Depth profile at specific depths (DP1.20254.001)

This data product contains the quality-controlled, native sampling resolution data from NEON's Depth profile at specific depths data collection. Depth profile data are collected along with any other sampling protocol in the water column (e.g., phytoplankton, zooplankton, or surface water chemistry). Depth profile data include water temperature, conductivity, and dissolved oxygen data collected every 0.5 m through the water column using a handheld probe. Depth profile data are only collected at the deepest location of the lake near the buoy, or near the river buoy. These data not only provide metadata to accompany the sampling modules, but also inform sampling depths based the thermocline, if present, for water chemistry and associated analytes, surface water microbes, and phytoplankton sampling. Depth profiles are collected year-round, including under ice at northern sites, a minimum of 12 times per year. 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.

本数据产品包含经过质量管控的原生采样分辨率数据，采自美国国家生态观测站网络（NEON）的深度剖面特定深度采集数据集。深度剖面数据可与水柱内的各类采样方案同步采集，例如浮游植物、浮游动物或地表水化学采样。深度剖面数据涵盖使用手持探针在水柱中每0.5米采集一次的水温、电导率与溶解氧数据。深度剖面数据仅在湖泊靠近浮标的最深处，或河流浮标附近区域采集。此类数据不仅可为各类采样模块提供配套元数据，还可基于温跃层（若存在），为水化学及相关分析物、地表水微生物与浮游植物采样确定采样深度。深度剖面全年开展采集，涵盖北部站点的冰下采集场景，每年至少采集12次。更多详情请参阅本数据产品详情网页文档部分列出的用户指南、采样规程与科学设计文件。数据延迟说明：下载数据包内各数据表从野外数据和/或样本采集至数据发布的预期时长（单位：天）如下，详细信息请参阅本数据产品用户指南。dep_profileData: 30 dep_profileHeader: 30
