By Zhang Zhihao | China Daily | Updated:2017-03-07 07:59Amid deputies attending the annual meetings of the top legislature and the top political advisory body, Chinese scientists have broken two world records at the oceans lowest depth – the Mariana Trench, a scythe-shaped clef in the western Pacific Ocean seafloor that plunges nearly 11 kilometers deep.China became the first country to collect the artificial seismic stratigraphy of the Challenger Deep, the deepest section of the trench measured at more than 10 kilometers, the Chinese Academy of Sciences Institute of Geology and Geophysics said on Friday. The stratigraphy is used to study the Earths movement, layers and geologic history.China also set a new world diving record for underwater gliders at 6,329 meters with Hai Yi, a glider designed by the academys Institute of Automation in Shenyang, Liaoning province, the academy said on Sunday. The previous recorder holder was a US glider at 6,000 meters.”These experiments prove that Chinas deep-sea exploration technologies have reached an advanced level,” the academy said in a statement.”Data collected from these experiments are invaluable to the study of continental movement and its transformation,” said Qiu Xuelin, a researcher at the academys South China Sea Institute of Oceanology.Both experiments were carried out by Chinese scientists onboard the academys Explorer-I TS03 scientific surveying ship. They departed Sanya, Hainan province, en route to the Mariana Trench on Jan 15.Upon arrival, they deployed 60 ocean-bottom seismometers to collect data for the stratigraphy on Jan 25. Some seismometers had sunk to 10,027 meters, the academy said, which is enough to submerge Qomolangma (8,850 meters), known as Mount Everest in the West.These instruments can capture sound waves generated by earthquakes or human activities. These waves, combined with the motions of the Earth, can provide details about the geometry of the Earths structure, said Wang Yuan, an engineer at the academys Institute of Geology and Geophysics.The glider is an autonomous underwater vehicle designed to survey marine conditions, such as temperature, salinity and currents, across large bodies of water.Apart from breaking the world record, Hai Yi also completed 12 observation missions across 130 kilometers of water. The data it collected from the abyssal sea is “valuable for oceanologists studying the region”, the academy said.It took Chinese scientists 13 years to design and build the Hai Yi and its variants, it said, adding that there are more than two-dozen types, covering use in shallow sea, deep sea and abyssal sea.PhotoPhotographer transforms female construction workers into elegant ladiesNPC deputies speak up for the grassrootsCliff walkway decorated with 3D imagesBig data: Top word used by Xi during 2013-2016 two sessionsA glimpse of womens makeup in ancient ChinaWomen across the country celebrate their dayLatestYangchuanosaurus to appear on Chinese Dinosaur StampsTibet to spend big on fighting povertyChongqing panda blood donor is a lifesaverChinese scientists plan wearable device that can listen, speakPhotographer transforms female construction workers into elegant ladiesState Council NewsPremier calls for government function to be further transformedPremier Li joins discussion with delegates from GuangxiExclusiveBig data: Top word used by Xi during 2013-2016 two sessionsXis leadership: Empowering women; inspiring equalityDeveloping China, using intellectual capitalEditors picksFirst national park receiving strong legal and financial supportLawmaker calls for end to issue of left-behind childrenTen photos you dont wanna missTen photos from across China: Feb 24 – March 2SpecialCementing countrys rule of lawCircuit courts in ChinaBACK TO THE TOPHOMECHINAWORLDBUSINESSLIFESTYLECULTURETRAVELWATCHTHISSPORTSOPINIONREGIONALFORUMNEWSPAPERChina Daily PDFChina Daily E-paperMOBILECopyright 1995 -var oTime = new Date();
