Instrument:
Continuous sea surface water monitoring system ( - MR10-03 Leg2)
Thermosalinograph measures the following surface parameters continuously.
- temperature
- salinity
- dissolved oxygen
Sea surface water is continuously pumped up at 4.5 meters depth to the sea surface monitoring laboratory and then flowed into each analysis equipment through a steel pipe and a vinyl-chloride pipe.
The flow rate of this system is controlled by some valves. Data are recorded in the personal computer.

Calibration Information is as follows.
(1) Quality control
QCed data were added flag according to the NODC (National Oceanographic Data Center) quality control procedure.
1) The gradient check of adjacent depth data
Please see the site of NODC of the following link for quality control procedure in detail.
In addition, an abnormal value is identified by a visual check, and the data after visual QC is released.
(1) In this cruise, there is extra data (fluorescence intensity, particle size of plankton) in additional to temperature, salinity, dissolved oxygen that has been opened to the public. Please contact us from "Contact Us" above if necessary.
