IOOS Glider - ru30-20211020T1316

This project is conducting seasonal deployments to investigate carbonate chemistry and monitor ocean acidification 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 approximately 21 to 30 day deployment out of Tuckerton, NJ will run a cross-shelf transect (along E line) to an offshore waypoint north of Carteret Canyon, then transect SSW to Wilmington Canyon, then NW back to Tuckerton, NJ as the battery pack allows. This glider track will cover Atlantic sea scallop and Atlantic surfclam habitats in the southern MAB. The real-time dataset contains CTD, dissolved oxygen, chlorophyll a, CDOM and optical backscatter measurements. Dissolved oxygen and pH data will be processed post-deployment. This is the third deployment of this glider in 2021.cdm_data_type = TrajectoryProfileVARIABLES:trajectory (Trajectory Name)wmo_idtime (Profile Time, seconds since 1970-01-01T00:00:00Z)latitude (Profile Latitude, degrees_north)longitude (Profile Longitude, degrees_east)profile_idtime_uv (Depth-averaged Time, seconds since 1970-01-01T00:00:00Z)lat_uv (Depth-averaged Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)u (Depth-averaged Eastward Sea Water Velocity, m s-1)v (Depth-averaged Northward Sea Water Velocity, m s-1)latitude_qc (latitude Variable Quality Flag)longitude_qc (longitude Variable Quality Flag)time_qc (time Variable Quality Flag)depth (m)depth_qc (depth Variable Quality Flag)...

本项目开展季节性部署，旨在调查大西洋中部湾（Mid-Atlantic Bight）的碳酸盐化学体系并监测海洋酸化。用于自动观测的海洋滑翔机搭载了集成式深潜型离子敏感场效应晶体管（Ion Sensitive Field Effect Transistor，ISFET）基pH传感器。该pH传感器单元配套搭载滑翔机已有的多款传感器：包括CTD（电导-温度-深度剖面仪）、配置用于同步测量叶绿素荧光与光学后向散射的WETLabs FLBBCD ECO探头，以及用于测量溶解氧的Aanderaa Optode型传感器。
本次部署时长约21至30天，从新泽西州塔克顿出发，沿跨陆架断面（E线）航行至卡特里特峡谷以北的近海航点，随后沿西南偏南（SSW）方向航行至威尔明顿峡谷，最后在电池续航允许的前提下沿西北偏北（NW）方向返回塔克顿。本次滑翔机航迹将覆盖南大西洋中部湾（MAB）的大西洋海扇与北大西洋潜穴蛤栖息地。
本实时数据集包含CTD、溶解氧、叶绿素a、有色溶解有机物（CDOM）及光学后向散射测量数据。溶解氧与pH数据将在部署完成后进行后期处理。本次为该滑翔机2021年的第三次部署。
