Evaluation of nutrient flux from Shiretoko into the ocean using MRI-GCM

Researchers found that rainfall intensity, particularly its standard deviation, significantly controls nutrient flux from Shiretoko's inland areas to the coast. This discovery highlights a key factor influencing coastal ecological systems. To estimate future nutrient supply, the study used bias-corrected data from the Meteorological Research Institute Global Climate Model (MRI-GCM), which aligns well with observed rainfall data. A synthetic generation technique produced hourly rainfall data, crucial for assessing nutrient dynamics in Shiretoko's river basins. The findings suggest that nonlinearity in rainfall intensity strengthens its impact on nutrient flux, providing critical insights for understanding coastal nutrient cycles.
