Water and EMP

 Water is an excellent absorber of electromagnetic radiation

Extreme electromagnetic incidents caused by an intentional electromagnetic pulse (EMP) attack or a naturally occurring geomagnetic disturbance (GMD), caused by severe space weather, could damage significant portions of the Nation's critical infrastructure, including the electrical grid, communications equipment, water 

EMP AS A WEAPON The non-lethal nature of electromagnetic weapons makes their use far less politically damaging than that of conventional munitions, and therefore broadens the range of military options available. For weapons purposes EMP producing sources other than nuclear detonations have been successfully developed. Several nations, with United States at the forefront, are reported to have developed non-nuclear bombs capable of generating EMPs. Electromagnetic bombs (E-bombs) are specialized, non-nuclear tools designed to destroy information systems.

An EMP shock wave can be produced by a device small enough to fit in a briefcase. High Power Electromagnetic Pulse generation techniques and High Power Microwave technology have matured to the point where practical E-bombs are becoming technically feasible, with new applications in both Strategic and Tactical Information Warfare. Although much of this work is classified, it's believed that current efforts are based on using high-temperature superconductors to create intense magnetic fields. The development of conventional E-bomb devices allows their use in non-nuclear confrontations to defeat an enemy without causing loss of life. Regardless of the method of delivery, experts agree that EMPs can be powerful enough to cripple electronic wiring and circuitry over a geographic area as large as several square miles, posing a real threat to the nation's critical infrastructure.

So what is the effect of these weapons on Water. We are 75% water. What about the water of the oceans? What about the marine life. When are they going to stop? The people of US are proud that they are the most advanced in development of these weapons. Shouldn't they be focusing on the betterment of human life ? 

How long does an EMP effect last?
A study found that exposure to 200–400 pulses of EMP caused the leaking of vessels in the brain, leakage that has been linked to small problems with thinking and memory recollection. These effects could last up to 12 hours after the exposure.

Underwater electromagnetic communications have been investigated since the very early days of radio, and again received considerable attention during the 1970s. Then terrestrial radio typically delivered manual digital communications (Morse code) or full bandwidth analogue voice communications over long range, and research was aimed at delivering these types of service in the underwater environment. In fact, the Extremely Low Frequency (ELF) submarine communications system is believed to be the only successfully deployed subsea electromagnetic application. This system operated at 76Hz for the US system and 82Hz in the Russian system and allowed transmission of a few characters per minute across the globe. It implemented a one way 'bell ring' to call an individual submarine to the surface for higher bandwidth communications using terrestrial radio. Through water, full-bandwidth, long-range, analogue voice communications were found to be impractical and there rapidly developed a 'perceived wisdom' that electromagnetic signals had no applications in the underwater environment. 


In the digital era we have become familiar with the benefits of short-range, high-bandwidth communications systems such as Bluetooth. At the same time, the oil industry and military operations have changing requirements that have created demand for reliable, connectorless short-range data links. An initial investigation revealed that electromagnetic signalling, coupled with digital technology and signal-compression techniques, had many advantages that made it suitable for niche underwater applications. 

Any of them have thought about the impact on aquatic life of these technologies?

S5510 Short Range, Broadband Electromagnetic Communications

The end of 2006 will see the launch of the S5510, a broadband electromagnetic telemetry link aimed at customers who require transfer of large amounts of data (1-10Mbps) over short distances (<1m) under water. This has been designed to support the rapid harvesting of data from underwater sensors by UUVs, with-out the need for a hard docking and at very high Joules-per-bit efficiency. It provides duplex operation with Ethernet bridge functionality. In practice, each deployment has unique requirements. While the S5510 and S1510 platforms provide the bulk of the system functionality, each solution has uniquely to balance parameters such as antenna design, transmit power, duty cycle, data bandwidth, antenna size and local noise sources to achieve an optimised solution for the specific application.

All these technologies affect the water. The internal structure of the water is affected and with the water the structure of the people and animals. When are they going to stop?
