Juneau stream chemistry and discharge for calculation of inorganic carbon flux

This data publication contains tabular stream sampling data collected from five streams located in five independent watersheds. Streamwater samples were taken along the Juneau, Alaska road system from the following streams: Cowee Creek, Fish Creek, Herbert River, Mendenhall River, and Peterson Creek. Water samples were collected intermittently, from weekly to monthly, from 2015 through 2020. Data provided include streamwater temperature, pH, and alkalinity. Daily stream discharge measurements recorded between 2015 and 2020 (continuity of measurements vary across the streams) are also provided for all sites except the Mendenhall River.
The goal of collecting these data was to provide a long-term record of stream chemical constituents and streamwater flow to model watershed chemical behavior and freshwater element flux from the watersheds.
These data were published on 06/13/2023. Minor metadata updates, including citation updates, were made on 01/06/2025.

本数据集发布内容包含采自5个独立流域内5条溪流的表格化溪流采样数据。采样工作沿阿拉斯加州朱诺市的公路路网开展，涉及以下溪流：考伊溪（Cowee Creek）、菲什溪（Fish Creek）、赫伯特河（Herbert River）、门登霍尔河（Mendenhall River）以及彼得森溪（Peterson Creek）。水样采集周期为间歇性采样，频率介于每周至每月之间，采集时段为2015年至2020年。本次发布的数据涵盖溪流水温、pH值以及碱度。除门登霍尔河外，其余所有采样点均提供了2015年至2020年间的每日溪流流量观测数据（各溪流的观测连续性存在差异）。

本数据集的采集目标是提供溪流化学组分与溪流径流的长期观测记录，以用于模拟流域化学行为及流域内淡水元素通量。

本数据集于2023年6月13日正式发布，并于2025年1月6日完成了包括参考文献更新在内的小幅元数据修订。
