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:

本数据产品包含经质量管控的原生采样分辨率数据，此类数据源自美国国家生态观测站网络（NEON）开展的特定深度剖面数据采集工作。深度剖面数据的采集会与水柱内的任意其他采样协议同步开展，例如同步进行浮游植物、浮游动物或地表水化学采样。深度剖面数据包含通过手持探头（handheld probe）在水柱中每0.5米采集的水温、电导率（conductivity）与溶解氧（dissolved oxygen）数据。深度剖面数据仅在湖泊靠近浮标（buoy）的最深区域，或河道浮标的附近区域采集。此类数据不仅可为采样模块提供配套元数据（metadata），还可依据温跃层（thermocline，若存在）确定地表水化学及相关分析物、地表水微生物与浮游植物采样的深度。深度剖面数据全年采集，包括北部站点的冰下采集，每年至少开展12次。如需获取更多详情，请查阅本数据产品详情网页“文档”板块中所列的用户指南、采集规程与科学设计方案。
