The feasibility and enumeration studies have led to the following conclusions: The nitrogen fixation studies should be done in 1973, using acetylene reduction technique with some verification by N15. The denitrification studies should be done with N15 technique. The decision to continue more enumeration sampling of nitrogen transforming bacteria should be based on comparisons of the 1972 enumerations with the chemical budget The pertinent literature is listed in the appendix of the report; the reprints are housed in Dr. Taub's office, 212 Fisheries Center, University of Washington. The enumeration data are presented in the report
