THOON was established and continues to be supported with funding from California's Ocean Protection Council and California Sea Grant (CA Prop 68). THOON is deployed seasonally (spring to fall) due west of Trinidad Head in about 75 m of water at Station TH02 along the Trinidad Head Line. The profiling mooring is a wave-powered WireWalker equipped with an RBR sensor package to profile temperature, salinity, chlorophyll, and dissolved oxygen throughout the water column at high temporal resolution (roughly every 8 minutes) and to transmit the data in near-real-time to shore via cellular communications. To measure pH throughout the water column, an experimental ISFET-based pH sensor was integrated into the sensor package, building on recent progress towards configuring the sensor for rapid profiling applications.” Sponsor: California Ocean Protection Council, California Sea Grant Cal Poly Humboldt None https://sensors.ioos.us/#metadata/138079/station information web browser Background Information Background information from the source information pointOfContact Earth Science > Oceans > Salinity/Density > Salinity Earth Science > Oceans > Ocean Chemistry > pH Earth Science > Oceans > Ocean Chemistry > Oxygen Earth Science > Oceans > Ocean Chemistry > Dissolved Gases Earth Science > Oceans > Ocean Chemistry > Chlorophyll theme GCMD Science Keywords Cal Poly Humboldt project time latitude longitude altitude mass_concentration_of_chlorophyll_a_in_sea_water aggregate_quality_flag quality_flag mass_concentration_of_oxygen_in_sea_water aggregate_quality_flag quality_flag sea_water_practical_salinity aggregate_quality_flag quality_flag sea_water_sigma_t aggregate_quality_flag quality_flag sea_water_temperature aggregate_quality_flag quality_flag sea_water_temperature aggregate_quality_flag quality_flag sea_water_ph_reported_on_total_scale aggregate_quality_flag quality_flag theme CF Standard Name Table v72 The data may be used and redistributed for free but is not intended for legal use, since it may contain inaccuracies.
