2)YEAR:  1996
3)PI:  Merryl Alber
4)OTHERS:  Edward Sheppard,   Jim Sullivan,   Katy Austin
5)BRIEF DESCRIPTION OF DATA FILE: Bacterial uptake of 3-H
  leucine.
6)KEYWORDS:  Bacterial  Production
7)RESEARCH LOCATION: LMER 3 Longitudinal Survey, St. Marys
  River.
8)EXPERIMENTAL DESIGNS AND METHODS: Production was calculated
  based on uptake of 20nM 3-H leucine.
9)NOTES AND COMMENTS; Surface & Bottom samples correspond to
  uppermost & lowermost CTD cast depths.
  Elmar stations taken from small boat at distances up
  stream where salinity was 0. No Cast data on these
  sites, cast noted as 999 on data file.

11)CALCULATIONS:
   a. change in DPM=(average scint count (live)-scint count
      (killed))
   b. change in DPM (from Above) per liter per day x 
      (4.545 E-7 nmol/Ci)/(# Ci in isotope)
