subroutine plumes_init_vars (myThid)
c-----------------------------------------------------------------------
c  Routine to initialise the plumes state.
c  
c  Input: myThid       - Process number calling this routine
c
c  Notes: 
c   1) For a Cold Start - 
c      This routine takes the initial condition on the dynamics grid
c      and interpolates to the plumes grid to initialize the state
c      variables.
c   2) For a Restart, read the plumes pickup file
c
c Calls: dyn2plume (x2)
