TL;DR: The North Pacific Ecosystem Model for Understanding Regional Oceanography (NEMURO) as discussed by the authors is a lower trophic level ecosystem model for the North Pacific Ocean, which has eleven state variables: nitrate, ammonium, small and large phytoplankton biomass.
Journal ArticleDOI

TL;DR: The grazing rate estimation indicates that the copepod grazing prevented the formation of an extensive diatom bloom, which was observed in SEEDS, and led to the change to a pico-phytoplankton dominated community towards the end of the experiment.
Journal ArticleDOI
An Ecosystem Model Coupled with Nitrogen-Silicon-Carbon Cycles Applied to Station A7 in the Northwestern Pacific
TL;DR: In this article, a model based on Kishi et al. (2001) has been extended to 15 compartments including silicon and carbon cycles and applied to Station A7 off Hokkaido, Japan, in the Northwestern Pacific.
Journal ArticleDOI
One Dimensional Ecosystem Model Simulation of the Effects of Vertical Dilution by the Winter Mixing on the Spring Diatom Bloom
TL;DR: The deep mixing significantly affects the amplitude of the spring diatom bloom not only by the supply of nutrients but also by the dilution which drastically decreases the grazed pressure.
Journal ArticleDOI
Population dynamics of phytoplankton, heterotrophic bacteria, and viruses during the spring bloom in the western subarctic Pacific
TL;DR: This is the first report on the microbial trophodynamics, including viruses, during the spring diatom bloom in the western subarctic Pacific, and it has become evident that the carotenoid fucoxanthin can serve as a strong indicator of the diatom carbon biomass during the Spring Diatom bloom.
