Korea Ocean Acidification Watch (K-OA Watch) is joint initiative of POSTECH and the Korea Hydrographic and Oceanographic Agency (KHOA) under the OARS Programme.
Centered on the Ieodo Ocean Research Station (northern East China Sea), the project conducts long-term monitoring of ocean acidification in shelf waters.
Weekly sampling targets three core carbonate parameters (pH, TA, DIC), from which additional parameters are derived. This effort will capture long-term trends, seasonal patterns, and short-term variability in acidification, while also quantifying the carbon uptake capacity of shelf seas and identifying its primary drivers.
All quality-controlled data, methods, and code will be openly shared through global repositories, strengthening OARS syntheses and improving regional OA forecasts.
The outcomes will directly inform risk assessment and adaptation strategies for fisheries and coastal communities, contributing to SDG 14.3 by addressing and mitigating OA impacts.
Start Date: 1/1/2026
End Date: 12/31/2030
