Ocean pH, alkalinity, salinity, dissolved oxygen, and temperature timeseries of nearshore environments in Kachemak Bay, 2018-2021

These data consist of carbonate chemistry data from four sensor arrays from 2018-2021 in Kachemak Bay, Alaska. The data were collected from four separate regions within Kachemak Bay: Seldovia, Jakolof Bay, Bear Cove, and Homer Spit. Moored SeaFET sensors detected pH, temperature, salinity, and O2 data. Following sensor deployment, the data were downloaded and processed as described in the Process Steps section of the Methods in this metadata file.本数据集涵盖2018年至2021年间于美国阿拉斯加州卡奇马克湾（Kachemak Bay）部署的四组传感器阵列采集的碳酸盐化学数据。数据采集自卡奇马克湾内的四个独立区域：塞尔多维亚（Seldovia）、雅科洛夫湾（Jakolof Bay）、贝尔湾（Bear Cove）以及荷马斯皮特（Homer Spit）。系泊式SeaFET传感器可采集pH值、温度、盐度及溶解氧（O₂）数据。传感器部署完成后，按照本元数据文件中方法章节的《处理步骤》小节所述流程，完成数据的下载与处理工作。
