See Terms and Conditions about constrain of use.
See Terms and Conditions about data citation.
Instrument:
Water sampling system with CTD (30 litters * 24 bottles)
Instrument:
Water sampling system with CTD (12 litters * 36 bottles)
Instrument:
Water sampling system with CTD (12 litters * 12 bottles)
Instrument:
Conductivity temperature depth measurements (CTD)
CTD(Conductivity-Temperature-Depth profiler) is used to observe the vertical profiles of temperature and conductivity.
Usually, this system is operated with multicylinder water sampler.
Observed signal is transmitted from sensor to the operation room on board using wire cable, and electric power is supplied from vessel to sensor.
Details of sensors attached to CTD system for MR06-03 Leg2 cruise are presented in “System”.
The following software, developed and supplied by the Sea-Bird Electronics, Inc., was used in MR06-03 Leg2.
SEASAVE(ver 5.27b) for data acquisition
SEASOFT(ver 5.27b) for data processing
Data presented on this website is averaged over 1db.

(2) Data processing sequence for SEASOFT is as follows;
command function
datcnv Convert raw data to engineering units, and store converted data in file.
alignctd Align data relative to pressure(typically used for conductivity, temperature, and oxygen).
wildedit Mark a data value with badflag to eliminate wild points.
celltm Perform conductivity thermal mass correction.
filter Low-pass filter columns of data.
wfilter Median filter removes spikes of fluorometer data.
section Extract rows of data from file.
loopedit Mark a scan with badflag if scan fails pressure reversal or minimum velocity tests.
derive Calculate oxygen. (with oxygen sensor)
binavg Average data, basing bins on pressure, depth, scan number, or time range.
derive Calculate salinity, density, etc..
split Split data in file into upcast and downcast files.
(3) The time and position presented in the header is at the starting time of cast.
(4) In this cruise, there is extra data (fluorescence intensity, transmittance, distance to bottom) in additional to temperature, salinity, dissolved oxygen that has been opened to the public. Please contact us from "Contact Us" above if necessary.
