Phytoplankton in Upper Willamette Reservoirs Dataset

Phytoplankton samples were collected from 5 upper Willamette Basin reservoirs in variable months during years 2013-2016 and 2019. Samples were collected from Blue River Reservoir, Cougar Reservoir, Fall Creek Reservoir, Lookout Point Reservoir, and Hills Creek Reservoir. The phytoplankton were identified and enumerated by Jim Sweet at Aquatic Analysts. Density and biovolume were calculated for each phytoplankton species identified per sample collected. This dataset also includes environmental parameters corresponding to sample collection date or the week preceding sample collection.
Research context: This research was conducted to determine spatial and temporal phytoplankton diversity and bloom timing in the upper Willamette Reservoirs. Cyanobacteria are of particular concern as some species can produce toxins that are harmful to wildlife and humans. Thus, understanding the phytoplankton species present in these reservoirs and their general bloom times is of critical importance.

2013年至2016年及2019年期间，于不同月份从威拉米特河上游盆地(Willamette Basin)的5座水库采集浮游植物(Phytoplankton)样本。本次采集覆盖的水库包括蓝河水库(Blue River Reservoir)、库加尔水库(Cougar Reservoir)、秋溪水库(Fall Creek Reservoir)、瞭望点水库(Lookout Point Reservoir)与希尔溪水库(Hills Creek Reservoir)。浮游植物的物种鉴定与计数工作由Aquatic Analysts公司的吉姆·斯威特(Jim Sweet)完成。针对每份采集样本中鉴定出的浮游植物物种，分别计算其密度与生物体积(biovolume)。本数据集还涵盖了与样本采集当日或采集前一周相关的环境参数。
研究背景：本研究旨在明确威拉米特河上游水库中浮游植物的时空分布多样性与水华暴发时间。蓝藻门(Cyanobacteria)尤其值得关注，因为部分蓝藻物种可产生危害野生动物与人类健康的毒素。因此，明晰这些水库中存在的浮游植物物种及其大致水华暴发时间，具有至关重要的意义。
