We examined the trans-Pacific zonal variation in N2 fixation activity on 23°N in summer along with environmental parameters that potentially influence diazotrophy. Dissolved inorganic iron (DFe) was consistently low (<0.4 nM) throughout the transect. The atmospheric dust iron (dust-Fe) flux increased westward, whereas phosphate and labile phosphoric monoesters in the surface decreased westward. N2 fixation varied between 34.6 and 298 μmol-N m−2 d−1 and was high (>200 μmol-N m−2 d−1) in the central area (150–180°W). N2 fixation rates significantly increased with dust-Fe input only in the western area (137–180°E), whereas the contribution of DFe diffused from below the euphotic zone was often larger in the eastern area (120–170°W). N2 fixation was considerably low in the phosphate-depleted western area despite the excess amount of iron relative to phosphate, and it increased with the labile phosphoric monoesters stock. These indicated that N2 fixation was primarily limited by phosphorus in the western area, though this activity also increased with iron supply from dust, likely due to phosphorus-iron co-limitation. In contrast, in the phosphorus-repleted eastern area, iron supplied from dust and below the euphotic zone appeared to limit N2 fixation. Overall, N2 fixation in the subtropical North Pacific was likely limited by zonally different factors relating to iron and phosphorus availability.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American
