Stratification Follows Discharge

The claim

Coastal stratification in the Arctic is set by the ratio of river discharge to wind mixing, so a windy year can erase a large freshwater input.

01Mechanism

Freshwater stratifies while wind mixes; the ratio determines whether the buoyant layer persists into summer.

02Prediction

Stratification should track the ratio.

03Refutation

Stratification tracking discharge alone would remove mixing.
