During the austral summer season in 2019, an international collaborative project entitled “Schirmacher Oasis Nippon (Japan) India Coring (SONIC) Expedition” between Japan and India carried out intensive fieldwork in the Schirmacher Oasis based out from Maitri, the Indian research station. A total of 20 sedimentary cores were retrieved from nine lakes in the Schirmacher Oasis by using a newly developed percussion piston corer. Among them, fifteen cores were transported to Japan by airplane, and several non-destructive analyses and visual descriptions were conducted at the Marine Core Research Institute, Kochi University. In this report, we compile these core data to present basic information for further research on ice-sheet variability.
