8.  creation summary:

	This file contains two 100x116x12 records.  The first is monthly
	SSS from /fs/cgd/data0/yeager/POP_GRIDS/gx3v5.012/PHC2_SALT_gx3v5.nc
	(which is a remapping of /HECHT/POLES/PHC2_SALT.nc onto gx3v5 using
	/fs/cgd/data0/yeager/POP_GRIDS/Initial_Conditions/lev2grid.csh).

	The second record is a remapping of the second 'flxio' record from
 	/fs/cgd/csm/inputdata/ocn/pop/gx3v4/forcing/sfwf_20021217.ieeer8
	onto gx3v5 using /wp/cgd/yeager/SCRIP/remappings/map_gx3v4_to_gx3v5_conserv.nc

	NOTE:  The above conservative remapping generated the following problem
	points for scrip1.4:

	The problem points were deleted from this gx3v4->gx3v5 remapping
	using /fs/cgd/data0/yeager/POP_GRIDS/idl_tools/correct_map_errors.run

	(NOTE: This mapping results in zero flxio in some regions on the
	new gx3v5 grid, such as where the Canadian archipelago has been
	excavated).
