Discrete CO2-System Measurements in the Chesapeake Bay Mainstem between 2016 and 2018

These are discrete observations of total dissolved inorganic carbon (DIC) and alkalinity (TA), and associated computed CO2-system parameters, from samples collected throughout the Chesapeake Bay mainstem between 2016 and 2018. Samples were collected on board the R/V Kerhin in Maryland and the R/V Fay Slover in Virginia at a subset of fixed stations in collaboration with the Chesapeake Bay Water Quality Monitoring Program. Samples were analyzed following standard procedures at the Virginia Institute of Marine Science. The DIC and TA data were then used to compute the remaining CO2-system parameters (pH, CO2 partial pressure (pCO2), and carbonate saturation state). A detailed description of sample collection and analytical methods is given Friedman et al., 2019.

本数据集收录了2016年至2018年间在切萨皮克湾主干道所采集的离散观测数据，包括总溶解无机碳（DIC）和碱度（TA），以及相应的二氧化碳系统参数计算结果。采样工作于马里兰州的R/V Kerhin号和弗吉尼亚州的R/V Fay Slover号上完成，采样地点为与切萨皮克湾水质监测计划合作选定的一组固定站点。样品分析遵循弗吉尼亚海洋科学研究所的标准程序。随后，利用DIC和TA数据计算出剩余的二氧化碳系统参数（pH值、二氧化碳分压（pCO2）及碳酸盐饱和度）。有关样品采集和分析方法的详细信息，可参阅Friedman等人于2019年的相关研究。
