  • Escartin Guiral, Javier E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-08)
    Two-thirds of the Earth's surface is oceanic crust formed by magmatic and tectonic processes along mid-ocean ridges. Slow-spreading ridges, such as the Mid-Atlantic Ridge, are discontinuous and composed of ridge segments. ...
  • Das, Sarah B.; Alley, Richard B. (American Geophysical Union, 2008-01-29)
    A new melt layer history from Siple Dome, West Antarctica, indicates notable late-Holocene summertime warming. Visual stratigraphic analyses of the 1004-m ice core identified 62 years with melt layers. Melting events began ...
  • Matsuno, Tetsuo; Chave, Alan D.; Jones, Alan G.; Muller, Mark R.; Evans, Rob L. (Oxford University Press on behalf of The Royal Astronomical Society, 2014-01-02)
    A robust magnetotelluric (MT) inversion algorithm has been developed on the basis of quantile-quantile (q-q) plotting with confidence band and statistical modelling of inversion residuals for the MT response function ...
  • Keigwin, Lloyd D.; Cook, Mea S. (American Geophysical Union, 2007-07-11)
    A simple ocean/atmosphere feedback may reduce the amplitude of climate variability in around the North Atlantic during interglacial compared to glacial states. When climate is warm in the North Atlantic region, the ...
  • Sigman, Daniel M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-09)
    This dissertation contributes to the search for a cause of glacial/interglacial variations in atmospheric carbon dioxide. The hypotheses addressed involve changes in low and high-latitude biological export production. A ...
  • Liu, Yajing; Rubin, Allan M. (American Geophysical Union, 2010-10-16)
    In the vicinity of episodic aseismic transients in several subduction zones, the presence of interstitial fluids and near-lithostatic pore pressure has been proposed to interpret seismic observations of high P to S wave ...
  • Tucholke, Brian E.; Behn, Mark D.; Buck, W. Roger; Lin, Jian (Geological Society of America, 2008-06)
    Normal faults are ubiquitous on mid-ocean ridges and are expected to develop increasing offset with reduced spreading rate as the proportion of tectonic extension increases. Numerous long-lived detachment faults that form ...
  • Trusel, Luke D.; Frey, Karen E.; Das, Sarah B.; Munneke, Peter Kuipers; van den Broeke, Michiel R. (John Wiley & Sons, 2013-12-04)
    This study generates novel satellite-derived estimates of Antarctic-wide annual (1999–2009) surface meltwater production using an empirical relationship between radar backscatter from the QuikSCAT (QSCAT) satellite and ...
  • Wolfteich, Carl M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-02)
    Planktonic foraminiferal flux was collected at four sediment trap locations spanning a 34° latitude range in the North Atlantic during 1988-1990. Satellite-derived sea surface temperature (SST) and CTD data were integrated ...
  • Hart, Stanley R.; Kurz, Mark D.; Wang, Z. (2008-02-23)
    A model of coupled He production/diffusion is used to constrain the question of whether Earth’s peridotitic mantle contains ubiquitous mesoscale veins or slabs of other lithologies. The high diffusion rates of helium ...
  • Boettcher, Margaret S.; McGuire, Jeffrey J. (American Geophysical Union, 2009-11-04)
    Mid-ocean ridge transform faults (RTFs) have thermal structures that vary systematically with tectonic parameters, resulting in predictable seismic characteristics and clear seismic cycles. We develop a scaling relation ...
  • Klein, Emily M.; White, Scott M.; Nunnery, James Andrew; Mason-Stack, Jessica L.; Wanless, V. Dorsey; Perfit, Michael R.; Waters, Christopher L.; Sims, Kenneth W. W.; Fornari, Daniel J.; Zaino, Anne J.; Ridley, W. Ian (John Wiley & Sons, 2013-12-20)
    A fundamental goal in the study of mid-ocean ridges is to understand the relationship between the distribution of melt at depth and seafloor features. Building on geophysical information on subsurface melt at the 9°N ...
  • Konter, Jasper G.; Staudigel, Hubert; Hart, Stanley R.; Shearer, P. M. (American Geophysical Union, 2004-06-26)
    We deployed five ocean bottom hydrophones (OBHs) for a 1-year seismic monitoring study of Vailulu'u Seamount, the youngest and easternmost volcano in the Samoan Archipelago. Four instruments were placed on the summit crater ...
  • Padman, Laurie; Costa, Daniel P.; Bolmer, S. Thompson; Goebel, Michael E.; Huckstadt, Luis A.; Jenkins, Adrian; McDonald, Birgitte I.; Shoosmith, Deborah R. (American Geophysical Union, 2010-11-03)
    We demonstrate the first use of marine mammal dive-depth data to improve maps of bathymetry in poorly sampled regions of the continental shelf. A group of 57 instrumented elephant seals made on the order of 2 × 105 dives ...
  • Aubry, Marie-Pierre (2008-05-27)
    Smaller size is generally seen as a negative response of organisms to stressful environmental conditions, associated with low diversity and species dominance. The mean size of the coccolithophorids decreased through the ...
  • Collins, John A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-10-06)
    The results of numerous seismic refraction and reflection experiments have shown that the seismic structure of the oceanic crust can be usefully parameterized by a small number of locally horizontal layers within which ...
  • Bhatia, Maya P.; Das, Sarah B.; Kujawinski, Elizabeth B.; Henderson, Paul B.; Burke, Andrea; Charette, Matthew A. (International Glaciological Society, 2011-10-01)
    The Greenland ice sheet (GrIS) subglacial hydrological system may undergo a seasonal evolution, with significant geophysical and biogeochemical implications. We present results from a new isotope-mixing model to quantify ...
  • Keigwin, Lloyd D.; Bice, Marley; Copley, Nancy J. (American Geophysical Union, 2005-07-18)
    Monthly samples of stratified plankton tows taken from the slope waters off Cape Cod nearly 25 years ago are used to describe the seasonal succession of planktonic foraminifera and their oxygen isotope ratios. The 15°C ...
  • Dahl, Kristina A.; Oppo, Delia W. (American Geophysical Union, 2006-03-28)
    Sea surface temperature (SST) and seawater δ18O (δ18Ow) were reconstructed in a suite of sediment cores from throughout the Arabian Sea for four distinct time intervals (0 ka, 8 ka, 15 ka, and 20 ka) with the aim of ...
  • Oppo, Delia W.; Schmidt, Gavin A.; LeGrande, Allegra N. (American Geophysical Union, 2007-07-03)
    Paleoceanographic data from the low latitude Pacific Ocean provides evidence of changes in the freshwater budget and redistribution of freshwater within the basin during the Holocene. Reconstructed Holocene seawater δ 18O ...
