研究人员提出,测量溶解的氢分子(一种已知的氮酶活性的副产品)有可能为海洋固氮研究打开一扇新的窗口。海洋固氮虽然对海洋碳循环至关重要,也是一个长期研究的主题,但仍然没有充分量化。根据快照同位素速率测量和间接全球地球化学证据的收集,全球海洋固定n2的估计值在100至2亿吨N/年之间(Carpenter & Capone, 2008)。
英文摘要
It is proposed that measurements of dissolved molecular hydrogen, a known byproduct of nitrogenase activity, have the potential to open a new window on the study of marine nitrogen fixation which, although of prime importance to the marine carbon cycle and long a subject of study, remains inadequately quantified. Estimates of global ocean N2-fixation, derived from collections of snapshot isotopic rate measurements and indirect global geochemical evidence, range between 100 and 200Mtonnes N/yr (Carpenter & Capone, 2008).
