Detailed mapping of the seabed is increasingly important for the laying of vital communications cables that connect different regions of the world and the installation of ocean based energy infrastructure. Knowing the contour and makeup of the seabed strata is critical to safe and reliable cabling, ...
Earle’s company Deep Ocean Exploration and Research (DOER Marine), founded in 1992 and based in a hangar at Naval Air Station Alameda, has already built several submersibles and remotely operated vehicles, and helped launch Google Earth’s oceanic underwater map module. Taylor now has a team ...
The system has two ocean-bottom seismometers and two tsunami meter pressure gauges. At the end of the cable, the deep-sea observatory is equipped with a current meter, CTD sensor, TV camera, ...
The first NOC Autosub vehicle missions took place in 1997. Since then, NOC Autosub AUVs have been used extensively for ocean research in remote and hostile environments where endurance, reliability and the ability to operate independently with little or no vessel support are essen...
and MrEllis, Chief Engineer of the Burmah Oil Company. It was essential in war time to use terminology that conveyed nothing to the enemy. Furthermore, the use of the words pipe and pipeline was forbidden, all concerned with the project being encouraged to think of cables rather than pipes...
They are also capable of operating autonomously for extended periods, often weeks or even months, without the need for human intervention, so they become valuable tools for long-term ocean monitoring and research missions, as well as for collecting data in remote or inaccessible areas of the ...
In Section 5, underwater inspection technologies are reviewed for archaeology, underwater security, cables, and pipelines inspections. Finally, some conclusions are drawn, and the development trend of underwater sensing technologies is predicted. 2. Geological Survey Although ocean observation has been ...
Since 1985, underwater optical fiber cable has played a significant role in communications. It has numerous advantages, such as high reliability, large capacity, as well as an excellent communication quality. However, these cables are also vulnerable to potential hazards, such as turbulent currents,...
[From the time of Caesar until the the 13th Century we find little or no mention of the use of anchor chains. Between 1200 and 1700 A.D. we read that iron cables are sometimes used. The statutes of Genoa of 1444 make brief mention of “iron anchor chains.” An engraving of 1512 sho...
A roadmap of future RF mount lenses DSLR-sized glass means DSLR-sized ports. Therefor, Sea & Sea, like many other housing manufacturers, decided to keep their MDX DSLR ports compatible with theEOS R housing. This is great news if you are already invested in Canon or Sea & Sea. You ca...
