  • Absarokites from the Western Mexican Volcanic Belt : constraints on mantle wedge conditions 

    Hesse, Marc (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-08)
    We have investigated the near liquidus phase relations of a primitive absarokite from the Mascota region in Western Mexico. Sample M.102 was chosen because it has high MgO contents, a high Mg# and F090 olivine phenocrysts, ...
  • Absolute probability estimates of lethal vessel strikes to North Atlantic right whales in Roseway Basin, Scotian Shelf 

    van der Hoop, Julie M.; Vanderlaan, Angelia S. M.; Taggart, Christopher T. (Ecological Society of America, 2012-10)
    Vessel strikes are the primary source of known mortality for the endangered North Atlantic right whale (Eubalaena glacialis). Multi-institutional efforts to reduce mortality associated with vessel strikes include vessel-routing ...

    Hall, Melinda M.; Torres, Daniel J.; Yashayaev, Igor (Elsevier B.V., 2012-11-19)
    Nearly every spring since 1990, hydrographic data have been collected along a section in the Labrador Sea known as AR7W. Since 1995, lowered acoustic doppler current profiler (LADCP) data have also been collected. In this ...

  • Abundance and diversity of archaeal ammonia oxidizers in a coastal groundwater system 

    Rogers, Daniel R.; Casciotti, Karen L. (2010-10-12)
    Nitrification, the microbially-catalyzed oxidation of ammonia to nitrate, is a key process in the nitrogen cycle. Archaea have been implicated in the first part of the nitrification pathway (oxidation of ammonia to ...
  • Abundance and diversity of ascidians in the southern Gulf of Chiriquí, Pacific Panama 

    Bullard, Stephan G.; Carman, Mary R.; Rocha, Rosana M.; Dijkstra, Jennifer A.; Goodwin, Anne M. (Regional Euro-Asian Biological Invasions Centre (REABIC), 2011-07-04)
    Little is known about the ascidian fauna of Pacific Panama. Ascidian surveys were conducted in the southern Gulf of Chiriquí on the Pacific coast of Panama in January 2008 and 2009. Surveys along linear transects at 2-3 m ...
  • Abyssal mixing from bottom boundary effects in Mid-Atlantic Ridge flank canyons 

    Dell, Rebecca Walsh (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2010-06)
    This paper begins to explore a previously neglected mechanism for abyssal ocean mixing using bottom boundary layer dynamics. Abyssal mixing and the associated upward buoyancy fluxes are necessary to balance the sinking ...
  • Accelerated settling of particulate matter by ’marine snow’ aggregates 

    Asper, Vernon L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1985-12)
    Samples from time-series sediment traps deployed in three distinct oceanographic settings (North Pacific, Panama Basin, and Black Sea) provide strong evidence for rapid settling of marine particles by aggregates. Particle ...
  • Acceleration of a stratified current over a sloping bottom, driven by an alongshelf pressure gradient 

    Chapman, David C.; Lentz, Steven J. (American Meteorological Society, 2005-08)
    An idealized theoretical model is developed for the acceleration of a two-dimensional, stratified current over a uniformly sloping bottom, driven by an imposed alongshelf pressure gradient and taking into account the effects ...
