Much to my surprise, I learnt today that, after decades of trying, finally submarine seismometers are going to be deployed in larger numbers.
Here is the article: Deploying seismometers where they’re needed most: Underwater Geophysicists hope to use some combination of three approaches to remedy the dearth of seismic data from the oceans.
Quotes from the above article (emphasis added):
- “Whereas about 1900 seismometers have collected data in the ocean over the past 20 years, the nongovernmental International Seismological Centre lists about 11 500 active sensors on land globally” [Shocking!]
- “The engineering of a modern-day ocean-bottom seismometer (OBS) ... “They’re basically like robots that don’t talk to home for a year, ...” [What? For a year?]
- “... high-quality OBS costs about $100 000 to build, whereas a land-based seismometer is about one-fifth of that price”
- “Over the past several years, …. scientists have shown that it’s feasible to attach seismic sensors to fiber-optic cable with a negligible effect on the cable’s reliability. Seismometers known as SMART sensors would collect seismic data using a small fraction of the cable’s power and bandwidth”
- “ It’s a floating network of seismometers known as MERMAID, or Mobile Earthquake Recording in Marine Areas by Independent Divers. The instruments are mobile, are about a third as expensive as OBSs, and can be deployed in remote locations without the need for a return trip to collect data. They drift and float in the water column listening for earthquakes. Each time they sense one, they record the data, move to the surface, and transmit the information to a satellite. ... This map shows the location in the Pacific of the 25 currently deployed MERMAIDs.” [Only 25 deployed?]
Perhaps, these seismometers will shed more light on e.g. sea level rise in some coastal areas of our globe!
This tidbit confirms once more that Global Warming (a.k.a. Climate Change) is the greatest hoax perpetrated on humanity in generations! We still know so little about the sun and the oceans that this constant indoctrination with the climate religion is unbearable!
