PhD-project title: Analysis and modeling of the distribution of traces of glacial melt in the Southern Ocean with focus on the southeast Pacific sector
From previous studies, it has been found that Antarctic ice sheet is melting in the southeast Pacific sector. This melting is caused by the the relatively warm Circumpolar Deep Water (CDW) that flows onto the continental shelf in Amundsen Sea and is considered to be one of the major causes for the freshening of the Ross Sea.
Thus, in this study, the observational data is firstly analysed to deepen our understanding of the ice sheet melting in Amundsen Sea. Then, the influence of the glacial melt is analysed with with Finite Element Sea Ice Ocean Model (FESOM).
