RELEASE-2021

This data product contains the quality-controlled, native sampling resolution data from NEON's groundwater chemistry sampling protocol. Subsamples are analyzed at NEON domain headquarters for alkalinity and acid neutralizing capacity (ANC); other subsamples are sent to external facilities for a broad suite of analytes, including dissolved and total nutrients and carbon, cations and anions, and general chemistry. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. Latency: 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. gwc_domainLabData: 60 gwc_externalLabData: 150 gwc_fieldData: 30 gwc_fieldSuperParent: 30 gwc_externalLabSummaryData: 14

本数据产品包含经过质量控制、保留原生采样分辨率的美国国家生态观测站网络（National Ecological Observatory Network, NEON）地下水化学采样规程原始数据。子样本将在NEON领域总部开展碱度与酸中和容量（Acid Neutralizing Capacity, ANC）的分析检测；其余子样本则被送往外部实验室，完成涵盖溶解态与总态营养盐、碳组分、阴阳离子及常规化学指标在内的多类分析物检测。如需了解更多细节，请参阅本数据产品详情网页文档板块中列出的用户指南、采样规程及科学设计方案。
数据发布延迟：针对下载数据包内的各数据表，从野外数据及/或样本采集到正式数据发布的预期耗时（单位：天）如下，详细信息请参阅《数据产品用户指南》。
