Possible error

A reader contacted Wikimedia (ticket:2020021610002882) to suggest that the text of this article states:

The NORSAR link crossed the Atlantic via a satellite link to London, then continued via cable to Norway.

But the diagram suggests that the satellite link was to Norway with a cable to London.

I hope someone can sort out whether the text is correct, and the diagram wrong, or vice versa, or both the reader and I are misreading the diagram.

As the name suggests, NORSAR, as the Norweigian Seismic Array, ostensibly links to that country — although the NORSAR Wikipedia page also states that It was also a connection point for ARPANET to spread to England, and then to the rest of Europe. The first diagram shows this, as the TIP link is shown as a staggard link from SDAC (/\/\/) to NORSAR, then as a straight link (———) from NORSAR to London. If London were directly linked to SDAC, then it would be shown as such in the diagram. The sentence used in the article The NORSAR link crossed the Atlantic via a satellite link to London, then continued via cable to Norway is problematic for two reasons: (a) the wording suggests that the link between London and NORSAR is one way, by using the words then continued via cable to Norway. Nothing in that phrase suggests that the link didn't already originate in Kjeller and continue on to London (as the diagram suggests). (b) The sentence doesn't state where, on the other side of the Atlantic, the link went to. As the English Channel is part and parcel of the Atlantic Ocean, this could be describing London's link to mainland Europe, which is also shown in the diagram. If "crossing the Atlantic" meant from mainland Europe, then the sentence would be correct according to the diagram (admittedly, the term "crossing the Atlantic" is almost exclusively used as meaning from North America to Europe, although going from Europe to South America or even Africa would also, geographically speaking, be "crossing the Atlantic". My point is, the sentence itself is problematic because it uses leymans terms like "crossing the Atlantic" and is not directly referenced. As a compromise, I've placed a speculation inline template next to the sentence. Regards,  Spintendo  13:43, 17 February 2020 (UTC)

Fixed and cited. Source says "data from the NORSAR seismic array were transmitted to the Seismic Data Analysis Center (SDAC) in Virginia via the Nordic satellite station in Tanum, Sweden." Whizz40 (talk) 13:57, 17 February 2020 (UTC)
