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...

Altimeter estimates of anomalous transports into the northern California Current during 2000–2002

Creator:: Strub, P. Ted and James, Corinne
Abstract:: Surface transports into the California Current are calculated from TOPEX/POSEIDON altimeter surface height slopes during the 9.5 year period from October 1992–May 2002. These quantify the anomalous onshore and southward displacements of the water column during the 2000–2002 period, which had been hypothesized by others based on anomalous water properties...

Routing of western Canadian Plains runoff during the 8.2 ka cold event

Creator:: Carlson, Anders E., Clark, Peter U., 1956-, Haley, Brian A., and Klinkhammer, Gary P.
Abstract:: The collapse of the Laurentide Ice Sheet over Hudson Bay ∼8.47 ka allowed the rapid drainage of glacial Lake Agassiz into the Labrador Sea, an event identified as causing a reduction in Atlantic meridional overturning circulation (AMOC) and the 8.2 ka cold event. Atmosphere‐ocean models simulations based on this forcing,...

Metabolic balance of coastal Antarctic waters revealed by autonomous pCO₂ and ΔO₂/Ar measurements

Creator:: Tortell, Philippe D., Asher, Elizabeth C., Ducklow, Hugh W., Goldman, Johanna A. L., Dacey, John W. H., Grzymski, Joseph J., Young, Jodi N., Kranz, Sven A., Bernard, Kim S., and Morel, François M. M.
Abstract:: We use autonomous gas measurements to examine the metabolic balance (photosynthesis minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...

Observations of internal wave packets propagating along‐shelf in northern Monterey Bay

Creator:: Woodson, C. B., Barth, J. A., Cheriton, O. M., McManus, M. A., Ryan, J. P., Washburn, L., Carden, K. N., Cheng, B. S., Fernandes, J., Garske, L. E., Gouhier, T. C., Haupt, A. J., Honey, K. T., Hubbard, M. F., Iles, A., Kara, L., Lynch, M. C., Mahoney, B., Pfaff, M., Pinsky, M. L., Robart, M. J., Stewart, J. S., Teck, S. J., and True, A.
Abstract:: Internal waves of depression were observed propagating along‐shelf and into northern Monterey Bay, California (CA) on the inner shelf. These waves had amplitudes approximately equal to the thermocline depth (∼4 m), and were unstable to shear and mix the thermocline. Isopycnal gradient spectra showed that the wave packets lead to...

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...

Hypersaline “wet patches” in Taylor Valley, Antarctica

Creator:: Levy, Joseph S., Fountain, Andrew G., Welch, Kathy A., and Lyons, W. Berry
Abstract:: Spatially isolated patches of soil located in Taylor Valley, McMurdo Dry Valleys, Antarctica, are sites of elevated salt content and soil moisture. During Antarctic spring, in the absence of snow melt, visibly wet (reduced albedo) patches of soil are present at the surface. The soil pore fluids are hypersaline and...

The large-scale summer circulation of the California Current

Creator:: Strub, P. Ted and James, Corinne
Abstract:: Satellite data from the Geosat altimeter and the Advanced Very High Resolution Radiometer (AVHRR) are used to show the large-scale structure of the surface circulation of the California Current System in summer. These data show the connection between an equatorward jet and temperature front off Oregon that lies within 100...

Hydro‐isostatic deflection and tectonic tilting in the central Andes: Initial results of a GPS survey of Lake Minchin shorelines

Creator:: Bills, Bruce G., de Silva, Shanaka L., Currey, Donald R., Emenger, Robert S., Lillquist, Karl D., Donnellan, Andrea, and Worden, Bruce
Abstract:: Sufficiently large lake loads provide a means of probing rheological stratification of the crust and upper mantle. Lake Minchin was the largest of the late Pleistocene pluvial lakes in the central Andes. Prominent shorelines, which formed during temporary still‐stands in the climatically driven lake level history, preserve records of lateral...

Turbulence and high-frequency variability in a deep gravity current outflow

Creator:: Nash, Jonathan D., Peters, Hartmut, Kelly, Samuel M., Pelegri, Josep L., Emelianov, Mikhail, and Gasser, Marc
Abstract:: Intensive sampling of the deep Mediterranean outflow 70 km W of the Strait of Gibraltar reveals a strong, tidally modulated gravity current embedded with large-amplitude oscillations and energetic turbulence. The flow appears to be hydraulically controlled at a small topographic constriction, with turbulence and internal waves varying together and increasing...
