Floating in the water, with a lot of skin already removed suggesting the whale has been dead for a while. Gulls and fulmars eating it.

...long lower jaw - could be gray whale?
I thought the gray whale was a Pacific animal? I've just read the one was found in 2010 off Israel, but even so I doubt it would be one of them.
...often strip lower jaw from carcass (even still alive whales) - so you may well be right.
