Telecom Cables Wanted For Climate Research
schliz writes "Oceanographers have called for telecommunications companies to use their active and retired submarine fibre to collect climate data. Sydney University's John You says voltmeters could simply be attached to cable landing stations to measure ocean currents via the electromagnetic current that they generate. More information about salinity and seismology could be collected by attaching sensors to repeater boxes that are typically installed every 100km of cable to amplify signals. Because fibre optic cables could remain under the sea for decades, they could be a consistent, continual source of data for researchers."
"Voltmeters would cost up to $3,000 to set up, he said, and because fibre optic cables could remain under the sea for decades, they could be a consistent, continual source of data for researchers."
Somebody's unclear on the concept, and I don't think it's me.
What if we found out something we really don't want to know?

With a shunt perhaps. Another fancy way of saying that is an ammeter.

The summary differs with a significance from the article to a somewhat unusual degree... No, it's not really workable with how the systems are currently set up. Yes, there is a possibility for infrastructure (at significant cost) to be colocated on these lines for data-gathering purposes.

They do know they plow the cables into the sea bed floor. Something like 2m down. How is buried in the dirt/mud/sand going to read ocean currents, temp, salinity etc?
Apparently climate change is caused by foreigners and migrants. Dick Smith can see them from his helicopter and he told us. So we're just gunna close our borders and leave you guys to take care it ok? Oh, we'll set up a "citizens' assembly" where we'll talk about climate change like we believe it's a real problem, but ultimately we know it's your problem, not ours.
How we know is more important than what we know.
*to not be guilty of outright plagiarism, I got this from Tim Hunkin the highly-understated host of the secret life of machines.
I first read it as "...Sydney University's John You says volunteers could simply be attached to cable landing stations to measure ocean currents via the electromagnetic current that they generate..."
Mine's more interesting.

Those cables are for sending that pr0n to me, high speed from the USA, land of the free - not for proving anything scientific; besides I can lookup 'climate change' on Google or Bing or even Slashdot and hey presto - all the pros and cons are already there including lots of data (which paradoxically I could download but that would use more electricity which would probably come from a coal fired or gas fired electricity station nearby)?
Who do these scientists think they are, telling me that their scientific experiments and data collecting might tell the truth with careful analysis; I believe what I read on the Internet!
Accoring to TFS, fibre optic cables can lie around for years collecting data, which is measured by voltmeters sensing magnetically-induced currents.
Since when can you induce measurable currents in glass and plastic this way?
I would find TFS far more believable if this was being done to copper wires.
Do daemons dream of electric sleep()?
Kind of like that Portland "masseuse" did before he blasted his man-chowder all over her leg.
"You was part of an international group of oceanographers..."
My first reaction was to twitch, then I realized what was going on.

This museum has a fascinating collection of things to do with undersea communication, focusing on the early telegraph lines. A number of cables come ashore at the museum site, and they've hooked some of them [*] up to an amplifier and loudspeaker. The currents induced in the cable form sounds that vary from noise to eerie wailings.

If these voltmeters had been up and running in the gulf before the spill, could they have somehow informed us about the size or the spread of the spill?
