    • Deep ocean changes near the Western Boundary of the South Pacific Ocean 

      Sloyan, Bernadette M.; Wijffels, Susan E.; Tilbrook, Bronte; Katsumata, Katsuro; Murata, Akihiko; Macdonald, Alison M. (American Meteorological Society, 2013-10)
      Repeated occupations of two hydrographic sections in the southwest Pacific basin from the 1990s to 2000s track property changes of Antarctic Bottom Water (AABW). The largest property changes—warming, freshening, increase ...
    • Drifter-based estimate of the 5 year dispersal of Fukushima-derived radionuclides 

      Rypina, Irina I.; Jayne, Steven R.; Yoshida, Sachiko; Macdonald, Alison M.; Buesseler, Ken O. (John Wiley & Sons, 2014-11-28)
      Employing some 40 years of North Pacific drifter-track observations from the Global Drifter Program database, statistics defining the horizontal spread of radionuclides from Fukushima nuclear power plant into the Pacific ...
    • Mass, heat, oxygen and nutrient fluxes at 30°S and their implications for the Pacific-Indian through flow and the global heat budget 

      Macdonald, Alison M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-07)
      Six hydrographic basinwide sections, two in each of the three major ocean basins, are employed in a set of inverse calculations to determine the extent of exchange between the Pacific and Indian Oceans through the ...
    • Observed eastward progression of the Fukushima 134Cs signal across the North Pacific 

      Yoshida, Sachiko; Macdonald, Alison M.; Jayne, Steven R.; Rypina, Irina I.; Buesseler, Ken O. (John Wiley & Sons, 2015-09-09)
      Radionuclide samples taken as part of hydrographic surveys at 30°N in the North Pacific reveal that the easternmost edge of Fukushima-derived 134Cs observed at 174.3°W in 2012 had progressed eastward across the basin to ...
    • Oceanic fluxes of mass, heat, and freshwater : a global estimate and perspective 

      Macdonald, Alison M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-08)
      Data from fifteen globally distributed, modern, high resolution, hydrographic oceanic transects are combined in an inverse calculation using large scale box models. The models provide estimates of the global meridional ...
    • The WOCE–era 3–D Pacific Ocean circulation and heat budget 

      Macdonald, Alison M.; Mecking, Sabine; Toole, John M.; Robbins, Paul E.; Johnson, Gregory C.; Wijffels, Susan E.; Talley, Lynne D.; Cook, Margaret F. (2009-08-17)
      To address questions concerning the intensity and spatial structure of the 3–dimensional circulation within the Pacific Ocean and the associated advective and diffusive property flux divergences, data from approximately ...
