EXPLORER 2 AND STRIVER - SCIENCE AND TECHNOLOGY

News: China takes lead in mapping the deep

 

What's in the news?

       It is usually the sightings of the Chinese military's latest warships, and the occasional submarine, that attract the most attention in the crystal clear waters off this tropical island in the South China Sea.

 

Explorer 2:

       Explorer 2 is a green-and-white vessel that might pass for an unremarkable trawler.

       Departing from Sanya's Institute of Deep Sea Science and Engineering (IDSSE), the vessel has made increasingly frequent forays into some of the least explored parts of the world's oceans, carrying with it one of the most advanced deep-sea submersibles, as well as China's ambitions to dominate the still evolving, yet highly competitive, field of deep sea exploration.

 

Fendouzhe or Striver:

       Striver is a manned submersible plunged to a then record depth of more than 10,000 meters in 2020.

       In December 2021, the Striver explored the Mariana Trench, the world's deepest.

       At the Kermadec Trench in the Pacific Ocean, the submersible created several firsts, observing for the first time anemones at a depth of 8,880 meters and fish feeding on shark remains at 9,900 meters.

 

IDSSE:

       The scientific mission of the IDSSE, which is jointly run by Beijing's elite Chinese Academy of Sciences (CAS), the country's premier scientific in- stitution, and the Hainan provincial government, is in line with Mr. Xi's current push to establish China as a science and technology power.

       The institute has been given 30 billion Yuan ($4.3 bil- lion) in grants for the 400 projects it is currently pursuing. Its mission is to create "a China-led global deep sea scientific research programme with joint participation by numerous major international deep-sea research teams".

       The Kermadec project was run along with New Zealand, while IDSSE is China's designated member of the BRICS "Marine and Polar Science" working group.

 

Significance:

       IDSSE say their main mission is understanding what lies at the depths of little understood ocean trenches.

       From the ecological perspective, it will be helpful to monitor long term changes to mining areas, how long it takes to recover, and so on.

       Only the U.S., France and Russia have similar capabilities, the China has developed the deep sea studies.
