This is the second of three reports that analyze the advective transport in 
Monterey Bay using dynamical systems templates. Here the HF radar data described 
in Part I (Paduan et al) are projected onto numerically derived basis functions 
to produce maps of the surface velocity every two hours. Using dynamical systems 
templates, these maps are used in Part III to delineate transport pathways. The 
projection is used to fill in data voids, ensure compatability with flow 
conditions at open and closed boundaries in the analysis domain, and blend 
disparate data and model output to produce synoptic fields. However, the results 
reported here are based soley on the HF radar observations described in Part I. 
There are two types of basis functins. The vorticity basis is streamfunction 
like and contains all the vertical vorticity. The divergence basis is velocity 
potential like and contains all the horizontal divergence. In three dimensions, 
not discussed here, the complete basis set is incompressible. Data from August 
1994 and June through August 1999 are compared. The percent variance explained 
by each mode shows inconsequential differences between the 1994 and 1999 data 
sets. Spectra of amplitudes from these two periods show strong peaks at one and 
two cycles per day, indicative of tides and wind forcing. There is also energy 
at lower frequencies in the vorticity modes. Thus advective transport models in 
this region must account for both large-scale flow structures and tides.
