an extensive survey of dissolved organic carbon (DOC) in the Arctic Ocean, which was achieved by means of a high-resolution, in situ UV fluorometer deployed on a nuclear submarine. Based on a strong linear correlation observed between fluorescence (320 nm excitation, 420 nm emission) and...

Variations in Gas and Water Pulses at an Arctic Seep: Fluid Sources and Methane Transport

Creator:: Hong, Wei-Li, Torres, Marta E., Portnov, A., Waage, M., Haley, B., and Lepland, A.
Abstract:: Methane fluxes into the oceans are largely dependent on the methane phase as it migrates upward through the sediments. Here we document decoupled methane transport by gaseous and aqueous phases in Storfjordrenna (offshore Svalbard) and propose a three-stage evolution model for active seepage in the region where gas hydrates are...

Paleointensity of the Earth's magnetic field and K-Ar dating of the Louchadiere volcanic flow (Central France) : new evidence for the Laschamp excursion

Creator:: Chauvin, Annick, Duncan, Robert A., Bonhommet, Norbert, and Levi, Saul
Abstract:: We report paleointensity results of the Earth's magnetic field from n Late Pleistocene lava flow (Louchadiere, Central France), which recorded an intermediate geomagnetic field direction (5 sites, mean declination= 114.1°, inclination=58.2°, k=130, α95=6.7°). New K-Ar age determinations confirm that this flow is contemporaneous with the Laschamp and Olby flows, and...

Sources and fate of freshwater exported in the East Greenland Current

Creator:: Dodd, Paul A., Heywood, Karen J., Meredith, Michael P., Naveira-Garabato, Alberto C., Marca, Alina D., and Falkner, Kelly
Abstract:: Monitoring the sources and fate of freshwater in the East Greenland Current (EGC) is important, as this water has the potential to suppress deep convection in the Nordic and Labrador Seas if the outflow of freshwater from the Arctic Ocean increases in response to climate change. Here, hydrographic, oxygen isotope...

Measurements of wave-cloud microphysical properties with two new aicraft probes

Creator:: Gerber, H., Twohy, Cynthia, Gandrud, Bruce W., Heymsfield, Andrew J., McFarquhar, Greg M., DeMott, Paul J., and Rogers, David C.
Abstract:: Measurements of ice water content (IWC) and mean ice-crystal size and concentration made by two in-situ probes, C, VI and PVM, were compared on the DC-8 aircraft during SUCCESS flights in orographic ice clouds. The comparison of 1WC in these wave clouds, that formed at temperatures of about -38 °C...

The response of atmospheric nitrous oxide to climate variations during the last glacial period

Creator:: Schilt, Adrian, Baumgartner, Matthias, Eicher, Olivier, Chappellaz, Jérôme, Schwander, Jakob, Fischer, Hubertus, and Stocker, Thomas F.
Abstract:: Detailed insight into natural variations of the greenhouse gas nitrous oxide (N₂O) in response to changes in the Earth's climate system is provided by new measurements along the ice core of the North Greenland Ice Core Project (NGRIP). The presented record reaches from the early Holocene back into the previous...

Early to Late Holocene Surface Exposure Ages From Two Marine-Terminating Outlet Glaciers in Northwest Greenland

Creator:: Reusche, Melissa M., Marcott, Shaun A., Ceperley, Elizabeth G., Barth, Aaron M., Brook, Edward J., Mix, Alan C., and Caffee, Marc W.
Abstract:: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These...

Last Century Warming Over the Canadian Atlantic Shelves Linked to Weak Atlantic Meridional Overturning Circulation

Creator:: Thibodeau, Benoit, Not, Christelle, Hu, Jiang, Schmittner, Andreas, Noone, David, Tabor, Clay, Zhang, Jiaxu, and Liu, Zhengyu
Abstract:: The Atlantic meridional overturning circulation (AMOC) is a key component of the global climate system. Recent studies suggested a twentieth-century weakening of the AMOC of unprecedented amplitude (similar to 15%) over the last millennium. Here we present a record of O-18 in benthic foraminifera from sediment cores retrieved from the...

Feeding methane vents and gas hydrate deposits at south Hydrate Ridge

Creator:: Tréhu, Anne Martine, Flemings, Peter B., Bangs, Nathan Lawrence Bailey, Chevallier, Johanna, Gracia, Eulalia, Johnson, Joel E., Liu, C. S., Liu, Xiaoli, Riedel, Michael, and Torres, Marta E.
Abstract:: Log and core data document gas saturations as high as 90% in a coarse-grained turbidite sequence beneath the gas hydrate stability zone (GHSZ) at south Hydrate Ridge, in the Cascadia accretionary complex. The geometry of this gas-saturated bed is defined by a strong, negative-polarity reflection in 3D seismic data. Because...
