Well fuck. I guess it wasn't the Russians after all.

Edit: Nvm. This article only tells us that four explosions have now been confirmed via seismological data analysis. Nothing else new has been confirmed yet.

Important excerpt:

Other reports in the Scandinavian media have pointed to a cluster of Russian ships, with their identifying transponders turned off, in the vicinity of the blast sites in the days before the explosions

Key points:

in june 2022, three months before the attack, that six members of Ukraine’s special operations forces were going to rent a boat and use a submersible vehicle to dive to the seabed using oxygen and helium for breathing, in order to sabotage the pipeline.

In July (one month later, 2 months before the attack), the UN security council heard investigators had found traces of undersea explosives in samples from a yacht, but that they were unable to reliably establish the identity or motives of those involved or whether it was the work of a specific country.

Full text of that first paragraph:

A leaked US defence document, reported by the Washington Post, showed the CIA had been tipped off by an allied European agency in June 2022, three months before the attack, that six members of Ukraine’s special operations forces were going to rent a boat and use a submersible vehicle to dive to the seabed using oxygen and helium for breathing, in order to sabotage the pipeline. But the leaked US document said the planned operation had been put on hold.

And, of course, that's not the point of the article in the slightest. It's that two additional explosions were identified on top of the one original one.

Anyone know why they use helium too?

[–] [email protected] 9 points 1 year ago

Apparently it's to help deal with how oxygen and nitrogen can both have a bit of a narcotic effect at high pressures. Helium doesn't do this and is generally harmless to breathe so long as you're still getting enough oxygen, so if some or all of the nitrogen is replaced with helium then it can mitigate the problem by reducing the amount of nitrogen you're breathing

This is the best summary I could come up with:


Scientists investigating the attack on the Nord Stream pipelines have revealed key new details of explosions linked to the event, which remains unsolved on its first anniversary.

Researchers in Norway shared with the Guardian seismic evidence of the four explosions, becoming the first national body to publicly confirm the second two detonations, as well as revealing a detailed timeline of events.

Seismologists at Norsar, Norway’s national data centre for the comprehensive nuclear test ban treaty (CTBT), told the Guardian they had so far found a total of four explosions – one south-east of Bornholm and three north-east of the island.

Based in Kjeller, near Oslo, Norsar monitors events across the world including nuclear testing in North Korea, the impact of CO2 storage on the Norwegian continental shelf and conflict zones such as Ukraine.
