Trajectory profile data from glider ru30, including pH, total alkalinity, and aragonite saturation state, deployed by Rutgers, the State University of New Jersey in the Mid-Atlantic Bight from 2021-07-16 to 2021-08-20 (NCEI Accession 0281781)

This dataset contains the trajectory profile data from glider ru30 from one seasonal deployment (2021-07-16 to 2021-08-20) to investigate carbonate chemistry and monitor ocean acidification seasonally in the Mid-Atlantic Bight. 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 sensor failed upon deployment). This deployment out of Tuckerton, NJ ran a cross-shelf transect (along E line) to an offshore waypoint north of Carteret Canyon, then transected SSW to Wilmington Canyon, then NW back to Tuckerton, NJ. This glider track covered Atlantic sea scallop and Atlantic surfclam habitats in the southern MAB. This delayed mode, high-resolution post-processed dataset contains CTD, chlorophyll a, and pH data. Dissolved oxygen measurements are not included in this dataset because the sensor failed upon deployment.

本数据集收录了ru30型海洋滑翔机于2021年7月16日至2021年8月20日的单次季节性部署期间获取的轨迹剖面数据，旨在研究大西洋中部海湾（Mid-Atlantic Bight）的碳酸盐化学特征，并开展该海域的海洋酸化季节性监测。本次自动观测所用的ru30型海洋滑翔机搭载了集成式深海级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其他传感器：包括温盐深剖面仪（Conductivity, Temperature, Depth, CTD）、用于同步测量叶绿素荧光与光学后向散射的WETLabs FLBBCD ECO采样模块，以及用于测量溶解氧的Aanderaa Optode传感器（该传感器在部署时即发生故障）。本次部署从新泽西州塔克顿港出发，先沿E线完成跨陆架断面观测，抵达卡特里特峡谷以北的近海航点，随后沿西南偏南方向横穿至威尔明顿峡谷，再沿西北方向返回新泽西州塔克顿港。该滑翔机的观测航迹覆盖了大西洋中部海湾南部海域的大西洋扇贝（Atlantic sea scallop）与大西洋潜鸟蛤（Atlantic surfclam）栖息生境。本延时模式高分辨率后处理数据集包含温盐深剖面、叶绿素a以及pH观测数据。由于部署时溶解氧传感器即发生故障，本数据集未收录溶解氧观测数据。
