On August 10, 2019, "Xiangyanghong 01" research vessel departed from Qingdao to conduct the 10th Arctic expedition mission (hereinafter referred to as "the 10th Arctic"). On August 25, after the expedition completed observation tasks in the open sea of Bering Sea, the FIO undertook the underwater glider observation task, and equipped the "Haiyan" underwater gliders with conductivity temperature depth and dissolved oxygen sensor to conduct the integrated observation of seawater and biochemical factors in Arctic waters.

The project team spent less than an hour completing the deployment of three gliders and making various gliders successfully pass the first 100-meter test section, which saved the time of field operation and demonstrated the good maneuverability of "Haiyan". 

After the three "Haiyan" underwater gliders entered the water, they sailed eastwards to conduct the east-west section observation in the open sea of Bering Sea. During the execution, No. 13 Typhoon Lingling happened to pass the Bering Sea. After communication, the 10th Arctic field team and the "Haiyan" security team quickly decided to change the scheduled cruising routes of the underwater gliders, and put the gliders into the waters where Lingling passed waiting for observations. They realized the whole process observations through path planning and formation collaboration, and fully recorded the effects of cyclones to marine environment. "Haiyan" underwater gliders had presented excellent observation performance, high reliability, flexible operation and timely response. Through 22-day integrated observation, "Haiyan" underwater gliders obtained continuous high-density hydrological and biochemical observation data of the east-west section in the open sea of Bering Sea, and successfully completed the expedition mission. 

After the expedition mission, the 10th Arctic project leader highly praised the team for their successful completion of the mission, "Under the full communication and elaborate design of both sides and under the strong support of the "Haiyan" security team, you realized the integrated observation with underwater gliders in the Arctic waters for the first time and realized the simultaneous observation of hydrological environment and biochemical factors. In the course of the mission, Typhoon Lingling passed the Bering Sea, and you still realized the whole process observations under such severe sea conditions, which also reflected the excellent quality performance of "Haiyan" underwater gliders."

Wei Zexun, the expedition team leader and chief scientist, highly affirmed the excellent performance of "Haiyan" underwater gliders. He said, "During the 10th Arctic expedition mission, "Haiyan" underwater gliders yielded great results in integrated observation in the open sea of Bering Sea, and obtained continuous high-density hydrological and biochemical observation data, and the data about the effects of cyclones to marine environment. "Haiyan" underwater gliders had presented excellent observation performance, high reliability, and flexible operation. Practice has proven that "Haiyan" underwater gliders, as a new type of unmanned observation platform, were applied to polar waters. The successful use of underwater gliders to carry out integrated observation provided a new application demonstration for China to explore the polar waters."

"Haiyan" underwater gliders were jointly produced by the Joint Laboratory for Ocean Observation and Detection (Tianjin University), Qingdao National Laboratory for Marine Science and Technology and SeaHorizon Solutions Group Limited in strict accordance with the quality management system of the national military standard and 6S field management mode. At present, there has been a series of long-range underwater gliders of 2, 10, 15 and 40 million meters. This application also fully verified "Haiyan" technical team's ability in synchronous control of underwater gliders distributed in different waters.
