  • Radiating instability of a meridional boundary current 

    Hristova, Hristina G.; Pedlosky, Joseph; Spall, Michael A. (American Meteorological Society, 2008-10)
    A linear stability analysis of a meridional boundary current on the beta plane is presented. The boundary current is idealized as a constant-speed meridional jet adjacent to a semi-infinite motionless far field. The far-field ...
  • Radiating instability of nonzonal ocean currents 

    Kamenkovich, Igor V. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-09)
    This thesis addresses the question of how a highly energetic eddy field could be generated in the interior of the ocean away from the swift boundary currents. The energy radiation due to the temporal growth of non-trapped ...
  • Radiation and dissipation of internal waves generated by geostrophic motions impinging on small-scale topography 

    Nikurashin, Maxim (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-02)
    Observations and inverse models suggest that small-scale turbulent mixing is enhanced in the Southern Ocean in regions above rough topography. The enhancement extends 1 km above the topography suggesting that mixing is ...
  • Radium-based estimates of cesium isotope transport and total direct ocean discharges from the Fukushima Nuclear Power Plant accident 

    Charette, Matthew A.; Breier, Crystaline F.; Henderson, Paul B.; Pike, Steven M.; Rypina, Irina I.; Jayne, Steven R.; Buesseler, Ken O. (Copernicus Publications on behalf of the European Geosciences Union, 2013-03-28)
    Radium has four naturally occurring isotopes that have proven useful in constraining water mass source, age, and mixing rates in the coastal and open ocean. In this study, we used radium isotopes to determine the fate and ...
  • RAFOS float processing at the Woods Hole Oceanographic Institution 

    Wooding, Christine M.; Furey, Heather H.; Pacheco, Marguerite A. (Woods Hole Oceanographic Institution, 2005-01)
    This report and its accompanying webpage (http://www.whoi.edu/science/PO/rafos/index.htm) describe the processing steps for RAFOS floats, from subscribing to Service Argos to plotting the final data for a data report. ...
  • RAFOS float trajectories in Meddies during the Semaphore Experiment, 1993-1995 

    Richardson, Philip L.; Wooding, Christine M. (Woods Hole Oceanographic Institution, 1999-04)
    As part of the Semaphore Experiment four Meddies (Mediterranean Water Eddies) were discovered in the Canary Basin and tracked with freely drifting RAFOS floats. An additional Meddy was discovered off Lisbon by Pingree ...
  • RAMA : the Research Moored Array for African–Asian–Australian Monsoon Analysis and Prediction 

    McPhaden, Michael J.; Meyers, G.; Ando, K.; Masumoto, Y.; Murty, V. S. N.; Ravichandran, M.; Syamsudin, F.; Vialard, J.; Yu, Lisan; Yu, W. (American Meteorological Society, 2009-04)
    The Indian Ocean is unique among the three tropical ocean basins in that it is blocked at 25°N by the Asian landmass. Seasonal heating and cooling of the land sets the stage for dramatic monsoon wind reversals, strong ...
  • Random-forcing model of the mesoscale oceanic eddies 

    Berloff, Pavel S. (Cambridge University Press, 2005-04-01)
    The role of mesoscale oceanic eddies in driving large-scale currents is studied in an eddy-resolving midlatitude double-gyre ocean model. The reference solution is decomposed into large-scale and eddy components in a way ...
