    • A catastrophic meltwater flood event and the formation of the Hudson Shelf Valley 

      Thieler, E. Robert; Butman, Bradford; Schwab, William C.; Allison, Mead A.; Driscoll, Neal W.; Donnelly, Jeffrey P.; Uchupi, Elazar (Elsevier B.V., 2007-01-04)
      The Hudson Shelf Valley (HSV) is the largest physiographic feature on the U.S. mid-Atlantic continental shelf. The 150-km long valley is the submerged extension of the ancestral Hudson River Valley that connects to the ...
    • Characteristics and dynamics of two major Greenland glacial fjords 

      Sutherland, David A.; Straneo, Fiamma; Pickart, Robert S. (John Wiley & Sons, 2014-06-16)
      The circulation regimes of two major outlet glacial fjords in southeastern Greenland, Sermilik Fjord (SF) and Kangerdlugssuaq Fjord (KF), are investigated using data collected in summer 2009. The two fjords show similar ...
    • The five stable noble gases are sensitive unambiguous tracers of glacial meltwater 

      Loose, Brice; Jenkins, William J. (John Wiley & Sons, 2014-04-16)
      The five inert noble gases—He, Ne, Ar, Kr, and Xe—exhibit a unique dissolved gas saturation pattern resulting from the formation and addition of glacial meltwater to seawater. He and Ne become oversaturated, and Ar, Kr, ...
    • Spreading of Greenland meltwaters in the ocean revealed by noble gases 

      Beaird, Nicholas; Straneo, Fiamma; Jenkins, William J. (John Wiley & Sons, 2015-09-30)
      We present the first noble gas observations in a proglacial fjord in Greenland, providing an unprecedented view of surface and submarine melt pathways into the ocean. Using Optimum Multiparameter Analysis, noble gas ...
    • Utility of Rn-222 as a passive tracer of subglacial distributed system drainage 

      Linhoff, Benjamin S.; Charette, Matthew A.; Nienow, Peter W.; Wadham, Jemma L.; Tedstone, Andrew; Cowton, Thomas (Elsevier, 2017-01-23)
      Water flow beneath the Greenland Ice Sheet (GrIS) has been shown to include slow-inefficient (distributed) and fast-efficient (channelized) drainage systems, in response to meltwater delivery to the bed via both moulins ...
