Biological dinitrogen (N 2 ) fixation, the energetically expensive conversion of N gas to ammonia, plays an essential role in balancing nitrogen budget ocean. Accumulating studies show detectable fixation rates below euphotic zone various marine systems, revealing new insights fixation.

Although this approach does not allow accurate quantification rates, our data suggest yet with heterogeneous signals A compilation ocean further reveals such heterogeneity has also been elsewhere, unveiling ubiquitous Thus, call for more observations constrain budgets understand underlying mechanism heterogeneity.
