Dividing the Arctic Ocean into two main basins, Lomonosov Ridge is located in the middle of the Arctic Ocean. In the past, it was surrounded by ice masses from all directions. These ice masses had a greater extent in the former glacial ages. Geoscientific investigations were done in the Expedition PS87 focusing on Lomonosov ridge. To explore Lomonosov Ridge sections that faces the East Siberian Sea, high quality bathymetric data were obtained and post processed. The data revealed erosional evidences presented in the mega scale glacial lineation in two directions on the Eurasian Basin. On the other side of the ridge, which faces the Amerasian basin, mudflow channels were observed on the ridge slope. Furthermore, high quality Parasound profiles were acquired, resulting in 10.370 km profiles. Investiating the Parasound profiles leaded to detect three glacial stages evidences. These evidences are presented in redeposited sedimentary lenses detected in the area strata, where it lays in different sediment depths and different stratigraphic sequence. One stage of these glacial stages characterized by huge volume of redeposited sedimentary lenses, all of the mare located in the same stratigraphic sequence. Strong relationship between this glacial stage and the recent shape of Lomonosov Ridge was found. Finally the detected features analysis gave more understanding to the glacial history of Lomonosov Ridge and the Arctic Ocean.
