Surface water DIC, total alkalinity, and pH for the March 2001 Georgia Coastal Ecosystems LTER oceanographic survey

Surface water samples for total dissolved inorganic carbon (DIC), total alkalinity (TAlk), and pH were collected from the Altamaha River, Doboy Sound, Sapelo River and the Duplin River (anchor station near Marsh Landing) during March 19-21, 2001. DIC was measured using a custom automated DIC analyzer. Total alkalinity was determined by Gran titration. pH of surface water at stations was measured on board using a glass electrode. This study was part of the GCE oceanographic monitoring program, and will be repeated periodically.2001年3月19日至21日，研究人员从阿尔塔马哈河（Altamaha River）、多博伊海湾（Doboy Sound）、萨佩洛河（Sapelo River）以及杜普林河（Duplin River，湿地登陆码头附近的锚定调查站位）采集了用于测定总溶解无机碳（total dissolved inorganic carbon, DIC）、总碱度（total alkalinity, TAlk）与pH值的地表水样本。总溶解无机碳采用定制自动化总溶解无机碳分析仪进行测定。总碱度通过格兰氏滴定法（Gran titration）确定。各调查站位的地表水pH值采用玻璃电极在科考船上现场测定。本研究为GCE海洋监测计划的组成部分，将定期重复开展。
