pH and other trajectory profile observations made from Slocum glider um_242 in the Gulf of Maine using a Seabird Electronics ISFET-based pH/ctd instrument, from 2023-08-03 to 2023-08-21 (NCEI Accession 0295432)

This dataset contains the trajectory profile data from Slocum glider um_242 from one seasonal deployment (2023-08-03 to 2023-08-21) to measure pH and other parameters in the Gulf of Maine. The glider was equipped with a Seabird Electronics CTD modified to include an Ion Sensitive Field Effect Transistor (ISFET) pH sensor within the pumped sample stream. Also included on this glider were a WETLabs ECO puck measuring chlorophyll fluorescence and optical backscatter, and an Aanderaa Optode for measuring dissolved oxygen. This deployment began near Mount Desert Isle, made transects of some of the deeper basins of Gulf of Maine, and finished near Toothaker Ridge.

本数据集包含斯洛克姆滑翔机（Slocum glider）um_242在一次季节性部署（2023年8月3日至2023年8月21日）期间获取的轨迹剖面数据，该部署旨在缅因湾（Gulf of Maine）测量pH值及其他相关海洋参数。该滑翔机搭载了经改装的赛百德电子（Seabird Electronics）CTD（温盐深仪），在泵送样品流中集成了离子敏感场效应晶体管（Ion Sensitive Field Effect Transistor，ISFET）pH传感器；此外还搭载了WETLabs ECO puck，用于测量叶绿素荧光与光学后向散射信号，以及Aanderaa Optode溶氧传感器，用于测量溶解氧浓度。本次部署的起始点位位于沙漠岛山（Mount Desert Isle）附近，航迹覆盖了缅因湾的部分深盆地海域，最终结束于图塔克岭（Toothaker Ridge）附近。
