Marine carbonate system discrete profile data from the Gulf of Alaska (GAK) Seward Line cruises between 2008 and 2017 (NCEI Accession 0277034)

This dataset includes chemical data from discrete samples and accompanying physical data from a profiling CTD collected along the GAK Seward Line cruises in the Gulf of Alaska from 2008 to 2017. These data include water temperature, salinity, dissolved oxygen, dissolved inorganic carbon (DIC), total alkalinity (TA), and nutrients (nitrate, nitrite, phosphate, and silicate). The cruise was funded by the North Pacific Research Board (NPRB), the National Oceanic and Atmospheric Administration (NOAA), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOSTC). The carbon data were collected and analyzed by personnel at the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). The CTD operations on the cruise were managed by personnel from the College of Fisheries and Ocean Sciences (CFOS) at UAF. The nutrient data were analyzed by personnel from the CFOS at UAF or the Pacific Marine Environmental Laboratory (PMEL). Cruises were biannual and titled with the ship code (i.e., TX), the season (S = Spring and F = Fall), and the year (i.e., 08-17).

本数据集汇聚了来自离散样本的化学数据，以及沿阿拉斯加湾GAK Seward Line航线在2008至2017年间采集的物理数据。这些数据涵盖了水温、盐度、溶解氧、溶解无机碳（DIC）、总碱度（TA）以及营养物质（硝酸盐、亚硝酸盐、磷酸盐和硅酸盐）。此次航次由北极太平洋研究委员会（NPRB）、国家海洋和大气管理局（NOAA）、阿拉斯加海洋观测系统（AOOS）以及埃克森瓦尔迪兹油轮泄漏信托委员会（EVOSTC）资助。碳数据由阿拉斯加大学费尔班克斯分校（UAF）海洋酸化研究中心（OARC）的员工收集和分析。CTD操作由UAF渔业与海洋科学学院（CFOS）的员工负责管理。营养物质数据由UAF的CFOS或太平洋海洋环境实验室（PMEL）的员工进行分析。航次为双年度进行，并以船码（例如，TX）、季节（S代表春季，F代表秋季）和年份（例如，08-17）命名。
