Subject: certain PSS files replaced

Hi all,

Hank Vanderploeg and Jim Liebig have completed work to develop regression equations to 
predict Chl-a from PSS fluorescence output and TSM from PSS light attentuation.  Regressions 
were developed for the  "pre-plume" (January-February), "plume" (March) and "post-plume" 
(early and late April) cruises 1998-2000.

For a complete description of the methods used in developing these regression equations, 
see http://www.glerl.noaa.gov/eegle/data/1998/pss_vanderploeg/pss1.met.  See in particular 
the two MS Word files that are linked to in this meta data file.

I have replaced all PSS files in the EEGLE Database that correspond to the following cruises:
surv-1998-028
surv-1998-068
surv-1999-046
surv-1999-067
surv-1999-095
surv-1999-116
surv-2000-049
surv-2000-070
surv-2000-101

Due to proprietary issues, the new plots are in png format instead of gif format.  You will 
notice that the Light Attenuation column in the txt files has been replaced with derived-TSM.  
Same is true for the plots.  Also, the new plots have "(v2)" appended to the title at the top 
to distinguish them from the plots they are replacing.

Additional regressions will be developed for the remaining months when time permits.
