  abstract = {{D}initrogen ({N}-2) fixation rates were investigated in the euphotic layer of the {B}ismarck and {S}olomon {S}eas using {N}-15(2) incubation assays taking into account both the particulate and the dissolved pools. {A}verage depth-integrated particulate {N}-2 fixation rates were 203 (range 43-399) and 1396 (range 176-3132)mol {N} m(-2) d(-1) in the {B}ismarck and {S}olomon {S}eas, respectively. {I}n both seas, {N}-2 fixation measured in the dissolved pool was similar to particulate {N}-2 fixation, highlighting the potentially substantial underestimation of {N}-2 fixation in oceanic budgets when only particulate {N}-2 fixation is considered. {A}mong the diazotroph phylotypes targeted using quantitative polymerase chain reaction amplification of nif{H} genes, {T}richodesmium was the most abundant. {R}egression analyses suggest that it accounted for the major proportion of {N}-2 fixation. {H}owever, unicellular cyanobacterial and non-cyanobacterial diazotrophs were also occasionally abundant. {T}his study reports high pelagic {N}-2 fixation rates and confirms that the {W}estern {T}ropical {S}outh {P}acific is a hot spot for marine {N}-2 fixation.},
