Underwater noise and waves can modify the behavior of certain underwater species, such as migratory behavior, disrupting communication or reproduction. Available information is that underwater noise generated by submarine cable engineering operations has limited acoustic footprint and limited duration. [128]

The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. [1] The system runs from the eastern coast of North America to Japan. [2] Its Europe–Asia segment was the fourth longest cable in the world in 2008. [3]
The only aim of blue crime is monetary profit. One form of criminal activity against submarine cables is cable theft. An example is the cable between Singapore and Indonesia, which was partly robbed in 2013: 31,7 km and 418 tons of cables were removed. [33] Another scenario is a criminal group threatening to harm cables if no ransom is received.
SEA-ME-WE3 was based on the success of the earlier shorter cable SEA-ME-WE2. At the time of commissioning, 18 October 1994, SEA-ME-WE2 was the world's longest optical fibre submarine cable system at 18,751 km. The cable has two single mode fibre pairs with a combined capacity of 1.12 Gbit/s, (2*560 Mbit/s), 151 repeaters and 9 branches. [39]
Maximum depth 1000m. Total cost 380 million EUR. It is the longest submarine/underground AC cable interconnection in the world.

When the first transatlantic telegraph cable was laid in 1858 by Cyrus West Field, it operated for only three weeks; a subsequent attempt in 1866 was more successful. [citation needed] On July 13, 1866 the cable laying ship Great Eastern sailed out of Valentia Island, Ireland and on July 27 landed at Heart's Content in Newfoundland, completing the first lasting connection across the Atlantic.
