Estimation of freshwater discharge from the Kamchatka Peninsula to its surrounding oceans
Study Region: Kamchatka Peninsula, Russian Federation. Study Focus: The strength of an overturning process of North Pacific sea water originating in the Sea of Okhotsk is determined by the sea water salinity in the area. Recent observations show that the overturning process is important to the entir...

Our result shows a significant negative correlation (r2 = 0.36, p < 0.01) between the interannual variation of sea water salinity in the overturning process area, and the variation of annual freshwater discharge from the western KP, therefore successfully verifies that freshwater discharge from the western KP is a critical factor that affects the strength of the overturning process.
