@dabail10 Would you be willing to combine this with a small change on our side? This is needed because NCO requires that warnings not be suppressed, and there is a single warning generated from CICE

CICE-interface/CICE/cicecore/drivers/nuopc/cmeps/ice_prescribed_mod.F90(21): warning #6843: A dummy argument with an explicit INTENT(OUT) declaration is not given an explicit value.   [RC]                                                                                                                           
  subroutine ice_prescribed_init(clock, mesh, rc)

This change resolves that warning and I added the use only statements for ESMF.
