Not really, as its citing works that aren't canon it doesn't necessarily mean it's like that in the canon. Literally the only major references are 'the Encircling Sea' and all that stuff may have been in unfinished tales but it's just that - unfinished! Basically, that page is a load of rubbish and Ekkaia is just the name for all the seas in Arda.
