Figure 3 – (A) One-fifth of the one-minute binned, uncorrected spectra recorded on day 31 of the cruise. (B) Spectra with only the scattering correction applied. (C) Spectra with scattering and traditional temperature and salinity corrections applied. (D) spectra corrected using Eq. 5\* MERGEFORMAT () and the derived by minimizing Eq. 6\* MERGEFORMAT (). Insets show the red−NIR region where the effects of inaccurate are most apparent. Note the presence of negative in the visible range in (B) and (C).

Figure 4 – (A) Frequency distribution of the measured from the temperatures obtained by interpolating between hourly adjacent measurements. (B) obtained by minimizing Eq. 6\* MERGEFORMAT (). ''prcrng'' is half the difference between the 84-th and 16-th percentiles, which is approximately one standard deviation for normally distributed data.
