Can you rasterize the file in Illustrator and export or unembed the result?

In order to solve this, please show the whole picture.

If we do not even know what kinds of objects interact, nobody will be able to help.

Here is a full picture. 

You can't see the line here because the file is big (120x80cm) and the line is only 1px wide (I guess). It's located above Greenland

Thank you. I assume that the background is a pixel image?

What about those coast lines? Did you use raster based effects, such as inner glow on them?

 

In that case the line could be a result of transparency flattening stitching
