  • Woodgate, Rebecca A,; Aagaard, Knut; Swift, James H.; Smethie, William M.; Falkner, Kelly (American Geophysical Union, 2007-02-03)
    Hydrographic and tracer data from 2002 illustrate Atlantic water pathways and variability in the Mendeleev Ridge and Chukchi Borderland (CBLMR) region of the Arctic Ocean. Thermohaline double diffusive intrusions (zigz ...
  • Azetsu-Scott, Kumiko; Clarke, Allyn; Falkner, Kelly; Hamilton, James; Jones, E. Peter; Lee, Craig; Petrie, Biran; Prinsenberg, Simon; Starr, Michel; Yeats, Philip (American Geophysical Union, 2010-11-23)
    Ocean acidification is predicted to occur first in polar oceans. We investigated the saturation state of waters with respect to calcite (Wcal) and aragonite (Warg) in six sections along an Arctic outflow pathway throug ...
  • Macdonald, R. W.; Carmack, E. C.; McLaughlin, F. A.; Falkner, Kelly; Swift, J. H. (American Geophysical Union, 1999-08-01)
    During SHEBA, thin ice and freshening of the Arctic Ocean surface in the Beafort Sea led to speculation that perennial sea ice was disappearing [McPhee et al., 1998]. Since 1987, we have collected salinity, δ¹⁸O and Ba p ...
  • Guay, Christopher K.; Klinkhammer, Gary P.; Falkner, Kelly; Benner, Ronald; Coble, Paula G.; Whiteledge, Terry E.; Black, Brenda; Bussell, F. Joseph; Wagner, Tim A. (American Geophysical Union, 1999-04-15)
    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 ...
  • Falkner, Kelly; Measures, Chris I.; Herbelin, Sarah E.; Edmond, John M.; Weiss, Ray F. (American Society of Limnology and Oceanography, 1991-05)
    A comprehensive, joint Soviet-American study of the chemistry of Lake Baikal, the world’s deepest (1,632 m) lake, was carried out in July 1988. In this paper, we report the major, minor, and preliminary trace element con ...
  • Falkner, Kelly; Church, M.; Measures, Chris I.; LeBaron, G.; Thouron, D.; Jeandel, C.; Stordal, M. C.; Gill, G. A.; Mortlock, R.; Froelich, P.; Chan, L.-H. (American Society of Limnology and Oceanography, 1997)
    A Russian–American fieldwork effort on Lake Baikal, its tributaries, and surrounding hot springs was undertaken in June–July 1991. Here we report on aspects of major ion (Ca2+, Mg2+, Na+, K+, Alk, Cl–, SO42–) and several ...
  • Woodgate, Rebecca A.; Aagaard, Knut; Swift, James H.; Falkner, Kelly; Smethie, William M. (American Geophysical Union, 2005-09-29)
    Pacific winter waters, a major source of nutrients and buoyancy to the Arctic Ocean, are thought to ventilate the Arctic's lower halocline either by injection (isopycnal or penetrative) of cold saline shelf waters, or by ...
  • Taylor, John Ryan; Falkner, Kelly; Schauer, Ursula; Meredith, Mike (American Geophysical Union, 2003-12-05)
    Dissolved barium (Ba) was measured along transects across Fram and Denmark Straits as part of the 1998 ARK-XIV/2 Polarstern expedition. Results are combined with other available tracer observations to analyze water mas ...
  • Morison, J.; Steele, M.; Kikuchi, T.; Falkner, Kelly; Smethie, W. (American Geophysical Union, 2006-09-08)
    Upper ocean hydrography in the central Arctic Ocean has relaxed since 2000 to near-climatological conditions that pertained before the dramatic changes of the 1990s. The behavior of the anomalies of temperature and sa ...
  • Dodd, Paul A.; Heywood, Karen J.; Meredith, Michael P.; Naveira-Garabato, Alberto C.; Marca, Alina D.; Falkner, Kelly (American Geophysical Union, 2009-10-13)
    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 ...
  • Sherrell, R. M.; Boyle, E. A.; Harris, N. R.; Falkner, Kelly (American Geophysical Union and the Geochemical Society, 2000-05-30)
    We present a decade-long (1981–1990) high-resolution (subseasonal) record of Pb and Cd concentrations and Pb isotopic composition in a series of 119 snow samples from a 6-m snow pit at Summit, Greenland. Both metals sh ...
  • Alleau, Y.; Colbert, D.; Covert, P.; Haley, Brian A.; Qiu, X.; Collier, Robert W.; Falkner, Kelly; Hales, Burke; Prahl, Fredrick; Gordon, L. (American Geophysical Union, 2001-07-15)
    It has been recognized since the 1950's that radioisotopic disequilibrium between naturally occurring parent-daughter isotope pairs in seawater can provide information on the rate of processes segregating them. In the ...
  • Abrahamsen, E. Povl; Meredith, Michael P.; Falkner, Kelly; Torres-Valdes, Sinhue; Leng, Melanie J.; Alkire, Matthew B.; Bacon, Sheldon; Laxon, Seymour W.; Polyakov, Igor; Ivanov, Vladimir (American Geophysical Union, 2009-04-02)
    We investigate the freshwater composition of the shelf and slope of the Arctic Ocean north of the New Siberian Islands using geochemical tracer data (δ¹⁸O, Ba, and PO₄*) collected following the extreme summer of 2007. ...
  • Jones, E. P.; Swift, J. H.; Anderson, L. G.; Lipizer, M.; Civitarese, G.; Falkner, Kelly; Kattner, G.; McLaughlin, F. A. (American Geophysical Union, 2003-04-12)
    In the Arctic Ocean, Pacific source water can be distinguished from Atlantic source water by nitrate-phosphate concentration relationships, with Pacific water having higher phosphate concentrations relative to those of ...
  • Guay, Christopher K. H.; Falkner, Kelly; Muench, Robin D.; Mensch, Manfred; Frank, Markus; Bayer, Reinhold (American Geophysical Union, 2001-06-15)
    Distributions of temperature, salinity, and barium in near-surface waters (depth ≤ 50 m) of the Laptev Sea and adjacent areas of the Arctic Ocean are presented for the summers of 1993, 1995, and 1996. The tracer data ind ...
