RELEASE-2022

This data product contains the quality-controlled, native sampling resolution data from NEON's aquatic periphyton and phytoplankton collection and field metadata, as well as associated taxonomic, and enumeration data provided by contracted labs. Benthic and water column field samples are collected in wadeable streams, rivers, and lakes three times per year during the growing season. Samples are separated into aliquots for taxonomic analysis at the domain support facility (preserved in glutaraldehyde or Lugol's iodine) for shipment to a external facilities, or filtered onto glass-fiber filters for biomass (ash-free dry mass). For additional details, see the user guide, protocols, science design, and lab SOPs listed in the Documentation section in this data product's details webpage. The expected time from data and/or sample collection in the field to data publication is as follows, for each of the data tables (in days) in the downloaded data package. See the Data Product User Guide for more information. alg_fieldData: 60 alg_biomass: 60 alg_taxonomyProcessed: 210 alg_taxonomyRaw: 210 alg_qualityCheck: 210 alg_archive: 30 alg_biovolumes: 14

本数据产品包含经质量管控的原生采样分辨率数据，源自美国国家生态观测站网络（National Ecological Observatory Network, NEON）的水生周丛藻类与浮游藻类采集项目及野外元数据，同时涵盖签约实验室提供的相关分类学与计数数据。底栖与水柱野外样本于生长季每年在可涉水溪流、河流与湖泊中采集三次。样本被分装为多份等分试样：一部分经戊二醛或鲁戈氏碘液固定后，送至区域支持设施开展分类学分析，再运往外部实验室；另一部分则过滤至玻璃纤维滤膜上，用于生物量（无灰干重）测定。如需获取更多细节，请查阅本数据产品详情网页文档板块中列出的用户指南、实验方案、科学设计及实验室标准操作流程。下载数据包中各数据表从野外采集数据和/或样本至数据公开的预期耗时（单位：天）如下，更多信息请参阅《数据产品用户指南》：藻类野外数据表（alg_fieldData）：60，藻类生物量表（alg_biomass）：60，经处理的藻类分类学数据表（alg_taxonomyProcessed）：210，原始藻类分类学数据表（alg_taxonomyRaw）：210，藻类质量检查表（alg_qualityCheck）：210，藻类归档数据表（alg_archive）：30，藻类生物体积数据表（alg_biovolumes）：14
