Instrument:
Continuous sea surface water monitoring system (MR14-03 - )
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.

After considering the accuracy of the sensors, the significant digit of data was changed as in the following list.
Data Raw (ASCII data) On this web site
Temperature 0.0001 [deg-C] 0.001 [deg-C]
Salinity 0.0001 [PSU] 0.001 [PSU]
Dissolved oxygen 0.01 [umol/kg] 0.1 [umol/kg]
* The unit of the dissolved oxygen was changed from ml/l into umol/kg since MR10-04.

Calibration Information is as follows.
DMO-QCed data are flagged after the data check process shown below:
1) Range check
For details about range set of temperature, salinity and oxygen data, please refer the web site of NODC (National Oceanographic Data Center) from the following link for quality control procedure.
2) Visual check
If an value were extremely out from time-series plot of each variable or were affected by ambient air due to unstable flow of sampled water, it may be put flag "A" which means doubtful value.
This cruise obtained data of fluorescence, turbidity, and total dissolved gas pressure in addition to data of temperature, salinity and dissolved oxygen. Please contact us for usage of those data.
