Reprocessed from the file provided by Andrew Bernard (Seabird) following ADMT18. This file is accessible at http://doi.org/10.17882/54520 calib eq 1 for nitrate The sensor returns UV_INTENSITY_DARK_NITRATE and UV_INTENSITY_NITRATE(Ntrans), a subset of continuous pixels of UV_INTENSITY_NITRATE(N), N = 1 to 256. The Ntrans indices span the interval [PIXEL_START, PIXEL_END] subset of the original array (1 to 256). Thus Ntrans(i) refers to pixel N = (PIXEL_START+i-1). PIXEL_START and PIXEL_END are defined from calibration data so that the [PIXEL_START, PIXEL_END] interval is the smallest interval of pixels that correspond to the [217 nm, 250 nm] interval of wavelengths. Only a subset of the [PIXEL_START, PIXEL_END] interval is processed to compute nitrate concentration. This subset is defined as the [PIXEL_FIT_START, PIXEL_FIT_END] interval which is the smallest interval of pixels that correspond to the [217 nm, 240 nm] interval of wavelengths (thus PIXEL_FIT_START = PIXEL_START). In the following equations the data are computed for each pixel R = PIXEL_FIT_START to PIXEL_FIT_END; ABSORBANCE_SW(R)=-log10[(UV_INTENSITY_NITRATE(R)-UV_INTENSITY_DARK_NITRATE)/UV_INTENSITY_REF_NITRATE(R)]; F(R,T)=(A+B*T)*exp[(C+D*T)*(OPTICAL_WAVELENGTH_UV(R)-OPTICAL_WAVELENGTH_OFFSET)]; E_SWA_INSITU(R)=E_SWA_NITRATE(R)*F(R,TEMP)/F(R,TEMP_CAL_NITRATE); ABSORBANCE_COR_NITRATE(R)=ABSORBANCE_SW(R)-(E_SWA_INSITU(R)*PSAL)*[1-(0.026*PRES/1000)]; Perform a multilinear regression to get MOLAR_NITRATE with estimated ABSORBANCE_COR_NITRATE(R) with ABSORBANCE_COR_NITRATE(R)=BASELINE_INTERCEPT+BASELINE_SLOPE*OPTICAL_WAVELENGTH_UV(R)+MOLAR_NITRATE*E_NITRATE(R); NITRATE=MOLAR_NITRATE/rho, where rho is the potential density [kg/L] calculated from CTD data. calib coef for nitrate n/a calib eq 1 for voltage vslope*cnts+voff calib coef for voltage VSLOPE=0.0042; VOFF=1.4967; calib eq 1 for current cslope*cnts+coff calib coef for current VSLOPE=1.1638; VOFF=-2.6618; calib eq 1 for vacuum vacslope*cnts+vacoff calib coef for vacuum VACSLOPE=0.293; VACOFF=-29.767; ======================================== conductivity calibration date 20 05 2018 temperature calibration date 20 05 2018 pressure calibration date 22 05 2018 oxygen calibration date 08 03 2018 mcoms calibration date 10 05 2017 suna calibration date 16 05 2018 float manufacturer SBE float serial number 0935 PI WEI FAN program name CHINA ARGO PROJECT principal investigator address ZJU,ZHEJIANG originating country CHINA float deployer JIANNAN CAI float deployer address XMU, XIAMEN deployment type R/V deployment platform TAN KAH KEE deployment cruise id CARBON-Fe-2020 profile at deployment n/a nominal drift pressure [dbar] 1000 cycles for drift pressure 1 nominal profile pressure [dbar] 2000 cycles for profile pressure 1 Profile Sampling Method continuous pump type 260ml conductivity sensor type SBE41CP_V5.3.1 conductivity sensor accuracy 0.005 conductivity sensor resolution 0.001 conductivity sensor manufacturer SBE conductivity sensor serial number 10754 temperature sensor type SBE41CP_V5.3.1 temperature sensor accuracy 0.002 temperature sensor resolution 0.001 temperature sensor manufacturer SBE temperature sensor serial number 10754 pressure sensor type DRUCK_2900PSIA pressure sensor accuracy 2.0 pressure sensor resolution 0.1 pressure sensor manufacturer DRUCK pressure sensor serial number 10733403 oxygen sensor type SBE63_OPTODE oxygen sensor manufacturer SBE oxygen sensor serial number 1930 oxygen sensor accuracy 3.0 oxygen sensor resolution 0.2 chlorophyll sensor type MCOMS_FLBBCD chlorophyll sensor manufacturer WETLABS chlorophyll sensor serial number 0154 chlorophyll sensor accuracy 0.08 chlorophyll sensor resolution 0.025 chlorophyll sensor excit wavelength 470 chlorophyll sensor emission wavelength 695 backscattering sensor type MCOMS_FLBBCD backscattering sensor manufacturer WETLABS backscattering sensor serial number 0154 backscattering sensor accuracy -999.9 backscattering sensor resolution -999.9 backscattering sensor wavelength 700 backscattering sensor angle 124 backscattering sensor pressure offset 0.1 cdom sensor type MCOMS_FLBBCD cdom sensor manufacturer WETLABS cdom sensor serial number 0154 cdom sensor accuracy -999.9 cdom sensor resolution -999.9 cdom sensor excitation wavelength 370 cdom sensor emission wavelength 460 nitrate sensor type SUNA_V2 nitrate sensor manufacturer SATLANTIC nitrate sensor serial number 1160 nitrate sensor accuracy 2 nitrate sensor resolution 0.01 nitrate sensor pressure offset 1.5 nitrate calibration file SNA1160B.cal nitrate pixel start 38 nitrate pixel end 79 nitrate pixel fit start 38 nitrate pixel fit end 66 battery type Alkaline and lithium initial battery voltage [volt] 15.1 ROM version BGCi_SUNA_ICE 190411 Board serial number 1151 Board version N1 comment n/a
