!> Revision history:
!>
!> July 1997 - deleted final pressure calculation loop (moved to to thermf.f)
!> Apr. 1999 - added calculation of -th3d-
!> Aug. 2000 - convcm: adapted from micom 2.8 to run within hycom 1.0
!> Oct. 1999 - convch: convection of u and v added
!> Oct. 2009 - convcm: MPI bug fix.
!> Oct 2010 - replaced two calls to dsiglocdX with one call at mid-point
!> Aug 2011 - replaced dpold,dpoldm with dpo
!> May 2014 - use land/sea masks (e.g. ip) to skip land
