Application of updated corrections to original XBT data

The temperature and depth corrections for the XBT probe types T4/T6, T7/deep blue and T5 are calculated as follows.

Temperature corrections

T(corrected) = T(xbt) - thermal_bias

The values of thermal bias for T7/DB, T4/T6, and T5 are provided in table 1, table 2, and table 3 respectively.

Depth corrections

Z(corrected) = Z(xbt) * stretch_factor

The stretch values for T7/DB and T4/T6 at 1m depth interval is provided in table 4, table 5, and table 6 respectively.

The temperature and depth corrections for the XBT probe types T10 are calculated as follows.

Temperature corrections

T(corrected) = T(xbt) - thermal_bias

Depth corrections

Z(corrected) = Z(xbt) - depth_bias

Where, depth_bias = -1* (coeff1+coeff2*Z(xbt))

The values of coeff1, coeff2 and thermal_bias for T10 probe are provided in table 7.
