Periphyton, seston, and phytoplankton collection (DP1.20166.001)

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.

本数据产品包含经过质量管控、原生采样分辨率的美国国家生态观测站网络（National Ecological Observatory Network，NEON）水生周丛藻类与浮游藻类采集数据、野外元数据，以及签约实验室提供的相关分类学与计数数据。底栖与水体野外样本于生长季在可涉水溪流、河流与湖泊中每年采集三次。样本被分装为若干分样：一部分经戊二醛或卢戈氏碘液固定后，送至区域支持设施开展分类学分析并外运；另一部分则通过玻璃纤维滤膜过滤，用于生物量（无灰干重）测定。如需获取更多详情，请参阅本数据产品详情网页文档板块中列出的用户指南、实验规程、科学设计方案与实验室标准操作流程。
下载的数据包中各数据表从野外数据和/或样本采集至数据公开的预期耗时（单位：天）如下，详见《数据产品用户指南》：
