Study on marine ecosystem responses to global environmental variation using the continuous plankton monitoring system

通过国际合作，我们利用浮游生物连续记录仪（CPR）和2001-2014年存档的浮游生物数据集对北太平洋亚北极地区进行了生态系统监测。研究了北太平洋年代际涛动（PDO）与低营养层生态系统时空变化的关系。通过对浮游生物群落结构的分析，揭示了与pdo相关的季节和/或年际物理环境（如海温和垂直水体混合）变化对浮游植物季节性和浮游动物群落大小结构的影响机制。我们还参与成立了全球心肺复苏调查联盟（GACS），该联盟在北大西洋、南大洋等多个地区开展心肺复苏调查。通过GACS的活动，我们在全球范围内扩展了CPR网络，使我们能够进行全球长期海洋生态系统变化的比较。

Through International collaboration, we conducted ecosystem monitoring over subarctic North Pacific using Continuous Plankton Recorder (CPR) and archived plankton data set for 2001-2014. We studied the link between North Pacific Decadal Oscillation (PDO) and spatio-temporal variation of the lower torophic level ecosystem. Our analysis on plankton community structure revealed the mechanism how PDO-related seasonal and/or interannual variations in physical environments, such as sea temperature and vertical water mixing, significantly influenced timing of phytoplankton seasonality and size structure of zooplankton community. We also contributed to the establishment of Global Alliance of CPR Survey (GACS), which are operating CPR survey in various areas including North Atlantic, Southern Ocean, etc. Through the activities of GACS, we expanded the CPR network world wide to enable us to conduct global comparison of long-term marine ecosystem change.
