Surface water DIC, total alkalinity, and pH for the October 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 October 11-14, 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10月11日至14日，研究人员于阿尔塔马哈河（Altamaha River）、多博伊湾（Doboy Sound）、萨佩洛河（Sapelo River）以及达普林河（Duplin River，马什兰丁附近锚站）采集表层水样，用于检测总溶解无机碳（total dissolved inorganic carbon, DIC）、总碱度（total alkalinity, TAlk）与pH值。总溶解无机碳采用定制自动化DIC分析仪进行测定；总碱度通过Gran滴定法（Gran titration）确定；各站位表层水的pH值使用玻璃电极（glass electrode）在船上现场测定。本研究为GCE海洋监测计划的组成部分，后续将定期重复开展。
