ACCESS CTD (Station 11-M), Line 11, Station M

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 11-M), Line 11, Station M, with measurements made from 2014-09-24T19:04:00Z to 2023-05-06T21:48:01Z. 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)...

本数据集记录了取自第11号线M站位（Station 11-M）的应用加利福尼亚海流生态系统研究（Applied California Current Ecosystem Studies，以下简称ACCESS）项目的CTD（温盐深仪）所获取的多项海水观测数据，观测参数涵盖叶绿素a、电导率、文石饱和度、溶解氧浓度、氧饱和度、盐度、海水密度、海水压力、海水浊度及水温等，观测时段为2014年9月24日19:04:00 UTC至2023年5月6日21:48:01 UTC。
应用加利福尼亚海流生态系统研究（ACCESS）计划于2004年启动，是由Point Blue保护科学研究所、科德尔班克国家海洋保护区以及大法拉隆国家海洋保护区开展的多学科协同合作项目。该计划通过为资源管理者、政策制定者与保护合作伙伴提供科学研究支撑，致力于加州北部与中部海域的野生生物保护及健康海洋生态系统维护。同时，ACCESS还致力于协调私营与政府部门开展生态系统尺度的海洋研究，以应对紧迫的本地管理需求。
