An almost mandatory entertaining article, whenever topics about cables, ocean floor, submarines come up: https://www.wired.com/1996/12/ffglass/ "Mother Earth, Mother Board" (stories about laying undersea cable and the history of wiring the Earth up" (or unpaywalled: https://archive.is/ICkHe )

Related but off topic (so I could understand being flagged, etc.), but in all likelihood, these capabilities could say a lot about what happened surrounding the Nord Stream pipeline explosions. I think it's a reasonable assumption that the US has these detectors beyond the borders of the US -- I've seen others claim as much: https://www.thenation.com/article/world/nord-stream-pipeline...

That area of the ocean is probably one of the most heavily surveilled areas in the world. Intelligence agencies absolutely know the ships involved. I still maintain it could have been anyone with about $300k. Work class ROVs capable of planting the explosives at that depth are commonplace in underwater construction and maintenance.

300k ROVs still need a mother ship and pretty sure navies and intelligence agencies know which ships go where and when.

There's an interesting link between K-129 and the current 'boom' around deep sea mining: https://en.wikipedia.org/wiki/Project_Azorian

The cover-story to build the Glomar Explorer to recover K-129 was that Howard Hughes thought that it was economically feasible to mine manganese nodules from the deep sea. A lot of engineering research started that year (1974) that now, 2023, bears fruit in several large companies trying to mine the ocean floor with approvals to start probably happening this year: https://www.nature.com/articles/d41586-023-02290-5

Without the cover-story and Howard Hughes I wonder how many researchers would have ever looked at deep sea mining.

Reminded me of this story: https://en.wikipedia.org/wiki/Toshiba%E2%80%93Kongsberg_scan...

Toshiba wasn't allowed to export a 9-axis (C)NC-machine to the Soviet union, because it could (and would) be used to create ultra-silent submarine props, in the 80s.

Asianometry video about it: https://www.youtube.com/watch?v=uaRyqAVIkwI

> What they're really listening for now are reactor plant noises. Which is why old timey diesel electric submarines still sometimes have the edge over modern subs. No plant noises at all if they are running silent. This leads to some hilarity in joint naval exercises every now and then. e.g. when HNLMS Walrus managed to "sink" among others the USS Theodore Roosevelt before getting away, to great consternation of the…

C'mon though, which US joint exercise partner hasn't 'sunk' a USS craft at one time or another yet? Not to mention the actual real sinkings that are a standard feature of pretty much every RIMPAC nav-mil-cosplay LARP event: * https://gcaptain.com/australian-sub-sinks-us-navy-ship-pract... * https://www.businessinsider.com/us-australia-japan-practice-... * https://news.usni.org/2020/08/31/video-rimpac-2020-exercise-..…

It wasn't just a sunk craft. They sunk a carrier. That's painful. Your wikipedia entry is kind of weird, since it's about Australia and there are no Dutch ships in the list for the last century or so.

Australia has 'sunk' USS carriers in war games also - there are entire books written about how carriers are hard to defend in modern warfare - they're painful to lose but (shhh, don't tell anyone) relativey easy targets in all manner of ways.

The wikipedia entry is about 1400+ ships that were mostly Dutch - from the days of the Dutch East Indies and Spice trades.

It's of interest as that coast was one of the main drivers to develop "GPS 0.1" aka clocks capable of reliable determination of Longitude and one of the (relative to monetary value at the time) largest technology prizes offered.

They stopped stacking up on the West Australian coast once accurate navigation became commonplace but for a while there .. yep, Dutch ships sank themselves.

That's what I'm saying. That's the point of the first paragraph.

That kind of modern journalism is absurd. Originally the rule in journalism was, the first paragraph must contain who, when, what, where, then subsequent paragraphs fill in the details in either chronological or logical order. Now the first paragraph must contain an emotional human-interest style “hook” to rope in the reader, then bury the lede in some random spot in the remainder of the text, in an attempt to keep t…

Yeah. I can usually tell within the first couple of words if the article is worth reading or not. Anything that seems to start with a complete non-sequitur or some variant of “once upon a time” is an immediate back-button bounce for me!

How can you start with a non-sequitur?

I wonder if an active sonar array would be desirable. It would of course be easy to locate the beacons but they would probably be relatively cheap. Also, that much sonar noise would probably be bad for marine life. Would it give us capabilities we currently do not have?

Non-sequitur to the headline?
