  • Aretxabaleta, Alfredo L.; Smith, Keston W. (2011-01-07)
    An approach to analyze regime change in spatial time series data sets is followed and extended to jointly analyze a dynamical model depicting regime shift and observational data informing the same process. We analyze ...
  • Aretxabaleta, Alfredo L.; Blanton, Brian O.; Seim, Harvey E.; Werner, Francisco E.; Nelson, James R.; Chassignet, Eric P. (American Geophysical Union, 2007-05-11)
    A set of model simulations are used to determine the principal forcing mechanisms that resulted in anomalously cold water in the South Atlantic Bight (SAB) in the summer of 2003. Updated mass field and elevation boundary ...
  • Smith, Keston W.; Aretxabaleta, Alfredo L. (Copernicus Publications on behalf of the European Geosciences Union and the American Geophysical Union, 2007-02-01)
    Expectation maximization (EM) is used to estimate the parameters of a Gaussian Mixture Model for spatial time series data. The method is presented as an alternative and complement to Empirical Orthogonal Function (EOF) ...
  • Aretxabaleta, Alfredo L.; Smith, Keston W.; McGillicuddy, Dennis J.; Ballabrera-Poy, Joaquim (2011-01-24)
    A simple improvement to objective analysis of hydrographic data is proposed to eliminate spatial aliasing e ects in tidally energetic regions. The proposed method consists of the evaluation of anomalies from observations ...
  • Aretxabaleta, Alfredo L.; McGillicuddy, Dennis J.; Smith, Keston W.; Lynch, Daniel R. (American Geophysical Union, 2008-10-29)
    The characteristics of a persistent gyre in the mouth of the Bay of Fundy are studied using model simulations. A set of climatological runs are conducted to evaluate the relative importance of the different forcing mechanisms ...
  • Aretxabaleta, Alfredo L.; McGillicuddy, Dennis J.; Smith, Keston W.; Manning, James P.; Lynch, Daniel R. (American Geophysical Union, 2009-09-03)
    A persistent gyre at the mouth of the Bay of Fundy results from a combination of tidal rectification and buoyancy forcing. Here we assess recent interannual variability in the strength of the gyre using data assimilative ...
