Continuous plankton recorder zooplankton and phytoplankton data, North Pacific Ocean: 1997, 2000-2009, 2012

The data were collected to describe the plankton populations of the North Pacific and to monitor their distribution and abundance over multiple years. The data include abundances of phytoplankton and zooplankton taxa retained by the Continuous Plankton Recorder which collected plankton samples as it was towed behind a merchant ship on a great circle transect from Vancouver, Canada to Japan. Several transects were occupied during 1997, and 2000-2009. 2009 data are also from a transect from Juan de Fuca Strait to Cook Inlet. The samples each represent 18.5km of tow and have been processed according to routine CPR protocols as directed by the Sir Alister Hardy Foundation for Ocean Science (SAHFOS) which operates and maintains the CPR survey. The midpoint of each sample is allocated a position and time based on information on deployment and recovery times from the ship's log.

1997 and 2000 - 2007 data were provided from archives of the Exxon Valdex Oil Spill Trustee Council. 2008 - 2009 data were provided by the North Pacific Research Board. 2012 data was provided by the PI Sonia Batten.

本数据集的采集目标为描述北太平洋浮游生物种群，并对其多年间的分布与丰度变化开展长期监测。数据集涵盖了经连续浮游生物记录仪（Continuous Plankton Recorder, CPR）捕获的浮游植物与浮游动物类群丰度数据；该记录仪被拖曳于商船船尾，沿从加拿大温哥华至日本的大圆航线采集浮游生物样本。1997年以及2000年至2009年间共完成多条该类航线的采样作业；其中2009年的部分采样数据同样来自胡安·德富卡海峡至库克湾的航线。每份样本对应18.5千米的拖曳航程，其处理流程严格遵循由负责运营与维护连续浮游生物记录仪调查项目的阿利斯泰尔·哈迪海洋科学基金会（Sir Alister Hardy Foundation for Ocean Science, SAHFOS）制定的标准操作规程。每份样本的中点位置与采样时间，均依据船舶航海日志中的部署与回收时间信息进行标定。

1997年与2000年至2007年的数据集由埃克森·瓦尔迪兹溢油事故受托人委员会（Exxon Valdex Oil Spill Trustee Council）的档案库提供；2008年至2009年的数据由北太平洋研究委员会（North Pacific Research Board）提供；2012年的数据则由项目首席研究员（Principal Investigator, PI）索尼娅·巴滕（Sonia Batten）提供。
