The corrections for the XBT depth biases is provided in the Table
for the probe types Sippican T4, Sippican T7, Sippican T10 and 
Unknown for the years 1968 to 2008. To correct the XBT depths 
obtained using the Hanawa et al. (1995) fall rate equation, 
they must be multiplied by the correction values are provided here
for the corresponding year and probe type.

Hence the depth correction equation

Z=Z0*Zfix
Where Zfix is from the table.
