The Green Edge initiative: understanding the processes controlling the under-ice Arctic phytoplankton spring bloom

the green edge initiative was developed to investigate the processes controlling the primary productivity and the fate of organic matter produced during the arctic phytoplankton spring bloom (psb) and to determine its role in the ecosystem. two field campaigns were conducted in 2015 and 2016 at an ice camp located on landfast sea ice southeast of qikiqtarjuaq island in baffin bay (67.4797n, 63.7895w). during both expeditions, a large suite of physical, chemical and biological variables was measured beneath a consolidated sea ice cover from the surface to the bottom at 360 m depth to better understand the factors driving the psb. key variables such as temperature, salinity, radiance, irradiance, nutrient concentrations, chlorophyll- concentration, bacteria, phytoplankton and zooplankton abundance and taxonomy, carbon stocks and fluxes were routinely measured at the ice camp. here, we present the results of a joint effort to tidy and standardize the collected data sets that will facilitate their reuse in other arctic studies.

绿色边缘倡议旨在探究调控北极浮游植物春季爆发（PSB）初级生产力和有机物质命运的过程，并确定其在生态系统中的作用。2015年和2016年，在位于巴芬湾（67.4797N，63.7895W）西基克塔鲁亚克岛东南部固定海冰上的冰营进行了两次实地考察。在这两次探险中，对海冰覆盖下从水面到360米深度的底部进行了大量物理、化学和生物变量的测量，以更好地理解驱动PSB的因素。温度、盐度、辐射亮度、辐照度、营养浓度、叶绿素浓度、细菌、浮游植物和浮游动物丰度和分类、碳储存和通量等关键变量在冰营中被常规测量。在此，我们展示了联合整理和标准化收集到的数据集的结果，这将便于在其他北极研究中重复利用。
