The Green Edge cruise: following the evolution of the Arctic phytoplankton spring bloom, from ice-covered to open waters

the green edge project was designed to investigate the onset, life and fate of a phytoplankton spring bloom (psb) in the arctic ocean. the lengthening of the ice-free period and the warming of seawater, amongst other factors, have induced major changes in arctic ocean biology over the last decades. because the psb is at the base of the arctic ocean food chain, it is crucial to understand how changes in the arctic environment will affect it. green edge was a large multidisciplinary collaborative project bringing researchers and technicians from 28 different institutions in seven countries, together aiming at understanding these changes and their impacts on the future. the fieldwork for the green edge project took place over two years (2015 and 2016) and was carried out from both an ice camp and a research vessel in the baffin bay, canadian arctic. here, we describe the data set obtained during the research cruise, which took place aboard the canadian coast guard ship (ccgs) amundsen in spring 2016.

绿色边缘项目旨在探究北极海洋中浮游植物春季水华（PSB）的起始、生命周期及其命运。在过去几十年中，由于冰期延长、海水温度升高等因素的影响，北极海洋生物学经历了重大变化。鉴于PSB位于北极海洋食物链的基础位置，深入理解北极环境变化对其影响至关重要。绿色边缘项目是一个大型跨学科合作项目，汇聚了来自七个国家28个不同机构的科研人员和技师，共同致力于探究这些变化及其对未来可能产生的影响。该项目实地考察历时两年（2015年和2016年），在加拿大北极的巴芬湾，既在冰营又从研究船上展开。在此，我们描述了2016年春季在加拿大海岸警卫队船（CCGS）阿蒙森号上进行的科研航次所获得的数据集。
