Data File Format
----------------

Each matlab-formated file (sbi04_bsX_2004f.mat)) contains the moored ADCP 
data for station X for deployment ending in year 2004. The ADCP 
data has been edited for outliers using error velocity and percent 
good threshold criteria. Bad data points have been replaced 
with NaN values. ADCP compass has been corrected for magnetic variation. 
Each station contains the structures variables which are described below:
