Oh, Welcome aboard. Hope you enjoy the Forum.
No doubt from where you are it may appear that ‘the two sources of data are so inconsequential’. I can assure you that here in Scotland they are in fact VERY consequential. Something that you will not be aware of is ‘The Scottish Adjacent Waters Boundary Order’ in 1999. This went through Westminster on the ‘nod’. It removed 6000 square miles of the North Sea from Scottish Waters into English Waters.
Thanks for the welcome.
