IOOS Glider - Integrative Ocean Observing Systems: California Coast Trinidad Head Glider Line - sg686-20251111T1924

The Trinidad Head glider line aims to extend the time series of sustained glider-based measurements off the California that begun in 2014. Seaglider and SGX underwater gliders repeatedly occupy a single section that extends offshore from the continental slope to 40.05N, 129W. Gliders profile from the sea surface to 1000-m depth and back every 6 hours while traversing the line at a speed of roughly 20 km/day. The Trinidad Head line is sampled by a single glider, which is replaced as needed to maintain continuous occupation of the section.cdm_data_type = TrajectoryProfileVARIABLES:conductivity (Sea Water Electrical Conductivity, S.m-1)density (Sea Water Density, kg.m-3)depth (m)instrument_O2 (Aanderaa Optode 4831)instrument_ctd (CTD Metadata, 1)instrument_optodeinstrument_wetlabs (Wetlabs BB2FLIRB2 7513)lat_uv (Depth-averaged Latitude, degrees_north)latitude (Profile Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)longitude (Profile Longitude, degrees_east)platform (Platform Metadata, 1)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)profile_idqartod_conductivity_flat_line_flag (QARTOD Flat Line Test for sea_water_electrical_conductivity, 1)qartod_conductivity_gross_range_flag (QARTOD Gross Range Test for sea_water_electrical_conductivity, 1)qartod_conductivity_primary_flag (QARTOD Primary Flag for sea_water_electrical_conductivity, 1)qartod_conductivity_rate_of_change_flag (QARTOD Rate of Change Test for sea_water_electrical_conductivity, 1)qartod_conductivity_spike_flag (QARTOD Spike Test for sea_water_electrical_conductivity, 1)...
