资源简介:
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 Sandy Hook, NJ will run cross-shelf transects zig-zagging southward and ultimately coming back inshore along E line for a planned recovery out of Tuckerton, NJ as the battery pack allows. This glider track will cover Atlantic sea scallop and Atlantic surfclam habitats in the 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 first deployment of this glider in 2022.cdm_data_type = TrajectoryProfileVARIABLES:commanded_alt_time (c_alt_time, sec)commanded_ballast_pumped (c_ballast_pumped, cc)commanded_climb_target_depth (c_climb_target_depth, m)commanded_dive_target_depth (c_dive_target_depth, m)commanded_fin (c_fin, rad)commanded_heading (c_heading, rad)commanded_science_send_all (c_science_send_all, bool)commanded_thruster_on (c_thruster_on, %)commanded_weight_drop (c_weight_drop, bool)commanded_wpt_lat (c_wpt_lat, lat)commanded_wpt_lon (c_wpt_lon, lon)commanded_wpt_x_lmc (c_wpt_x_lmc, m)commanded_wpt_y_lmc (c_wpt_y_lmc, m)conductivity (Sea Water Electrical Conductivity)crs (http://www.opengis.net/def/crs/EPSG/0/4326)density (Sea Water Density)...

本项目通过季节性布放,旨在研究中大西洋湾的碳酸盐化学特征并监测海洋酸化状况。
自动化观测所用的滑翔机集成了深水型的离子敏感场效应晶体管(ISFET)pH传感器。
该pH传感器单元还辅以滑翔机已有的其他传感器,包括温盐深仪(CTD)、用于同步叶绿素荧光与光学后向散射测量的WETLabs FLBBCD ECO传感器探头,以及用于溶解氧测量的Aanderaa Optode传感器。
本次布放从新泽西州桑迪胡克出发,持续约21至30天,滑翔机将沿跨陆架断面向南之字形航行,最终在电池允许的情况下沿E线返回近岸,并计划在新泽西州塔克顿回收。
滑翔机的航行轨迹将覆盖中大西洋湾内大西洋扇贝和大西洋浪蛤的栖息地。
实时数据集包含温盐深仪(CTD)、溶解氧、叶绿素a、有色溶解有机物(CDOM)及光学后向散射的观测数据。溶解氧与pH数据将在布放结束后进行处理。
本次布放是该滑翔机2022年的首次任务。
