Physical oceanography during RV METEOR cruise M196

Physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV METEOR during research cruise M196. The CTD system is comprised of a Seabird SBE911plus including dual respectively redundant sensor and pump packages. The SBE11plus Deck Unit remains on board in a laboratory and supplies on one hand power to the SBE9plus underwater unit, on the other hand data telemetry between the SBE9plus and a measurement PC. The SBE9plus underwater unit itself holds a pressure sensor and is interfacing with dual SEB3 temperature and SBE4 conductivity sensors and a single SBE43 oxygen sensor, as well as two SBE5 pumps to provide a pumped water supply past each sensor. The system also carries an optical FLNTU sensor to measure a combination of back-scattering, turbidity, and chlorophyll-a. To quantify the photo-synthetically active radiation a PAR sensor is installed as well.

物理海洋学数据由RV METEOR船上的Seabird SBE911plus CTD-Rosette系统收集，该系统在M196科研航行期间进行采集。CTD系统由Seabird SBE911plus构成，包括双份各自冗余的传感器和泵组。SBE11plus甲板单元保持于实验室中，一方面为SBE9plus水下单元提供电力，另一方面在SBE9plus与测量用个人电脑之间传输数据遥测。SBE9plus水下单元本身配备有压力传感器，并与双份SEB3温度和SBE4电导率传感器，以及单一SBE43氧气传感器相连接，此外还装备有两个SBE5泵，以便为每个传感器提供泵送水流。系统还携带一种光学FLNTU传感器，用以测量反散射、浑浊度和叶绿素a的复合值。为了量化光合有效辐射，还安装了一个PAR传感器。
