Instrument:
Continuous sea surface water monitoring system (MR10-04 Leg1 - MR14-02 )
1. Missing of the position data (latitude and longitude) was linearly interpolated.
2. Data whose difference from the median of 3 data points was more than the threshold (0.1 degrees C for temperature and 0.5 for salinity) was replaced by the median.
3. Median filter with a window of 3 data points was applied to the fluorometer data.
4. Hamming filter with a window of 15 data points was applied to the RINKO and fluorometer data.
5. Salinity and oxygen data were corrected by using sampled data as follows.
  Corrected Salinity = c0 + c1*S + c2*day
  Corrected Oxygen = d0 + d1*O + d2*T + d3*day
  where S is uncorrected salinity, O is uncorrected dissolved oxygen, day is days from the first data point and T is temperautre.
     c0 = 2.495641869668417e-2
     c1 = 0.9998358907784815
     c2 = -4.544638082863379e-5
     d0 = -15.6236
     d1 = 0.9952655
     d2 = 0.419058
     d3 = -0.1879829
6. Chlorophyll-a was estimated from the fluorometer data by using sampled data as follows.
  Estimated chlorophyll-a = e0 + e1*Fl (for latitude <= 60 degrees N)
                  = e0 + e2*Fl (for latitude >= 61 degrees N)
                  = f1*(e0 + e1*Fl) + f2*(e0 + e2*Fl) (for 60 degrees N < latitude< 61 degrees N)
  where Fl is fluorescence.
     e0 = -4.97353598e-2
     e1 = 5.976125195e-2
     e2 = 0.16483869226
     f1 = 1 - (latitude - 60)
     f2 = 1 - f1
