Ocean acidification alters the oceanic carbonate system, increasing potential for ecological, economic, and cultural losses. Historically, productive coastal oceans lack vertically resolved high‐resolution carbonate system measurements on time scales relevant to organism ecology and life history. The recent development of a deep ion‐sensitive field‐effect transistor (ISFET)‐based pH sensor system integrated into a Slocum glider has provided a platform for achieving high‐resolution carbonate system profiles. From May 2018 to November 2019, seasonal deployments of the pH glider were conducted in the central Mid‐Atlantic Bight. Simultaneous measurements from the glider's pH and salinity sensors enabled the derivation of total alkalinity and calculation of other carbonate system parameters including aragonite saturation state. Carbonate system parameters were then mapped against other variables, such as temperature, dissolved oxygen, and chlorophyll, over space and time. The seasonal dynamics of carbonate chemistry presented here provide a baseline to begin identifying drivers of acidification in this vital economic zone.

大西洋中部地区季节性碳酸盐化学动力学的自主观测

海洋酸化改变了海洋碳酸盐系统，增加了生态，经济和文化损失的可能性。从历史上看，生产性沿海海洋缺乏与生物生态学和生命史有关的时间尺度上垂直解析的高分辨率碳酸盐系统测量值。集成在Slocum滑行器中的基于深离子敏感场效应晶体管（ISFET）的pH传感器系统的最新开发为实现高分辨率碳酸盐系统轮廓提供了一个平台。从2018年5月到2019年11月，在中大西洋中部进行了pH滑翔机的季节性部署。通过滑翔机的pH和盐度传感器的同时测量，可以得出总碱度并计算其他碳酸盐系统参数，包括文石饱和状态。然后将碳酸盐系统参数与其他变量（例如温度，溶解氧和叶绿素）在空间和时间上的关系进行映射。此处介绍的碳酸盐化学的季节性动态提供了一个基准，可以开始确定该重要经济区的酸化驱动因素。
