Most environmental processes involve variability over both space and
time.  The extension of traditional geostatistical methods, such as
kriging, to the spatio-temporal domain is one possible approach to
characterize this variability.  In this talk, I present this descriptive
approach and an approach that uses a statistical model that is
temporally dynamic and spatially descriptive.  With the inclusion of a
measurement equation, this formulation naturally leads to the
development of a spatio-temporal Kalman filter.  This can be viewed as
empirical Bayesian inference in a hierarchical model.  I then go on to
discuss fully Bayesian inference for spatio-temporal data.
