Abstract

The solar radiation has been increasing globally since the 1990s (global brightening). This is the first paper that examined the effect of increasing solar radiation on primary production and hypoxic water in coastal area. We performed a numerical experiment using 3D hydrodynamics and ecosystem model in Ise Bay, where the annual solar radiation had increased by 13.3% from 1980 to 2010. The model results reveal that both the annual mean primary production and the hypoxic water area decreased by reducing solar radiation (10%) from the 2010 level. Our results illustrate how elevating solar radiation influences the coastal environment, particularly hypoxic water area, by using the numerical experiment.
