This is an effect of the process used to generate the polar projections, 
which used a pre-tiled source of data for the oceans from zoom 7 and 
up.  The rectangles are different sizes, so there are gaps between them 
when their corners are reprojected into EPSG:3575.

I intend to reprocess the polar base maps, but since they're not often 
used on the GBIF.org website it's not a high priority.
