Short summary
This study focuses on the distribution of three heterotrophic prokaryote groups in relation to the environmental conditions met in the western part of NPSG. Our results showed that the high variability between the various heterotrophic prokaryote cluster abundances depend both on the mesoscale structures and the oligotrophic gradient. To the best of our knowledge, this study is the first report of the heterotrophic prokaryotes distribution under La Niña conditions in the western part of NPSG.
