Dissolved inorganic carbon, total alkalinity, pH, and other variables collected from profile and discrete sample observations using CTD, Niskin bottle, and other instruments from R/V Henry B. Bigelow off the northeastern coast of the United States from 2012-06-02 to 2012-06-13 (NCEI Accession 01389

This archival package contains discrete bottle (CTD profile) data that was collected in the northeastern coast of the United States in 2012. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry resulting in a reduction in pH, a process termed ocean acidification. Studies have demonstrated adverse effects on calcifying organisms, particularly some invertebrates, corals, sea urchins, pteropods, and coccolithophores. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).

本存档数据包涵盖2012年于美国东北海岸采集的离散采水（温盐深，Conductivity Temperature Depth, CTD）剖面数据。人类工业活动导致大气二氧化碳含量持续攀升，正在改变全球海洋碳化学体系，进而造成海水pH值下降，该过程被称为海洋酸化。已有研究证实，海洋酸化会对钙化生物造成不利影响，尤其影响部分无脊椎动物、珊瑚、海胆、翼足类及颗石藻。本数据集的采集工作旨在支持美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）海洋酸化项目（Ocean Acidification Program, OAP）的海岸监测与研究目标。
