The temporal dynamics of phytoplankton growth and activity have large impacts on fluxes of
matter and energy, yet obtaining in situ metabolic measurements of sufficient resolution for …

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 …

Trichodesmium, a major colonial cyanobacterial nitrogen fixer, forms large blooms in NO 3-
depleted tropical oceans and enhances CO 2 sequestration by the ocean due to its ability to …

Prochlorococcus and Synechococcus are the two dominant picocyanobacteria in the low-
nutrient surface waters of the subtropical ocean, but the basis for their coexistence has not …

Seasonal drawdown of dissolved inorganic carbon (DIC) in the subtropical upper ocean
makes a significant contribution to net community production (NCP) globally. Although NCP …

Seasonal changes in abundances of Trichodesmium spp. and unicellular cyanobacterial
phylotype groups A and B in the northern South China Sea (SCS) and upstream Kuroshio …

Phosphate monoesterase and diesterase activities were measured with soluble reactive
phosphorus (SRP) and labile and total dissolved organic phosphorus (DOP) concentrations …

We investigated the composition and distribution of diazotrophs in waters of the Kuroshio,
the “hot spot” of nitrogen fixation in the Pacific Ocean, as well as in adjacent waters and the …

The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll
concentrations in which new production is generally considered to be supported by upward …

Labile dissolved phosphoric esters act as important phosphorus sources for microorganisms
in the low‐phosphate oligotrophic ocean. Despite the significant role of labile dissolved …
