Google fails me, or I have failed it; I have no idea how to word this in a search, so I'm asking it here. Below is an image of the Mediterranean Sea. You'll notice how I've highlighted two specific parts of the sea with red boxes. What I need to know is approximately how big of an area those boxes represent, preferably in kilometers. I'm looking for a straight length, not surface area. Also, if anyone could answer the same question about the western half of the Black Sea, that could be helpful too. And finally, are there any islands in these selections? Are they inhabited? I'm looking for a span of sea at least 1000 km in diameter. Somehow, I get the feeling that none of my options are that large.
