Cascade Project at North Temperate Lakes LTER: Zooplankton 1984 - 2007

Zooplankton data from 1984-1995. Sampled approximately weekly with two net hauls through the water column (30 cm diameter net, 80 um mesh). There have been 5 zooplankton counters during this period, so species-level identifications (TAX, below) are not as consistent as those for some of the other datasets. To standardize across counters, I have assigned higher-level taxonomic categories for a few "confusing" taxa; these identifications can be found in the column LLTAX, below. Sampling Frequency: varies Number of sites: 5本数据集为1984年至1995年的浮游动物（Zooplankton）观测数据。采样以约每周一次的频率开展，每次通过水柱进行两次拖网采样，所用采样网具为网径30厘米、网孔80微米的浮游生物网。本研究周期内共有5名浮游动物分类计数人员，因此物种水平的鉴定结果（TAX，见下文）相较于部分其他数据集的一致性稍差。为统一不同计数人员的鉴定结果，已为部分“难以区分的分类单元”分配了高阶分类类别；此类鉴定结果可参见下文的LLTAX列。采样频率：存在波动。采样位点数量：5个
