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 Gordon Gunter off the northeastern coast of the United States from 2013-06-09 to 2013-06-23 (NCEI Accession 0137723)

This archival package contains discrete bottle (CTD profile) data that was collected in the northeastern coast of the United States in 2013. 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).

本存档套件包含2013年于美国东北海岸采集的离散采水（CTD剖面）数据。人类工业活动引发的大气二氧化碳浓度持续升高，正改变全球海洋碳化学体系，导致海水pH值下降，这一过程被称为海洋酸化（ocean acidification）。现有研究已证实，海洋酸化会对钙化生物造成不利影响，其中尤以部分无脊椎动物、珊瑚、海胆、翼足类（pteropods）及颗石藻（coccolithophores）为甚。本数据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。
