Problems with IDW in Arctic

I have a number of points mapped correctly in the Arctic, but I have problems when running spatial analyst (specifically IDW).  Best I can tell, it does not allow for cross-polar interaction, and there also appears to be some sort of seam that prevents linking across the International Date Line.  Is there a way to correct this problem?  What is the source?

Here is an image of the map in question:
