Dissolved inorganic carbon, pH and other variables measured from laboratory experiment studies from an experimental carbonate exposure system from 2013-12-09 to 2014-01-31 (NODC Accession 0123317)

This archival package contains the carbon chemistry measurements of a laboratory experiment study to understand the effects of ocean acidification on winter flounders. To address the goals of the NOAA Ocean Acidification Program (OA), the James J. Howard Laboratory constructed an OA experimental system to conduct OA experiments on commercially important species native to Atlantic waters of the NE U.S. The species of interest exhibit a broad range of ecological and life-history types from entirely marine to entirely estuarine. In order to conduct OA experiments on several different species, the required experimental system was able to mimic both estuarine and oceanic conditions. This system was designed to produce 5 pCO2 concentrations above an ambient pCO2 treatment and 5 temperature regimes. The system is also capable of manipulating dissolved oxygen, salinity, and other biogeochemicals common to a benthic habitat. The analytical laboratory conducts analysis according to the guidelines developed by the ocean acidification subcommittee of the Ocean Carbon and Biogeochemistry Program. When followed correctly, these guidelines should produce data with a high degree of accuracy and precision.

本存档数据集包包含一项旨在探究海洋酸化对冬季鲽鱼影响的实验室实验的碳化学测量数据。为达成美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）海洋酸化（Ocean Acidification, OA）项目的研究目标，詹姆斯·J·霍华德实验室搭建了一套OA实验系统，用于在美国东北部大西洋海域本土的经济物种上开展海洋酸化相关实验。本次研究关注的物种涵盖了从纯海洋到纯河口的多样生态与生活史类型。为在多个不同物种上开展海洋酸化实验，该实验系统需能够同时模拟河口与海洋两种环境条件。该系统被设计为可设置5组高于环境二氧化碳分压（partial pressure of carbon dioxide, pCO₂）处理组的pCO₂浓度，以及5种温度调控方案。该系统还可对底栖生境常见的溶解氧、盐度及其他生物地球化学参数进行精准调控。分析实验室严格遵循海洋碳与生物地球化学项目下属海洋酸化分委员会制定的分析规范开展检测工作。若严格遵循该规范开展实验，所得数据将具备极高的准确度与精密度。
