Russia is running GPS-jamming machines in St Petersburg and Kaliningrad, affecting aviation and sometimes shipping around Baltic Sea.
Some of my most appreciated work has been localizing these machines in time, space and volume.
Here's a rundown of previous geo-work, reversed chronological order.

21 years ago a single submarine of Swedish Navy sneaked past the extensive anti-submarine shields and sank air craft carrier USS Ronald Reagan in an exercise.
Sweden has since refined the stealth properties of the Gotland-class submarines and a newer class is under construction.

Swedish Radio program Gräns did an interview with commander Paula Wallenburg, top brass of Swedish submarines, guardian of Gotland depths.
She was also part of the crew that sank Nimitz-class carrier USS Ronald Reagan in an exercise in 2005.
Worth a listen!

The US commander in chief has famously claimed that Greenland waters are teeming with Russian and Chinese vessels.
According to AIS data this is bollocks to speak European.
There are 8 Chinese and 0 Russian vessels in US waters, none in Greenland.

It is extremely unlikely that a grouping of 6 cable breaks in a week are explained by common causes.
A lot of cables break each year, and any one might be from a benign cause. But not this many.

There is an estimated 1 in 10k - 100k years chance that all 8 of the Nov 2024 - Jan 2025 Baltic Sea cable breaks are coincidental.
Background data is hard to get by but no matter which real data or reasonable assumption one picks it is extremely unlikely all 8 of them are explained by chance.

Impressive fast work. By the time anyone even properly noticed (on New Year people aren't really following news), the ship was already detained in a Finnish harbour.
A number of images from the FITBURG operation have been released by the Police and FBG, including showing both fast-roping from a FBG H215 Super Puma and an FDF NH90 low over the deck.

Updated map of cable breaks between Sweden and Estonia, based on press release from Estonian ministry for digital affairs.
The details are murky and partly incoherent and I have asked Swedish authorities for clarification.
Whats clear: there are several breaks on one cable.

What would winter holidays be without a ship from Russia damaging a comms cable? Huh!
Small cargo ship FITBURG (Russia to Israel) was helo-boarded by Finnish authorities after being found with anchor chain in water and suspected of damaging an Elisa-cable.

Baltic Fleet is getting a new missile carrier.
This takes total (naval) surface Kalibr cruise missile capacity to 40 barrels. Not counting submarine, land and air assets.
40 is more than totals fired during the largest attacks on Ukraine or the capacity in Black Sea in 2022*
