ACCESS CTD (Station CB3_P11-W), Line CB3_P11, Station W

These data describe Chlorophyll a, Conductivity, Salinity, Sea Water Density, Sea Water Pressure, Sea Water Turbidity, Temperature: Water Temperature measurements from ACCESS CTD (Station CB3_P11-W), Line CB3_P11, Station W, with measurements made from 2009-09-16T18:47:59Z to 2009-09-16T18:48:01Z. 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)sea_water_practical_salinity (Salinity, 1e-3)sea_water_practical_salinity_qc_agg (Salinity QARTOD Aggregate Quality Flag)sea_water_practical_salinity_qc_tests (Salinity QARTOD Individual Tests)sea_water_density (kg.m-3)sea_water_density_qc_agg (Sea Water Density QARTOD Aggregate Quality Flag)sea_water_density_qc_tests (Sea Water Density QARTOD Individual Tests)sea_water_pressure (decibars)sea_water_pressure_qc_agg (Sea Water Pressure QARTOD Aggregate Quality Flag)...

本数据集记录了搭载于ACCESS的CTD（Conductivity, Temperature, Depth，温盐深剖面仪）在CB3_P11测线W站位（CB3_P11-W站位）采集的实测数据，涵盖海水叶绿素a浓度、电导率、盐度、海水密度、海水压力、海水浊度及水温等指标，测量时段为2009年9月16日18:47:59Z至2009年9月16日18:48:01Z。
加利福尼亚洋流生态系统应用研究计划（Applied California Current Ecosystem Studies, 简称ACCESS）于2004年启动，是由蓝点保护科学（Point Blue Conservation Science）、科德尔班克国家海洋保护区（Cordell Bank National Marine Sanctuary）与大法拉隆国家海洋保护区（Greater Farallones National Marine Sanctuary）联合开展的多学科合作项目。该计划通过为资源管理者、政策制定者及保护合作伙伴提供科学研究支撑，致力于保护加州北部与中部海域的野生生物种群，维护健康的海洋生态系统；同时推动生态系统尺度下的私人与政府海洋科研协调工作，以应对当地紧迫的海洋管理需求。
