Plankton abundance and biomass at five depths in Lake Simoncouche (Saguenay, Quebec, Canada) during winter 2020-2021

This dataset includes limnological and biological data from 5 depths under the ice of boreal lake Simoncouche during winter 2020-2021, as well as the respective overturns where sampling was conducted on integrated water column. In addition are included data from two long-term under-ice moored multisensors (1.5 m and 6 m depth) recording measurements of temperature, light, specific conductivity and oxygen concentration, for which the daily mid-day values were selected in the file "long_term_rbr". Included information covers zooplankton abundance (zoopl_abund) and biomass (zoopl_biom) per taxa, bacteria, picoplankton, and nanoflagellates abundance and biomass (microbes_abund_biom), and physico-chemical variables (phys_chem_data; long_term_rbr).

本数据集涵盖2020-2021年冬季寒带湖泊西蒙库什（Simoncouche）冰下5个深度的湖沼学与生物学数据，以及对应开展整水柱采样的水体翻转事件相关数据。此外，数据集还包含两台长期冰下锚定多参数传感器（部署深度分别为1.5米与6米）的观测数据，其记录了温度、光照、比电导率与溶解氧浓度，相关的每日正午时刻取值已整理至文件"long_term_rbr"中。本次收录的信息还包括各分类群的浮游动物丰度（zoopl_abund）与生物量（zoopl_biom）、细菌、微微浮游生物与纳米鞭毛虫的丰度及生物量（microbes_abund_biom），以及理化变量数据（phys_chem_data；long_term_rbr）。
