China's 13th scientific expedition to the Arctic Ocean has reached the North Pole region and begun research work, according to the Ministry of Natural Resources.

The research will help fill the gap in China's database about the North Pole region, enable scientists to further understand the process of changes in sea ice and ocean currents 

Since arriving in the region onboard the Xuelong 2 on Tuesday, researchers have carried out comprehensive surveys on the atmosphere, hydrology, biology and sea ice, the ministry said in a news release on Thursday. The vessel is the country's first domestically built polar icebreaker.

The research will help fill the gap in the country's database about the North Pole region, enable scientists to further understand the process of changes in sea ice and ocean currents and expand knowledge about the rapid environmental changes in the Arctic Ocean and its ecological response. It will also provide data support for effectively coping with the impact of global climate change on China, the ministry noted.

The expedition team set sail from Shanghai on July 12. They are expected to travel nearly 15,500 nautical miles (28,700 kilometers) before returning to Shanghai in late September.

The project will focus on the central section of the Pacific Arctic Region and the Gakkel Ridge.

Researchers are scheduled to perform a host of tasks such as long-term observation of key environmental elements, geological and geophysical surveys of Gakkel Ridge, atmospheric, sea ice, marine and subsurface environmental surveys, as well as investigations of biomes, resources and pollutants.
