China Builds World's Largest Silent Research Vessel
The world's largest silent research vessel built by China was officially put into use, which will pave the way for the cultivation of innovative deep-sea talent and ocean science study.Built by Shanghai-based Jiangnan Shipyard (Group) Co., Ltd, the Dong Fang Hong 3 is the first Chinese research vessel and the world' fourth to have obtained a Silent-R certificate, the highest standard for underwater noise control issued by Norwegian international certification body, DNV GL, according to Xie Jun, chief builder of the vessel.The ship is the first one in China and fourth in the world to receive the certification, positioning the vessel at the highest international standard in terms of the underwater radiation noise control in the world.
'Smart Boulders' Measure Seafloor Avalanches
Researchers have deployed high-tech robotic sensors disguised as boulders for the first time to measure the initiation and evolution of the huge, hard-to-measure seafloor avalanches that regularly damage global networks of seafloor telecommunication cables.The so-called "smart boulders" revealed some surprising findings that will help inform where best to lay the seafloor cables that keep the internet running. Published this week in the journal Nature Communications, this research shows that submarine avalanches of rock and sand…
Jensen Hires Jianjun Qi
Jensen Maritime Consultants hired its third naval architect, Jianjun Qi, in the company’s new office in the New Orleans business district, reporting to Jensen General Manager Sergio Fifi. Qi brings to Jensen a decade of naval architecture, marine engineering and shipyard expertise.

Scientists Use Space Technology to Explore Deep Sea
Chinese and American scientists recently have found a new measure to explore deep sea by using space technology. With the help of space satellite, scientists have developed a new method that is similar to the X-rays. By applying this new technology, they have successfully detected Mediterranean Sea eddies 800 meters deep into the water. The success of the project created a precedent for exploring deep sea from the space. This latest breakthrough was announced at the press conference jointly held by US NASA Jet Propulsion Laboratory (JPL), American Meteorological Society, University of Delaware, and Ocean University of China on March 21.
