a Satellite image of Lützow-Holm Bay obtained by Landsat 8 on 11 November 2017. The contour lines indicate the ocean depth with intervals of 200 m. The location of Lützow-Holm Bay in Antarctica is indicated in the inset. Red arrow is a schematic representation of the Weddell Gyre after Fig. 7 in ref. 25. b Locations of the drilling sites along the ice shelf of Langhovde Glacier (purple dots). The image and surface elevation were acquired by Plèiades on 21 December 2017. The surface elevation contour lines are every 5 m. Black dashed curve indicates the grounding line estimated by the break in slope method20. c Vertical cross-section of Langhovde Glacier along the boreholes. The red crosses are the ice bottom elevation estimated from the surface elevation based on the hydrostatic equilibrium assumption. The surface elevation (black contour) was obtained from elevation model of Plèiades47. The lower boundary of the ice shelf and the ocean bed were drawn by interpolation of borehole measurements and bathymetry map in front of the ice shelf.
