     "abstract": "The results of a land-based multi-disciplinary study of the past ice surface elevation in the Grove Mountains \nof interior East Antarctica support a dynamic evolution of the East Antarctic Ice Sheet (EAIS). Moraine boulders of \nsedimentary rocks and spore pollen assemblage imply a significant shrinkage of the EAIS, with its margin retreating \nsouth of the Grove Mountains (~450 km south of recent coast line) before the middle Pliocene. The exposure ages \nindicate that the ice sheet subsequently re-advanced, with the ice surface rising locally at least 450 m higher than today. \nIt then went back down constantly from before 2.3 Ma to 1.6 Ma. The glacial topography and existence of soil show \nthat the ice surface fluctuation continued since the early Quaternary, but with highest levels never exceeding ~100 m \nhigher than today.",
