  • Ponton, Camilo; Giosan, Liviu; Eglinton, Timothy I.; Fuller, Dorian Q.; Johnson, Joel E.; Kumar, Pushpendra; Collett, Timothy S. (American Geophysical Union, 2012-02-14)
    Spanning a latitudinal range typical for deserts, the Indian peninsula is fertile instead and sustains over a billion people through monsoonal rains. Despite the strong link between climate and society, our knowledge of ...
  • Hu, Dengke; Clift, Peter D.; Boning, Philipp; Hannigan, Robyn E.; Hillier, Stephen; Blusztajn, Jerzy S.; Wan, Shiming; Fuller, Dorian Q. (John Wiley & Sons, 2013-07-26)
    Sediments in the Pearl River delta have the potential to record the weathering response of this river basin to climate change since 9.5 ka, most notably weakening of the Asian monsoon since the Early Holocene (∼8 ka). Cores ...
  • Dziak, Robert P.; Bohnenstiehl, DelWayne R.; Smith, Deborah K. (The Oceanography Society, 2012-03)
    Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means ...
  • Aubrey, David G.; Oguz, T.; Demirev, E.; Ivanov, V.; McSherry, T. R.; Diaconu, V.; Nikolaenko, E. (Woods Hole Oceanographic Institution, 1992-02)
    An Intercalibration Workshop was held at the Woods Hole Oceanographic Institution (W.H.O.I.) from 1-10 December, 1991, for the CTD data acquired during HYDROBLACK '91. This intercalibration exercise was a prelude to an ...
  • Salles, Paulo (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-02)
    The importance of the persistence of multiple inlets in coastal systems is fundamental for issues such as water quality, navigability, and beach/barrier stability. In long embayments, having extended residence times, the ...
  • Geist, Eric L.; Lynett, Patrick J.; Chaytor, Jason D. (Elsevier B.V., 2008-10-18)
    Tsunami generation from the Currituck landslide offshore North Carolina and propagation of waves toward the U.S. coastline are modeled based on recent geotechnical analysis of slide movement. A long and intermediate wave ...
  • Friedrichs, Carl T. (Woods Hole Oceanographic Institution, 1993-02)
    In this thesis, mechanisms which control morphodynamics of shallow tidal embayments are investigated analytically. In the process of exploring these mechanisms (specifically asymmetries in bottom stress, τ), basis momentum ...
  • Benway, Heather M.; McManus, Jerry F.; Oppo, Delia W.; Cullen, James L. (2010-08)
    Millennial-scale climate fluctuations of the last deglaciation have been tied to abrupt changes in the Atlantic Meridional Overturning Circulation (MOC). A key to understanding mechanisms of MOC collapse and recovery is ...
  • Bhatia, Maya P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-02)
    Global warming has led to a significant increase in Greenland ice sheet (GrIS) melt and runoff since 1990, resulting in escalated export of fresh water and associated sediment to the surrounding North Atlantic and Arctic ...
  • Vidal, L.; Menot, G.; Joly, C.; Bruneton, H.; Rostek, F.; Cagatay, M. Namik; Major, Candace O.; Bard, Edouard (American Geophysical Union, 2010-02-06)
    Sediments deposited under lacustrine and marine conditions in the Sea of Marmara hold a Late Quaternary record for water exchange between the Black Sea and the Mediterranean Sea. Here we report a multiproxy data set based ...
  • Connelly, Douglas P.; German, Christopher R.; Asada, Miho; Okino, K.; Egorov, A.; Naganuma, T.; Pimenov, N.; Cherkashev, G.; Tamaki, K. (American Geophysical Union, 2007-08-28)
    We report first evidence for hydrothermal activity from the southern Knipovich Ridge, an ultra-slow spreading ridge segment in the Norwegian-Greenland Sea. Evidence comes from optical backscatter anomalies collected during ...
  • Humphris, Susan E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1976-10)
    Considerable geological and geophysical evidence now exists to support the hypothesis that seawater circulates through freshly intruded basalt at the mid-ocean ridges. As a consequence of this process, reactions between ...
  • Johnson, H. Paul; Tivey, Maurice A.; Bjorklund, Tor A.; Salmi, Marie S. (American Geophysical Union, 2010-05-06)
    Areas of the seafloor at mid-ocean ridges where hydrothermal vents discharge are easily recognized by the dramatic biological, physical, and chemical processes that characterize such sites. Locations where seawater flows ...
  • Baker, Edward T.; Chadwick, William W.; Cowen, James P.; Dziak, Robert P.; Rubin, Kenneth H.; Fornari, Daniel J. (The Oceanography Society, 2012-03)
    Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and ...
  • German, Christopher R.; Resing, Joseph A.; Prien, R. D.; Walker, Sharon L.; Edmonds, Henrietta N.; Langmuir, Charles H. (American Geophysical Union, 2006-11-29)
    We report evidence for active hydrothermal venting along two back-arc spreading centers of the NE Lau Basin: the Fonualei Rift and Spreading Center (FRSC) and the Northeast Lau Spreading Center (NELSC). The ridge segments ...
  • Fontaine, Fabrice J.; Olive, Jean-Arthur; Cannat, Mathilde; Escartin, Javier; Perol, Thibaut (American Geophysical Union, 2011-07-28)
    The heat output and thermal regime of fast and intermediate spreading centers are strongly controlled by boundary layer processes between the hydrothermal system and the underlying crustal magma chamber (AMC), which remain ...
  • Chavagnac, Valerie; Palmer, Martin R.; Milton, J. Andrew; Green, Darryl R. H.; German, Christopher R. (American Geophysical Union, 2006-09-09)
    Geochemical compositions and Sr and Nd isotopes were measured in two cores collected ~2 and 5 km from the Rainbow hydrothermal vent site on the Mid-Atlantic Ridge. Overall, the cores record enrichments in Fe and other ...
  • Connelly, Douglas P.; Copley, Jonathan T.; Murton, Bramley J.; Stansfield, Kate; Tyler, Paul A.; German, Christopher R.; Van Dover, Cindy L.; Amon, Diva; Furlong, Maaten; Grindlay, Nancy; Hayman, Nicholas W.; Huhnerbach, Veit; Judge, Maria; Le Bas, Tim; McPhail, Stephen; Meier, Alexandra; Nakamura, Ko-ichi; Nye, Verity; Pebody, Miles; Pedersen, Rolf B.; Plouviez, Sophie; Sands, Carla M.; Searle, Roger C.; Stevenson, Peter; Taws, Sarah; Wilcox, Sally (Nature Publishing Group, 2012-01-10)
    The Mid-Cayman spreading centre is an ultraslow-spreading ridge in the Caribbean Sea. Its extreme depth and geographic isolation from other mid-ocean ridges offer insights into the effects of pressure on hydrothermal ...
  • Staudigel, Hubert; Hart, Stanley R.; Koppers, Anthony A. P.; Constable, C.; Workman, Rhea K.; Kurz, Mark D.; Baker, Edward T. (American Geophysical Union, 2004-02-10)
    The summit crater of Vailulu'u Seamount, the youngest volcano in the Samoan chain, hosts an active hydrothermal system with profound impact on the ocean water column inside and around its crater (2 km wide and 407 m deep ...
  • Baker, Edward T.; Edmonds, Henrietta N.; Michael, Peter J.; Bach, Wolfgang; Dick, Henry J. B.; Snow, Jonathan E.; Walker, Sharon L.; Banerjee, Neil R.; Langmuir, Charles H. (American Geophysical Union, 2004-08-18)
    Detailed hydrothermal surveys over ridges with spreading rates of 50–150 mm/yr have found a linear relation between spreading rate and the spatial frequency of hydrothermal venting, but the validity of this relation at ...
