Underwater Civilization


A new study by the University of Bradford demonstrates that magnetic fields may hold the key to comprehending buried civilizations. With the rise of North Sea wind farms, the race is on to collaborate with developers to put together facts about Doggerland ahead of development.

Ben Urmston, a Ph.D. student, will analyze magnetometry data to look for magnetic field anomalies that might point to the presence of archaeological features without the need for excavation, as per the release.

“Small changes in the magnetic field can indicate changes in the landscape, such as peat-forming areas and sediments, or where erosion has occurred, for example, in river channels," he said.

"As the area we are studying used to be above sea level, there's a small chance this analysis could even reveal evidence for hunter-gatherer activity. That would be the pinnacle. We might also discover the presence of middens, which are rubbish dumps that consist of animal bone, mollusk shells, and other biological material, that can tell us a lot about how people lived,” he added.
What is Doggerland?

Doggerland was a piece of land that connected continental Europe to Britain but is now covered by the North Sea. A rise in sea levels circa 6500–6200 BCE caused it to be submerged. The Dogger Littora is the name of the flooded area.

Towards the end of the last ice age, due to global warming, Doggerland was one of the most resource-rich and ecologically dynamic regions during the later Palaeolithic and Mesolithic periods (c.20,000–4,000 BC), was submerged under the water.  READ MORE...

World's Largest Antenna in China



A representative antenna


China has been slowly but steadily working its way to the top. Frequently making headlines with its space-related developments, the country now claims to be operating the world's largest antenna for its submarine operations.

What's special about the antenna is the fact that it was designed to maintain underwater communications over 1,900 miles (3,000 km), enough to reach Guam, the biggest U.S. military base in the western Pacific Ocean, according to the project’s lead engineer Zha Ming and his colleagues from the Wuhan Maritime Communication Research Institute, reports South China Morning Post.

While the gigantic antenna's current location remains unknown, the team said it lies somewhere 620 miles (1,000 km) south of Beijing, 1,242 miles (2,000 km) southeast of Dunhuang in northwest China, and 620 miles (1,000 km) east of Mianyang in the southwestern province of Sichuan.  READ MORE...
