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 2021-11-05 to 2021-12-09 (NCEI Accession 0295428)

This dataset contains the trajectory profile data from Slocum glider um_242 from one seasonal deployment (2021-11-05 to 2021-12-09) 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 Monhegan Island.

本数据集包含编号为um_242的斯洛克姆（Slocum）水下滑翔机在2021年11月5日至2021年12月9日的单次季节性布放任务中获取的轨迹剖面数据，该任务旨在缅因湾（Gulf of Maine）海域测量酸碱度（pH）及其他相关海洋参数。该滑翔机搭载了经改装的海鸟电子（Seabird Electronics）温盐深剖面仪（Conductivity Temperature Depth, CTD），其泵吸样品流内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，该滑翔机还配备了WETLabs公司的ECO探头，用于测量叶绿素荧光与光学后向散射，以及Aanderaa公司的Optode型溶解氧传感器以监测溶解氧含量。本次布放作业始于芒特迪瑟特岛（Mount Desert Isle）附近，完成了缅因湾部分深海盆的断面观测，最终在蒙赫根岛（Monhegan Island）附近结束作业。
