Diazotrophy in the Indian Ocean is poorly understood compared to that in the Atlantic and Pacific Oceans. Scientists examined the basin-scale community structure of diazotrophs and their nitrogen fixation activity within the euphotic zone during the northeast monsoon period along about 69°E from 17°N to 20°S in the oligotrophic Indian Ocean, where a shallow nitracline (49-59 m) prevailed widely and the sea surface temperature (SST) was above 25°C.
