3. Low salinity water found in waters of Ieodo Island
Possibility of inflow into the Jeju coastal regions

It has been confirmed that low saline water has entered into the waters of Ieodo (이어도) Island off the coast of Jeju.

According to the National Institute of Fisheries Science and the Jeju Maritime Research Institute, fresh water with a salt concentration of 26 psu, which is the typical standard for low saline water, was first analyzed at 6 a.m. on the 6th. Since then, the salt concentration has decreased to 25 psu.

The Jeju Maritime Research Institute explained that fresh water from China was found to have flowed into Ieodo (이어도) with the southwest wind, and added that there may be a possibility that those waters will also flow into the coast of Jeju.

The maritime research institute will launch a full-scale marine survey early next week to determine the size and the approximate direction of the low salinity water.

이어도 해상 '저염분수' 관측…제주연안 유입 '유동적'

제주 이어도 해상에 저염분수가 유입된 것으로 확인됐습니다.

국립수산과학원과 제주해양수산연구원에 따르면
6일 오전 6시 기준 저염분수 기준인 염분농도 26 psu의
담수가 유입됐고 지금은 25psu까지 낮아진 것으로
관측됐습니다.

해양수산연구원은
중국발 담수가 남서풍을 타고
이어도까지 유입된 것으로 파악됐다며
제주 연안까지 밀려올 가능성은
유동적이라고 설명했습니다.

수산연구원은
저염분수 규모와 이동경로를 파악하기 위해
다음 주 초 본격적인 해상 예찰에 나설 예정입니다.
