  • Minimum distribution of subsea ice-bearing permafrost on the U.S. Beaufort Sea continental shelf 

    Brothers, Laura L.; Hart, Patrick E.; Ruppel, Carolyn D. (American Geophysical Union, 2012-08-07)
    Starting in Late Pleistocene time (~19 ka), sea level rise inundated coastal zones worldwide. On some parts of the present-day circum-Arctic continental shelf, this led to flooding and thawing of formerly subaerial permafrost ...
  • 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 ...
