    Folding of stratigraphic layers in ice domes 

    Jacobson, Herbert Paul (2001)
    This dissertation presents a two part model of the formation of recumbent folds in stratigraphic layers of ice sheets such as those in Greenland and Antarctica. The initial disturbances in the stratigraphy have their roots in transient dynamic processes and local rheological inhomogeneities, but the kinematics of even a simple ...

    Fluid and particle simulations of the interaction of the solar wind with magnetic anomalies on the surface of the Moon and Mars 

    Harnett, Erika Megan (2003)
    Simulations of the solar wind interacting with the Moon and Mars indicate that the presence of magnetic anomalies on the surface can lead to the formation of mini-magnetospheres around the anomalies. These mini-magnetospheres are not just small scale versions of planetary magnetospheres, but rather their small size leads to ...

    The indepth magnetotelluric experiment on the Tibetan Plateau and its implications 

    Li, Shenghui (2001)
    This dissertation focus on the application of the magnetotelluric method to tectonic studies on the Tibetan Plateau. The framework of this thesis composes three parts. The first part concentrates on magnetotelluric data inversion in the presence of strong topographic or bathymetric distortions. A new approach is described to ...

    Behavior of the atomic oxygen 5577 Ångström emission intensity at mid-latitudes: a climatological view 

    Deutsch, Kerry Ann (2000)
    A global mid-latitude study of the atomic oxygen green line emission intensity at 5577 A has been undertaken with the goal of developing a climatological understanding of the emission behavior and its usefulness as a tracer for the atmosphere near 97 km. Long-term observations have been analysed at nine stations covering ...

    Effects of firn ventilation on geochemistry of polar snow 

    Neumann, Thomas A., 1973- (2003)
    The effects of air motion in firn on geochemical species is examined. Stable isotope data from Taylor Mouth, Antarctica are compared with data from nearby Taylor Dome and are found to be significantly different. Three possible reasons for the difference between these two records are presented: (1) the standard stable isotope ...

    High pressure and low temperature equations of state for aqueous magnesium sulfate: applications to the search for life in extraterrestrial oceans, with particular reference to Europa 

    Vance, Steven, 1978- (2007)
    A prevalence of cold, high pressure (P > 100 MPa) environments in the Solar System, and beyond, is discussed in the context of contemporary efforts to understand the origin and abundance of life in the Universe. Constraints on the depths of fluid circulation in extraterrestrial seafloors are explored through a model for the ...

    Kinetic processes in the plasma sheet observed during auroral activity 

    Fillingim, Matthew Owen (2002)
    In this dissertation we analyze plasma sheet magnetic field and plasma data observed during varying levels of auroral activity from very small, isolated events known as pseudobreakups to large, global events known as substorms. The plasma and magnetic field data are taken from instruments onboard the WIND spacecraft while it ...

    Juan de Fuca subducting plate geometry and intraslab seismicity 

    Medema, Guy Frederick (2006)
    The geometry of the subducting Juan de Fuca plate beneath the Olympic Peninsula of Western Washington is modeled using wide-angle P mP reflections off the slab Moho. Active-source reflection data collected from the 1998 WET SHIPS project were augmented with earthquake-source reflections to increase the spatial distribution ...

    Interpretation of infrasound generated by erupting volcanoes and seismo-acoustic energy partitioning during strombolian explosions 

    Johnson, Jeffrey B., 1972- (2000)
    Infrasonic signals provide a valuable tool for the study of volcanic eruptions because volcanoes generate the majority of their acoustic energy in the infrasonic bandwidth and infrasound is only slightly affected by propagation filters, transmission losses, dispersion, and instrument site responses. Though changing atmospheric ...
