ACCESS CTD (Station D16-B), Line D16, Station B

These data describe Chlorophyll a, Conductivity, Omega Aragonite, Oxygen: Dissolved Oxygen Concentration, Oxygen: Saturation, Salinity, Sea Water Density, Sea Water Pressure, Sea Water Turbidity, Temperature: Water Temperature measurements from ACCESS CTD (Station D16-B), Line D16, Station B, with measurements made from 2018-07-22T16:31:59Z to 2024-05-08T03:13:26Z. The Applied California Current Ecosystem Studies (ACCESS) program was formed in 2004 as a multidisciplinary collaborative between Point Blue Conservation Science, Cordell Bank National Marine Sanctuary and Greater Farallones National Marine Sanctuary. It supports marine wildlife conservation and healthy marine ecosystems in northern and central California through scientific research that informs resource managers, policy makers and conservation partners. ACCESS also works to coordinate private and governmental marine research at an ecosystem scale to address urgent local management needs.cdm_data_type = TimeSeriesProfileVARIABLES:time (seconds since 1970-01-01T00:00:00Z)latitude (degrees_north)longitude (degrees_east)z (Altitude, m)mass_concentration_of_chlorophyll_a_in_sea_water (Chlorophyll a Mass Concentration, microg.L-1)mass_concentration_of_chlorophyll_a_in_sea_water_qc_agg (Chlorophyll a Mass Concentration QARTOD Aggregate Quality Flag)mass_concentration_of_chlorophyll_a_in_sea_water_qc_tests (Chlorophyll a Mass Concentration QARTOD Individual Tests)sea_water_electrical_conductivity (Conductivity, mS.cm-1)sea_water_electrical_conductivity_qc_agg (Conductivity QARTOD Aggregate Quality Flag)sea_water_electrical_conductivity_qc_tests (Conductivity QARTOD Individual Tests)omega_aragonite (1)omega_aragonite_qc_agg (Omega Aragonite QARTOD Aggregate Quality Flag)omega_aragonite_qc_tests (Omega Aragonite QARTOD Individual Tests)mass_concentration_of_oxygen_in_sea_water (Dissolved Oxygen Concentration, mg.L-1)mass_concentration_of_oxygen_in_sea_water_qc_agg (Dissolved Oxygen Concentration QARTOD Aggregate Quality Flag)mass_concentration_of_oxygen_in_sea_water_qc_tests (Dissolved Oxygen Concentration QARTOD Individual Tests)fractional_saturation_of_oxygen_in_sea_water (Oxygen Saturation, %)fractional_saturation_of_oxygen_in_sea_water_qc_agg (Oxygen Saturation QARTOD Aggregate Quality Flag)...
