Determination of nanomolar levels of nutrients in seawater
Abstract Nutrients (phosphate, nitrate, nitrite, ammonium and silicate) exert strong controls
on oceanic primary productivity. In oligotrophic areas, which cover approximately 40% of the …

Nitrification and its influence on biogeochemical cycles from the equatorial Pacific to the Arctic Ocean
We examined nitrification in the euphotic zone, its impact on the nitrogen cycles, and the
controlling factors along a 7500 km transect from the equatorial Pacific Ocean to the Arctic …

Heterotrophic bacteria as major nitrogen fixers in the euphotic zone of the Indian Ocean
T Shiozaki, M Ijichi, T Kodama… - Global …, 2014 - Wiley Online Library
Abstract Diazotrophy in the Indian Ocean is poorly understood compared to that in the
Atlantic and Pacific Oceans. We first examined the basin‐scale community structure of …

Why is Trichodesmium abundant in the Kuroshio?
The genus Trichodesmium is recognized as an abundant and major diazotroph in the
Kuroshio, but the reason for this remains unclear. The present study investigated the …
