Fig. 3: Temperature profiles along Sherard Osborn and Petermann fjords.
From: Ryder Glacier in northwest Greenland is shielded from warm Atlantic water by a bathymetric sill
The temperature profiles, from X to X’ (a; Sherard Osborn Fjord) and Y to Y’ (b; Petermann Fjord) are based on conductivity, temperature and depth (CTD) stations shown in Fig. 1 and numbered at the top of the profiles. Numbers within brackets in red next to the station numbers are the closest distances in kilometres to the 2019 location of the ice tongue margins in respective fjords. The depth profiles are derived from the multibeam bathymetry. Note that the profiles run through the deepest passages across the sills. The sill-crests are indicated by black dashed lines, and are substantially shallower in Sherard Osborn Fjord. Additional temperature profiles constructed from CTD stations in Sherard Osborn Fjord are shown in the Supplementary Fig. 2.
