The West Sea Fisheries Research Institute of NIFS, on June 14, held the expert seminar for in-depth analysis of the long-term changes in the marine environment of the West Sea by climate change.

There were expert presentations under the theme of ▲the marine environment and fisheries resources of the West Sea ▲the long-term changes in water temperature of the West Sea and causes, ▲the biogeochemical changes in the environment of the western coastal and offshore waters, etc.

The presenter Dr. Lim, Weol-ae, the director of Fisheries Resources and Environment Research Division, told that the surface water temperature of the West Sea had increased by 1.19℃ on average over the recent 55 years(1968-2022).

The SNU professor Kim, Guebuem told that the nitrate concentration in the surface water of the West Sea had decreased by 0.22µM/yr in coastal areas and increased by 0.09µM/yr in offshore waters.

Nutrients are the key component of primary productivity in oceans, so the concentration ultimately can affect the amount of fisheries resources.
