英文摘要
Using the^<15> N_2 tracer method and high-sensitivity stable nitrogen isotopic composition analytical systems, we determined N2 fixation rates for ocean samples by dividing them into particulate and filtrate fractions. While N_2 fixation in the filtrate fraction had been ignored in previous studies, we found a significant N_2 fixation rates in the filtrate fraction in our study.
