Powell and Haidvogel Eastern boundary currents systems, like the California Current System, have a high plankton biomass because circulation processes periodically force deep, nutrient-rich water to the ocean surface. Linkage of physical and biological models is proposed to relate mesoscale features (filaments, jets, and eddies) to spatial and demographic shifts in population growth, fecundity and mortality. The results of this research should improve the understanding of how diel vertical migration and water circulation interact to affect the spatial distribution and population success of important CCS zooplankton species such as Calanus pacificus, Metridia pacifica and Euphausia pacifica.

鲍威尔和海德福格尔 东部边界洋流系统，如加州洋流系统，具有较高的浮游生物量，因为循环过程周期性地迫使深层营养丰富的水到达海洋表面。 提出物理和生物模型的联系，将中尺度特征（细丝、喷流和漩涡）与人口增长、生育力和死亡率的空间和人口变化联系起来。 本研究的结果应提高昼夜垂直迁移和水循环的相互作用，影响空间分布和人口成功的重要CCS浮游动物物种，如哲水蚤太平洋，Metridia pacifica和太平洋磷虾的理解。
