Conductivity temperature depth measurements (CTD)
Please mention that this cruise was conducted under the Arctic Challenge for Sustainability (ArCS) Project, which was funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT).
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 MR17-05C cruise are presented in “System”.
The following software, developed and supplied by the Sea-Bird Electronics, Inc., was used in MR17-05C.
SEASAVE(ver 7.23.2) for data acquisition
SEASOFT(ver 7.23.2) for data processing

- Temperature
Coefficients of primary temperature correction: correct_tmp_pri_MR1705C_p390.txt
Coefficients of dependencies for pressure (Pcor) and Offset were calculated from the data > 390dbar.
Timecor is assumed to be elapsed days from the sensor calibration date.
When there are two or more water samples in the same layer, the first data is used.
corCTDTMP1 = CTDTMP1 - (Pcor * CTDPRS + Timecor * Sumdate + Offset)
- Salinity
Coefficients of primary conductivity correction: correct_cnd_pri_MR1704_P2.txt
Coefficients of conductivity (Ccor), pressure (Pcor), conductivity * pressure (PCcor), pressure squared (P2cor), and Offset were calculated from the data.
It is not included Timecor calculated to be elapsed days from the time of the first observation.
corCTDCND1 = CTDCND1 - (Ccor * CTDCND1 + Pcor * CTDPRS + PCcor * CTDPRS * CTDCND1 + P2cor * (CTDPRS2) + Offset)
- Dissolved oxygen (RINKO III)
Coefficients of primary RINKO III correction: rinkooutconf_pri_rnkt_8_t_01.txt
The time variable uses the sumday of MR1705C_scanmax.txt calculated from the operating time.
Coefficients were calculated from data in which the standard deviation of the dissolved oxygen voltage of each bottle data is less than 0.01.
Stern-Volmer equation
ksv = c0 + (c1 * CTDTMP1) + (c2 * CTDTMP12)
tau0 = 1 + (c3 * CTDTMP1)
tau = c4 + (c5 * CTDOXV1) + (c6 * sumday) + (c7 * sumday * CTDOXV1)
rinoxy = ((tau0 / tau)conf - 1) / ksv
pressure compensate
ox = (1 + cp * CTDPRS / 1000) * rinoxy
ts = log((298.15 - CTDTMP1) / (273.15 + CTDTMP1))
Calculation of the oxygen solubility was used coefficients calculated by Uchida (2016) from the data of Benson and Krause (1992) by Garcia and Gordon (1984).
B0 = -6.24523e-3
B1 = -7.37614e-3
B2 = -1.03410e-2
B3 = -8.17083e-3
C0 = -4.88682e-7
factt = exp(s * (B0 + B1 * ts + B2 * ts2 + B3 * ts3) + C0 * CTDSAL12);
Garcia and Gordon (1992)
ox = ox * factt;
- Light transmission
Coefficients of light transmission correction: xmissoutconf_MR1705C.txt
The time variable uses the sumday of MR1705C_scanmax.txt calculated from the operating time.
The coefficient is calculated from Vref of high-pressure cast from 390db and further from data less than 3 times the standard deviation of Vref.
Vref = c0 + c1 * sumday
- Fluorescence
Coefficients of primary fluorescence correction: Fl_pri_MR1705C_w1.txt
Coefficients of secondary fluorescence correction: Fl_sec_MR1705C_w1.txt
Coefficients were calculated from the cast time from 20:00 to 04:00 (LST).
corrCTDFL = slope * CTDFL - offset
- PAR
Coefficients of PAR: offset = -0.102
- Nitrate
Coefficients of Deep SUNA correction: correct_suna_MR1705C_ntr_all.txt
The time variable uses the Sumdate calculated from the operating time of SUNA.
corCTDNTR = CTDNTR - (NTRcor * CTDNTR + Timecor * Sumdate + Offset)
