Response of the Arctic sea ice–ocean system to meltwater perturbations based on a one-dimensional model study
A one-dimensional coupled sea ice–ocean model is used to investigate how the Arctic Ocean stratification and sea ice respond to changes in meltwater. In the control experiments, the model is capable of accurately simulating seasonal changes in the upper-ocean stratification structure compared with o...
