China's ice breaker, the Xuelong, on Wednesday finished crossing the central Arctic area, for the first time in the country's history.

The vessel is currently on a 83-day Arctic rim expedition mission that began on July 20, with 96 crew members and scientists on board.

The scientists did seven "short term ice station works" from August 2 to August 10.

The back-up plan

The crew didn't completely follow their original plan, to save more time for activities in the central Arctic area.

The back-up plan was also carried out due to weather conditions, scientists told China Central Television.

The original plan was not disclosed to reporters.

According to the modified schedule, the team will enter Canada's exclusive economic zone on August 29.
