SBCLTER: Ocean: Currents and Biogeochemistry: Moored CTD and ADCP Data at Arroyo Quemado Reef (ARQ), ongoing since 2004

ADCP (Currents), CTD (Hydrography) and Optics data (Fluorescence, Beam Attenuation and Volume Scattering Function) were collected at Arroyo Quemado Reef in the Santa Barbara Channel (site ID: ARQ). Data have been interpolated to a 20 minute interval. ADCP data are binned at a 1.0 meter interval, measured as height from the bottom to a maximum of 16 bins. All bins may not be filled, and in some cases, data from bins technically above the surface are included. VSF data are available at angles, 100, 125 and 150 degrees. CTD parameters include Pressure, Temperature, Conductivity, Salinity, Density and Fluorescence. The CTD array is located approximately 4.5 meters from the surface, and there are additional temperature thermistors near the CTD array, at the bottom, and mid way between these two.

本数据集采集自圣巴巴拉海峡（Santa Barbara Channel）阿尔罗约·克马多礁（Arroyo Quemado Reef，站点编号：ARQ），包含声学多普勒流速剖面仪（ADCP，Acoustic Doppler Current Profiler）海流数据、温盐深仪（CTD，Conductivity-Temperature-Depth）水文数据，以及荧光、光束衰减系数与体散射函数（Volume Scattering Function, VSF）三类光学数据。所有数据已被插值为20分钟的时间间隔。ADCP数据以1.0米为间隔进行分层分箱，分箱高度以海底为基准向上测算，最多包含16个分箱。并非所有分箱均有有效数据，且部分场景下会纳入理论上位于海面之上的分箱数据。体散射函数数据可获取的观测角度为100°、125°与150°。CTD测量参数涵盖压强、温度、电导率、盐度、密度及荧光。CTD传感器阵列的安装位置距海面约4.5米；此外在该阵列附近、海底以及二者之间的中途位置，还部署了额外的温度热敏电阻。
