Underwater acoustic detection technology wins gold medal at students' innovation competition

A team of the National University of Defense Technology won a gold medal at the newly-concluded China International College Students' Innovation Competition for their underwater acoustic signal processing system.

The system consists of a visualization software and a computing platform, and is mainly used for detecting, identifying, locating, and tracking underwater targets. It enhances the maritime security via artificial intelligence technologies.

The system was developed by a team of the College of Meteorology and Oceanography, called "the smart ear of the sea."

"The team have applied knowledge learned in class and skills gathered in experiments into the underwater acoustic detection and have received a good result. In future, we will keep innovating and make our contribution to the building of China into a strong maritime country," said Wang Qiushi, a team member.

The competition wrapped up in Shanghai on Oct 15. This year's competition attracted over 20 million college students from 153 countries and regions.

A massive avalanche occurred in northwest China's Xinjiang Uygur Autonomous Region at 18:09 on Thursday, engulfing the entire valley below in seconds.

The dramatic moment was captured by surveillance cameras in the Oytagh Glacier Park scenic area in Akto County. The video shows an enormous mass of snow cascading down from the summit of Chakragil in the Kunlun Mountains. As the avalanche unfolded, the snow accumulated rapidly, forming a towering "snow wall" tens of meters high and covering the entire valley in less than a minute.

Fortunately, the avalanche occurred in an uninhabited high-altitude area, so no injuries or casualties were reported.

The Chakragil, which is more than 6,000 meters above sea level, is constantly covered with snow. The region had recently experienced heavy snowfall, resulting in a build-up of snow thick enough to trigger the avalanche.
