The timing of spring phytoplankton blooms is crucial to many species that have adapted their development to benefit from the enhanced feeding opportunity they offer. Any change to their timing may affect the productivity of an entire ecosystem. This study explores the relationship between the ocean climate, the timing of the spring bloom and the secondary production on the Newfoundland and Labrador shelf. It is found that over interannual cycles, the ocean climate is significantly correlated with the timing of the bloom and the abundance of Calanus finmarchicus, a key zooplankton species for the ecosystem. It also appears that the spring bloom is initiated by the onset of ocean re-stratification following winter mixing. Understanding how annual variation in climate relates to the timing of the spring bloom and zooplankton abundance, that is, the base of the marine food web, can inform the development of ecosystem-informed models for higher trophic levels.

纽芬兰和拉布拉多大陆架春季浮游植物繁殖时间的物理控制和生态影响

春季浮游植物大量繁殖的时间对于许多物种至关重要，这些物种已经适应了自身的发育，以从它们提供的更多摄食机会中受益。它们的时间安排的任何变化都可能影响整个生态系统的生产力。这项研究探讨了海洋气候、春季开花时间与纽芬兰和拉布拉多大陆架二次生产之间的关系。研究发现，在年际循环中，海洋气候与赤水哲藻的盛开时间和丰度显着相关，生态系统的关键浮游动物物种。春季的水华似乎也是由冬季混合后海洋重新分层的开始引发的。了解气候的年度变化与春季开花时间和浮游动物丰度（即海洋食物网的基础）的关系，可以为开发更高营养级的生态系统模型提供信息。
