中文摘要
鲍威尔和海德沃格尔东部边界流系统,如加州海流系统,浮游生物生物量很高,因为循环过程周期性地迫使营养丰富的深层水进入海洋表面。建议将物理和生物模型联系起来,将中尺度特征(细丝、喷流和涡流)与人口增长、繁殖力和死亡率的空间和人口变化联系起来。这项研究的结果将有助于人们更好地理解底栖动物垂直迁移和水循环如何相互作用来影响重要的CCS浮游动物物种的空间分布和种群成功,如太平洋水蚤、太平洋次生虫和太平洋真水蚤。
英文摘要
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.
