    • Manatee (Trichechus manatus) vocalization usage in relation to environmental noise levels 

      Miksis-Olds, Jennifer L.; Tyack, Peter L. (Acoustical Society of America, 2009-03)
      Noise can interfere with acoustic communication by masking signals that contain biologically important information. Communication theory recognizes several ways a sender can modify its acoustic signal to compensate for ...
    • A manganese-rich environment supports superoxide dismutase activity in a lyme disease pathogen, Borrelia burgdorferi

      The Lyme disease pathogen Borrelia burgdorferi represents a novel organism in which to study metalloprotein biology in that this spirochete has uniquely evolved with no requirement for iron. Not only is iron low, but we ...
    • Manifestation of the Pacific Decadal Oscillation in the Kuroshio 

      Andres, Magdalena; Park, Jae-Hun; Wimbush, Mark; Zhu, Xiao-Hua; Nakamura, Hirohiko; Kim, Kuh; Chang, Kyung-Il (American Geophysical Union, 2009-08-28)
      Pacific Decadal Oscillation (PDO) index is strongly correlated with vertically integrated transport carried by the Kuroshio through the East China Sea (ECS). Transport was determined from satellite altimetry calibrated ...
    • Mantle 3He distribution and deep circulation in the Indian Ocean 

      Srinivasan, Ashwanth; Top, Zafer; Schlosser, Peter; Hohmann, Roland; Iskandarani, Mohamed; Olson, Donald B.; Lupton, John E.; Jenkins, William J. (American Geophysical Union, 2004-06-10)
      The World Ocean Circulation Experiment Indian Ocean helium isotope data are mapped and features of intermediate and deep circulation are inferred and discussed. The 3He added to the deep Indian Ocean originates from (1) a ...
    • Mantle dynamics beneath the East Pacific Rise at 17°S : insights from the Mantle Electromagnetic and Tomography (MELT) experiment 

      Baba, Kiyoshi; Chave, Alan D.; Evans, Rob L.; Hirth, Greg; Mackie, Randall L. (American Geophysical Union, 2006-02-17)
      The electromagnetic data from the Mantle Electromagnetic and Tomography (MELT) experiment are inverted for a two-dimensional transversely anisotropic conductivity structure that incorporates a correction for three-dimensional ...
    • Mantle flow and melting underneath oblique and ultraslow mid-ocean ridges 

      Montesi, Laurent G. J.; Behn, Mark D. (American Geophysical Union, 2007-12-25)
      Mid-ocean ridge morphology correlates strongly with spreading rate. As the spreading rate decreases, conductive cooling becomes more important in controlling ridge thermal structure and the axial lithosphere thickens. At ...
    • Mantle Pb paradoxes : the sulfide solution 

      Hart, Stanley R.; Gaetani, Glenn A. (2006-04-08)
      There is growing evidence that the budget of Pb in mantle peridotites is largely contained in sulfide, and that Pb partitions strongly into sulfide relative to silicate melt. In addition, there is evidence to suggest ...
