Note
----
The :class:`xarray.DataArray` grid doesn't support slice operation, for
Earth seafloor crustal age with resolutions of 5 arc-minutes or higher,
which are stored as smaller tiles.

The registration and coordinate system type of the returned
:class:`xarray.DataArray` grids can be accessed via the GMT accessors
(i.e., ``grid.gmt.registration`` and ``grid.gmt.gtype`` respectively).
However, these properties may be lost after specific grid operations and
need to be set manually before passing the grid further to PyGMT functions.
Refer to :class:`pygmt.GMTDataArrayAccessor` for detailed explanations and
workarounds.
