Can we establish from that 30" data causing the problem if the top cells
are centered at 90N or at 89d 59' 45" ? Having a row of (non-uniform)
data centered at 90N seems like a mistake in the data creation to me.

I know the ETOPO2 dataset correctly has top edge at 90N after import,
center of top cells are at 89d 59".
