   Subj: Transfer of National Status and Trends Sediment Toxicity Data Sets

   Doug:   Enclosed, find one (1) box with four (4) diskettes containing a
           total of 18 files of the NS&T sediment toxicity and related embay-
           ment data sets.  Also enclosed are four (4) data reports ( 3 from
           later studies) for use as metadata and additional information.
           Seven (7) of the data sets are replacement for ones previously
           submitted (3/28/96), eleven (11) are new data sets.  Please see 
           information under"Files Sent".  I've indicated which are replacement
           and those that are new data sets.   All of the files are sent as
           MAC EXCEL spreadsheet files and seem to read very nicely on a 
           PC using MS EXCEL 97.
