Sound Velocity is calculated using SST from the SBE48 and Salinity from the SBE45. It is calculated using the
http://search.cpan.org/~troxel/Physics-Water-SoundSpeed-0.92/lib/Physics/Water/SoundSpeed.pm.

For January through November 2013, sound speed was calculated using a pressure of 1 MPa, which was incorrect. This has been changed
to .05 MPa going forward from November 2013.
