Landfast ice plays an important role in atmosphere‒ocean interactions and ecosystems the near coast area of Antarctica. Understanding characteristics variations landfast is crucial to study climates field activities Antarctic. In this study, a high-resolution thermodynamic snow-ice (HIGHTSI) model was applied simulate seasonal changes along Mawson Coast, East Antarctica, through ERA-Interim reanalysis data. Four ocean heat-flux (Fw) values (10, 15, 20 25 W m−2) were used sensitivity experiments. The results showed that it reasonable using HIGHTSI model, simulation thickness matched best well with measurements when Fw m−2. Then, 2-D distributions from 2006 2018 modeled by data 0.125° × cell grid as external forcing. fast thicker thinner open water, usually reaches its maximal October, varying 1.2 2.0 m area.
