IOOS Glider - Collaborative Research: Developing a profiling glider pH sensor for high resolution coastal ocean acidification monitoring - ru30-20180705T1825

This project integrated a deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor, the Deep ISFET pH, into a Slocum Webb G2 glider. The pH sensor unit is complemented with existing glider sensors including a CTD, a WETLabs BB2FL ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. This approximately 60-day deployment is from Georges Bank to Atlantic City, NJ.cdm_data_type = TrajectoryProfileVARIABLES:conductivity (Sea Water Electrical Conductivity, S.m-1)conductivity_qc (conductivity Quality Flag)density (Sea Water Density, kg.m-3)density_qc (density Quality Flag)depth (m)depth_qc (depth Quality Flag)instrument_ctd (CTD Metadata, 1)lat_qc (lat Quality Flag)lat_uv (Depth-averaged Latitude, degrees_north)lat_uv_qc (lat_uv Quality Flag)latitude (Profile Latitude, degrees_north)lon_qc (lon Quality Flag)lon_uv (Depth-averaged Longitude, degrees_east)lon_uv_qc (lon_uv Quality Flag)longitude (Profile Longitude, degrees_east)precise_lat (Precise Latitude, degrees_north)precise_lon (Precise Longitude, degrees_east)precise_time (seconds since 1970-01-01T00:00:00Z)pressure (Sea Water Pressure, decibars)pressure_qc (pressure Quality Flag)profile_idprofile_lat_qc (profile_lat Quality Flag)...
