IOOS Glider - NOAA OAP (Ocean Acidification Program)/IOOS - um_242-20211105T1601

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. The real-time dataset contains CTD, chlorophyll a, CDOM and optical backscatter measurements. Dissolved oxygen and pH data will be processed post-deployment.cdm_data_type = TrajectoryProfileVARIABLES:commanded_alt_time (c_alt_time, sec)commanded_climb_target_depth (c_climb_target_depth, m)commanded_de_oil_vol (c_de_oil_vol, cc)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, S.m-1)crs (http://www.opengis.net/def/crs/EPSG/0/4326)ctd41cp_timestamp (sci_ctd41cp_timestamp, seconds since 1970-01-01T00:00:00Z)density (Sea Water Density, kg.m-3)depth (m)dr_latitude (m_lat, degrees decimal minutes)dr_longitude (m_lon, degrees decimal minutes)...
