2018 - 2019 Centre for Environment, Fisheries & Aquaculture Science (Cefas) SmartBuoy Marine Observational Network - UK Waters Phytoplankton Data 2018-2019

This dataset consists of analysed phytoplankton data from the years 2018-2019 inclusive collected in UK waters from the SmartBuoy moorings at Dowsing, WestGabbard2, Warp and Liverpool Bay using WMS and EDU automated water samplers. SmartBuoys consist of a 4 meter tall stainless steel frame with a fibreglass toroid for buoyancy. Instruments are attached at a nominal 1 meter depth to the frame. The water samplers collect into pre-spiked bags containing acidified Lugols Iodine on a pre-determined cycle over the course of a deployment. As of the beginning of this data set water samples have been taken using a CTD rosette on mooring turnarounds in case of buoy failure, reducing the issue of data gaps Following recovery these samples were analysed for a full community of phytoplankton species using the Utermohl method on high-power inverted microscopes. Phytoplankton cell counts are abundance values reported in Cells per Litre.本数据集包含2018年至2019年（含首尾两年）英国海域的经分析浮游植物数据，相关数据采集自部署于多塞宁（Dowsing）、西加巴德2号（WestGabbard2）、沃普（Warp）以及利物浦湾的SmartBuoy锚定浮标，采样采用WMS与EDU自动化水采样器完成。SmartBuoy浮标系统由高4米的不锈钢框架构成，搭配玻璃钢浮筒提供浮力，仪器以标称1米的水深固定于框架之上。水采样器将按照预设周期，在浮标部署期间将水样收集至预先装有酸化卢戈氏碘液（Lugols Iodine）的采样袋中。截至本数据集起始之时，当浮标出现故障时，工作人员会在锚标回收维护周期中使用CTD采水器阵列（CTD rosette）采集水样，以此减少数据缺失情况。浮标回收后，研究人员采用乌特莫尔法（Utermohl method）在高倍倒置显微镜下对浮游植物全群落物种进行分析。浮游植物细胞计数以每升细胞数（Cells per Litre）作为丰度单位进行报告。
