  • A CLIMATIC CONTROL ON THE ACCRETION OF METEORIC AND SUPER-CHONDRITIC IRIDIUM-PLATINUM TO THE ANTARCTIC ICE CAP 
    Gabrielli P.; Cescon P.; Barbante C.; Boutron C.F.; Ferrari C.; Petit J.R.; Plane J.M.C.; Hong S.; Cozzi G.; Crutzen P.J.; Lipenkov V.Y. (2006)
    Meteoric smoke particles (MSPs) form through the vaporization of meteoroids and the subsequent re-condensation of metallic species in the mesosphere. Recently, iridium and platinum enrichments have been identified in ...
  • MEASURING GRAVITY ON ICE: AN EXAMPLE FROM WANAPITEI LAKE, ONTARIO, CANADA 
    Ugalde H.A.; L'Heureux E.; Milkereit B.; Lachapelle R. (2006)
    Large lakes have always represented a problem for regional gravity databases; the difficulty of access means gaps or coarse spacing in the sampling. Satellite, airborne, and shipborne gravity techniques are options, but ...
  • SUBSURFACE ICE AS A MICROBIAL HABITAT 
    Mader H.M.; Pettitt M.E.; Parkes R.J.; Wadham J.L.; Wolff E.W. (2006)
    We determine the physicochemical habitat for microorganisms in subsurface terrestrial ice by quantitatively constraining the partitioning of bacteria and fluorescent beads (1-10 μm) between the solid ice crystals and the ...
  • TOMOGRAPHIC IMAGING OF PERMAFROST USING THREE-COMPONENT SEISMIC CONE-PENETRATION TEST 
    LeBlanc A.M.; Fortier R.; Allard M.; Cosma C. (2006)
    We conducted seismic cone-penetration tests (SCPT) and tomographic imaging in a permafrost mound in northern Quebec, Canada, to study the cryostratigraphy and assess the seismic properties of permafrost at temperatures ...
