Projection of Nutrient Discharge by Using MRI-AGCM3.1S in Shiretok

A new study projects future nutrient discharge from the Shiretoko Peninsula, a UNESCO World Natural Heritage Site, using the MRI-AGCM3.1S climate model with two bias correction techniques. The research finds that the cumulative distribution function (cdf) correction technique more accurately reproduces nutrient flux compared to the normal distribution method. This insight is crucial as climate change-altered precipitation patterns threaten the ecological balance of Shiretoko, where nutrient circulation between inland and ocean plays a pivotal role in its unique ecosystem. By focusing on precipitation—a key driver of nutrient supply—the study aims to inform conservation efforts and mitigate potential disruptions to this fragile heritage site.
