    • Abrupt transitions and hysteresis in thermohaline laboratory models 

      Whitehead, John A. (American Meteorological Society, 2009-05)
      As a driving parameter is slowly altered, thermohaline ocean circulation models show either a smooth evolution of a mode of flow or an abrupt transition of temperature and salinity fields from one mode to another. An abrupt ...

      Menezes, Viviane V.; Macdonald, Alison M.; Schatzman, Courtney (American Association for the Advancement of Science, 2017-01-25)
      Southern Ocean abyssal waters, in contact with the atmosphere at their formation sites around Antarctica, not only bring signals of a changing climate with them as they move around the globe but also contribute to that ...
    • 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 ...
    • Accuracy of temperature measurements with the VACM

      For the past five years the Buoy Group at Woods Hole Oceanographic Institution has included temperature as one of the variables recorded in its current meters. These measurements began with the first successful deployments ...
    • Accuracy of the IMET sensor package in the subtropics 

      Colbo, Keir; Weller, Robert A. (American Meteorological Society, 2009-09)
      The accuracies of the meteorological sensors (air temperature, relative humidity, barometric pressure, near-surface temperature, longwave and shortwave radiation, and wind speed and direction) that compose the Improved ...
    • Acoustic doppler current profiling in the Western Pacific during the WOCE P10 cruise, November/December 1993 

      Bahr, Frank B.; Joyce, Terrence M. (Woods Hole Oceanographic Institution, 1997-04)
      The objective of this cruise was to occupy a hydrographic section nominally along 149E from Papua New Guinea to the shelf off the coast of Japan near Yokohama as part of the one-time WOCE Hydrographic Programe survey of ...
    • Acoustic tomography in the Straits of Florida 

      Chester, David B. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1989-09)
      Variability of the Florida Current has been monitored via acoustic tomography. A reciprocal tomography experiment was conducted in the eastern half of the Florida Straits during mid October and November, 1983. A triangular ...
    • Acquisition, description and evaluation of atmospheric model products for the coastal mixing and optics experiments 

      Baumgartner, Mark F.; Anderson, Steven P. (Woods Hole Oceanographic Institution, 1997-03)
      Numerical weather forecasting model products were acquired for use in the Coastal Mixing and Optics (CMO) Experiment to augment in situ observations of meteorological parameters (e.g., wind speed and direction, air ...
    • Adaptive error estimation in linearized ocean general circulation models 

      Chechelnitsky, Michael Y. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-06)
      Data assimilation methods, such as the Kalman filter, are routinely used in oceanography. The statistics of the model and measurement errors need to be specified a priori. In this study we address the problem of estimating ...
