  • Vertical motions of the Puerto Rico Trench and Puerto Rico and their cause 

    ten Brink, Uri S. (American Geophysical Union, 2005-06-22)
    The Puerto Rico trench exhibits great water depth, an extremely low gravity anomaly, and a tilted carbonate platform between (reconstructed) elevations of +1300 m and −4000 m. I argue that these features are manifestations ...
  • Volume change associated with formation and dissociation of hydrate in sediment 

    Lee, J. Y.; Santamarina, J. Carlos; Ruppel, Carolyn D. (American Geophysical Union, 2010-03-11)
    Gas hydrate formation and dissociation in sediments are accompanied by changes in the bulk volume of the sediment and can lead to changes in sediment properties, loss of integrity for boreholes, and possibly regional ...
  • Widespread gas hydrate instability on the upper U.S. Beaufort margin 

    Phrampus, Benjamin J.; Hornbach, Matthew J.; Ruppel, Carolyn D.; Hart, Patrick E. (John Wiley & Sons, 2014-12-09)
    The most climate-sensitive methane hydrate deposits occur on upper continental slopes at depths close to the minimum pressure and maximum temperature for gas hydrate stability. At these water depths, small perturbations ...
