Cordell Bank Hypoxia Mooring

The mooring was built and deployed by University of California Davis (UCD), Bodega Marine Laboratory (BML) and Greater Farallones and Cordell Bank National Marine Sanctuaries (GFNMS/CBNMS). The hypoxia monitoring buoy is equipped with oceanographic instruments which record dissolved oxygen, temperature, and salinity at Cordell Bank at depths up to 80 meters. Instruments collected time-series mooring data every 10 minutes. Instruments include: Minidot dissolved oxygen loggers (part #7450) with anti-fouling copper kit (part #4405) from Precision Measurement Engineering, Inc; and SBE 37-SM MicroCAT from Sea-bird Scientific. Instruments are situated at depth just above the anchor weight. This data is collected year-round, with few gaps in between (e.g. sensors were flooded, data was corrupted, or mooring was lost). The instruments on the mooring are replaced two to three times a year by staff from UCD BML and GFNMS/CBNMS.cdm_data_type = TimeSeriesVARIABLES:time (seconds since 1970-01-01T00:00:00Z)latitude (degrees_north)longitude (degrees_east)z (Altitude, m)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)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)fractional_saturation_of_oxygen_in_sea_water_qc_tests (Oxygen Saturation 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_temperature (Water Temperature, degree_Celsius)sea_water_temperature_qc_agg (Water Temperature QARTOD Aggregate Quality Flag)sea_water_temperature_qc_tests (Water Temperature QARTOD Individual Tests)station (Cordell Bank Hypoxia Mooring)

本锚定观测系统由加州大学戴维斯分校（University of California Davis, UCD）、博德加海洋实验室（Bodega Marine Laboratory, BML）以及大法拉隆与科德尔班克国家海洋保护区（Greater Farallones and Cordell Bank National Marine Sanctuaries, GFNMS/CBNMS）搭建并部署。
该低氧监测浮标搭载海洋学观测仪器，可在科德尔班克海域最大80米深度处记录溶解氧、海水温度及实用盐度数据。
仪器以10分钟的采样间隔采集时序锚系观测数据，所用设备包括：Precision Measurement Engineering, Inc.生产的Minidot溶解氧记录仪（部件号#7450）搭配防污铜套件（部件号#4405），以及Sea-bird Scientific出品的SBE 37-SM MicroCAT。
所有观测仪器均安装于锚重正上方的深度位置。
本数据集为全年连续采集，仅存在少量间断（如传感器进水、数据损坏或锚系系统丢失等情况）。
加州大学戴维斯分校博德加海洋实验室及大法拉隆与科德尔班克国家海洋保护区的工作人员，每年会对锚系系统上的观测仪器进行2至3次更换维护。
