N 2 fixation as a dominant new N source in the western tropical South Pacific Ocean (OUTPACE cruise)
Mathieu Caffin,Thierry Moutin,Rachel A. Foster,Pascale Bouruet-Aubertot,Andrea Doglioli,Hugo Berthelot,Hugo Berthelot,Cécile Guieu,Cécile Guieu,Olivier Grosso,Sandra Helias-Nunige,Nathalie Leblond,Audrey Gimenez,Anne Petrenko,Alain de Verneil,Alain de Verneil,Sophie Bonnet +16 more
TL;DR: In this paper, the authors performed nitrogen budgets in the photic layer of three contrasting stations representing different trophic conditions in the western tropical south Pacific (WTSP) Ocean during austral summer conditions.

TL;DR: In this article, surface waters of the western tropical South Pacific (WTSP) were sampled along a longitudinal 4000 km transect during the austral summer (stratified) period (18 February to 3 April 2015) between the Melanesian Archipelago (MA) and the western part of the SP gyre (WGY).
Biogeochemical and biological impacts of diazotroph blooms in a Low Nutrient Low Chlorophyll ecosystem: synthesis from the VAHINE mesocosm experiment (New Caledonia)
Sophie Bonnet,Sophie Bonnet,Melika Baklouti,Audrey Gimenez,Hugo Berthelot,Ilana Berman-Frank +5 more
TL;DR: In this paper, the authors investigated the transfer and export efficiency of diazotroph-derived nitrogen in marine ecosystems and whether the DDN is preferentially and directly exported out of the photic zone, recycled by the microbial loop and/or transferred into larger organisms.
Biogeochemical fluxes and fate of diazotroph-derived nitrogen in the food web after a phosphate enrichment: modeling of the VAHINE mesocosms experiment
TL;DR: The VAHINE mesocosm experiment in the oligotrophic waters of the Noumea lagoon (New Caledonia), where high N2 fixation rates and abundant diazotroph organisms were observed, aimed to assess the role of the nitrogen input through N 2 fixation in carbon production and export as mentioned in this paper.
Community Structure of Tintinnid Ciliates of the Microzooplankton in the South West Pacific Ocean: Comparison of a High Primary Productivity with a Typical Oligotrophic Site
TL;DR: It is found that communities of these plankton grazers in ‘hot spots’ of phytoplankton productivity in oligotrophic systems, although harboring different species, differ little from surrounding oligOTrophic areas in community structure.
