Description: 
Conversion of 15N supplied as ammonium to 15N-labeled nitrite plus nitrate in ~48 hr incubations at ~0 oC. NAN = "Not a Number" = no data. Calculation used substrate and in situ nitrate plus nitrite concentration data from samples collected on the cruise. If data for a specific station or depth were not available, water mass averages were substituted. Negative values are obtained if the final d15N of the NOx pool is lower than the measured natural abundance. Precision and relative standard deviations (RSD; ((standard deviation/mean)*100)) estimated from Monte Carlo simulations (10,000 trials) using average values of variables are 2.2 nmol L-1 d-1, or 15.3% of the calculated rate.
