 - Temperature
  Coefficients of primary temperature correction: correct_tmp_pri_MR1405_p490.txt
    Coefficients of dependencies for pressure (Pcor) and time (Tcor) and offset were calculated from the data > 490dbar.
  corrCTDTMP = CTDTMP - (Pcor * CTDPRS + Tcor * Sumdate + offset)
  (Sumdate is assumed to be elapsed days from the sensor calibration date)

 - Salinity
    Coefficients of primary conductivity correction: correct_cnd_pri_MR1405_t.txt
    Coefficients of dependencies for pressure (Pcor), conductivity (Ccor), conductivity * pressure (CPcor) and time (Tcor) and offset were calculated from the data, the standerd deviation of which was < 0.00002.   
  corrCTDCND = CTDCND - (Pcor * CTDPRS + Ccor * CTDCND + CPcor * CTDCND * CTDPRS + Tcor * Sumdate + offset)
    (Sumdate is assumed to be elapsed days from the time of the first observation at Sta. 001, Cast 1 (001M001), when the CTD was at the bottom.)

 - Dissolved oxygen (RINKO III)
  Time variables and correction coefficients of primary RINKO III: correct_rnk_pri_MR1405_t.txt
  (Sumdate is assumed to be integrated days during the sensor was switched on)

 - Dissolved oxygen (SBE43)
  Coefficients of primary SBE43 correction: correct_o43_pri_MR1405.txt
    First, we calculated gradients of up cast dissolved oxygen profiles from the bottle data. Then, we weighted the gradients and calculated correction coefficients for the dissolved oxygen based on SBE_application note 64-2. The corrected dissolved oxygen was estimated from the coefficients as follows.
    corrCTDOXY = (soc + cof1) * (CTDOXV + voffset + cof2) * (1.0 + ((A1 + cof3) * CTDTEMP) + ((B1 + cof4) * CTDTEMP^2) + ((C1 + cof5) * CTDTEMP^3)) * saturation * exp((E1 + cof6) * CTDPRS / (CTDTEMP + 273.15))

 - Fluorescence
  Coefficients of secondary fluorescence correction: correct_fl_sec_MR1405_w.txt
  We linearly correlated the fluorescence with the bottle data obtained from the Welschmeyer method. The data used for the calculation were sampled from mid night to 5 a.m. (LST). For the calculation, shallow station data, 002M001, 017M001, and 001M002, were excluded.
  corrCTDFL = slope * CTDFL + offset

 - Light transmission
  Time variable of light transmission: correct_xms_MR1405.txt
    Vdark was an average of CTD pre-casts for all stations.
    Vref was calculated from a slope and offset of temporal variation using the data within 3σ for all stations.
    Vref offset was set to be a value not to exceed 100% for the light transmission and fall below 0 for the coefficient of beam attenuation, when they were calculated from the above-mentioned slope.
  Vdark = 0.0012
    Vref = -0.000532 (slope) * sumdate + 4.6111728 (offset) + 0.0072011
    (Sumdate is assumed to be elapsed days from the time of the first observation at Sta. 001, Cast 1 (001M001), when the CTD was at the bottom.)

 - PAR
  offset = -0.046
