LakeBeD-US: Ecology Edition - a benchmark dataset of lake water quality time series and vertical profiles

LakeBeD-US: Ecology Edition is a harmonized lake water quality dataset containing time series and vertical profiles of 21 lakes in the United States monitored by long-term monitoring institutions. These institutions include the North Temperate Lakes Long-Term Ecological Research program (NTL-LTER), Niwot Ridge Long-Term Ecological Research program (NWT-LTER), National Ecological Observatory Network (NEON), and the Carey Lab at Virginia Tech as part of the Virginia Reservoirs Long-Term Research in Environmental Biology (LTREB) site in collaboration with the Western Virginia Water Authority. The data include depth-discrete observations of 17 water quality variables including temperature, dissolved oxygen, chemical properties, Secchi depth, and more. Observations are divided into data collected by automated sensors at a relatively high temporal frequency and manually sampled data at a relatively low temporal frequency. All data were collected in situ. The data are available as Apache Parquet files, and the included R scripts give guidance on how to utilize and query the dataset in R. LakeBeD-US: Ecology Edition is an ecological science-oriented companion to LakeBeD-US: Computer Science Edition. The Computer Science Edition is available on the Hugging Face Hub.

LakeBeD-US：生态学分册（LakeBeD-US: Ecology Edition）是一套标准化整合的湖泊水质数据集，涵盖美国21个湖泊的时间序列与垂直剖面监测数据，相关数据由多家长期监测机构采集。这些机构包括北温带湖泊长期生态研究计划（North Temperate Lakes Long-Term Ecological Research program, NTL-LTER）、尼沃特岭长期生态研究计划（Niwot Ridge Long-Term Ecological Research program, NWT-LTER）、国家生态观测站网络（National Ecological Observatory Network, NEON），以及弗吉尼亚理工大学凯里实验室——该实验室作为弗吉尼亚水库环境生物学长期研究（Long-Term Research in Environmental Biology, LTREB）站点的一部分，与弗吉尼亚西部水务局合作开展监测工作。数据集包含17项水质变量的深度分层观测值，涵盖温度、溶解氧、化学属性、赛氏盘深度（Secchi depth）等指标。观测数据分为两类：一类由自动传感器以相对较高的时间频率采集，另一类为人工采样且时间频率相对较低的数据。所有数据均为原位实地采集所得。该数据集以Apache Parquet格式文件提供，随附的R脚本可指导用户在R语言环境中调用并查询该数据集。LakeBeD-US：生态学分册是面向生态科学研究的配套数据集，其姊妹篇《LakeBeD-US：计算机科学分册》（LakeBeD-US: Computer Science Edition）可在Hugging Face Hub平台获取。
