pH, temperature, salinity, and oxygen time series measurements from the Gulf of Alaska Ecosystem Observatory GEO2 mooring deployed at approximately 32 meter depth in the Gulf of Alaska 2020-2021

This dataset presents a data record of the pH, temperature, salinity, and oxygen from the Gulf of Alaska Ecosystem Observatory. These data are presented both as csv-formatted tabular data and as self-describing netCDF files. The Gulf of Alaska Ecosystem Observatory (GEO2) is a set of subsurface moorings on the Gulf of Alaska shelf that is annually recovered and re-deployed. These data are part of the Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) program. The LTER program is a National Science Foundation–funded network of 28 sites nationwide that focus on the influence of long-term and large-scale phenomenon on ecosystems. Additional funding for sampling is provided by the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOS) via the Gulf Watch Alaska program.本数据集收录了阿拉斯加湾生态观测站（Gulf of Alaska Ecosystem Observatory）获取的pH值、温度、盐度与溶解氧数据记录。该数据集同时提供CSV格式的表格数据与自描述netCDF文件两种形式。阿拉斯加湾生态观测站（Gulf of Alaska Ecosystem Observatory，简称GEO2）由部署于阿拉斯加湾陆架的多套水下锚系设备组成，每年进行回收与重新部署作业。本数据集隶属于北阿拉斯加湾长期生态研究（Northern Gulf of Alaska Long Term Ecological Research，简称NGA LTER）计划。LTER计划是由美国国家科学基金会资助的全国性科研网络，旗下共有28个观测站点，聚焦长期与大尺度现象对生态系统的影响机制。采样工作的额外资助方包括北太平洋研究委员会（North Pacific Research Board，简称NPRB）、阿拉斯加海洋观测系统（Alaska Ocean Observing System，简称AOOS），以及经由海湾观察阿拉斯加项目（Gulf Watch Alaska program）运作的埃克森·瓦尔迪兹溢油赔偿委员会（Exxon Valdez Oil Spill Trustee Council，简称EVOS）。
