AbstractThe unicellular cyanobacterium Candidatus Atelocyanobacterium thalassa (UCYN‐A) is a key diazotroph in the global ocean owing to its high N2 fixation rates and wide distribution in marine environments. Nevertheless, little is known about UCYN‐A in oxygen‐deficient zones (ODZs), which may be optimal environments for marine diazotrophy. Therefore, the distribution and diversity of UCYN‐A were studied in two consecutive years under contrasting phases (La Niña vs. El Niño) of El Niño Souther
