Yes, we can imagine this or that, but we don't find it from the article. Of course there is also the issue that no information about Antarctica can be confirmed by citizen journalists as the whole world (US, UK, Russia, China, etc) all agreed to preserve this continent and Antarctica can never even be felt explored by the public. Anyway, Antarctic information is certainly mediated for us.
