Trajectory profile data from glider SBU01-04, including pH, deployed in the Mid-Atlantic Bight, North Atlantic Ocean from 2021-05-13 to 2021-06-14 (NCEI Accession 0293515)

This dataset contains the trajectory profile data from glider SBU01-04 from one seasonal deployment to investigate conditions in the Middle Atlantic Bight including the monitoring of ocean acidification. The glider used for the automated observation includes an integrated deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. The pH sensor unit is complemented with existing glider sensors including a CTD, a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. This deployment was launched south of Shinnecock Bay, NY and thence ran across the shelf, then SW to a NW section up toward NY City and was recovered off Point Pleasant, NJ. This delayed mode, high-resolution post-processed dataset contains CTD, chlorophyll a, dissolved oxygen and pH data.

本数据集包含海洋滑翔机SBU01-04在一次季节性布放任务中获取的轨迹剖面数据，该任务旨在调查大西洋中部湾（Middle Atlantic Bight）的海洋环境状况，其中涵盖海洋酸化监测内容。本次布放所使用的自动化观测海洋滑翔机，搭载了一款适配深海额定工况的集成式离子敏感场效应晶体管（Ion Sensitive Field Effect Transistor，ISFET）基pH传感器。该pH传感器单元搭配了滑翔机自带的多款配套传感器，包括温盐深剖面仪（Conductivity-Temperature-Depth，CTD）、一款用于同步开展叶绿素荧光与光学后向散射测量的WETLabs FLBBCD ECO探头，以及Aanderaa品牌的光极溶解氧传感器（Optode）。本次布放作业从纽约州辛内科特湾以南海域起航，随后横跨大陆架，再向西南航行至朝向纽约市的西北海域区块，最终在新泽西州普莱森特角外海完成回收。本数据集为延迟模式高分辨率后处理数据集，包含温盐深、叶绿素a、溶解氧及pH相关观测数据。
