Korea-US joint exploration of the Yellow Sea … Identification of the cause of sea fog

The Korea Institute of Ocean Science and Technology (KIOST, Director Kang Do-hyung) will conduct a joint Korea-U.S. exploration to identify the cause and disappearance of sea fog (sea fog) in the Yellow Sea for 20 days from June 20 to July 9.

Sea fog is one of the causes of marine disasters and disasters due to fog occurring in the sea and coastal areas. Not only does it threaten safe operation of ships, but it also interferes with port operations and bridge traffic. It is known that detection and prediction are much more difficult than land fog because it is intricately intertwined with the changing marine environment and atmospheric elements from moment to moment.

The Yellow Sea is the area where sea fog occurs most often in the world. Ship safety accidents due to sea fog or island residents are often blocked.

A joint South Korea-U.S. research team scientifically identifies such a maritime issue. In the entire process of the occurrence and extinction of sea fog, the underwater, sea, and atmospheric conditions are closely observed in three dimensions, and the correlation between fog and turbulence is also revealed.

The KIOST Maritime Research Ship Onnuri will be equipped with CTD (equipment to measure salt, water temperature, and depth) and ADCP (equipment to observe the speed and direction of ocean current by water layer) that precisely observe marine and atmospheric conditions.

Information is also collected from the Chollian Satellite 2B (GOCI-II) and the Comprehensive Ocean Science Base (Ieodo, Gageocho, Socheongcho), and surveys using the Meteorological Administration's meteorological observation line No. 1 and the meteorological aircraft Nara are also conducted at the same time.

In this joint Korea-U.S. exploration, we will clarify the entire process from the occurrence of sea fog to its extinction, and improve the accuracy of the technology to predict the occurrence of sea fog to contribute to the prevention of marine accidents and the creation of a safe sea environment, said Kang Do-hyung, president of the institute."
