| T6-1 | Arctic, Greenland - Avannaata Municipality, terrestrial | None | Piston corer | 69.12200 | -50.62500 | 7.0 | 3.0 | Assigned 'Lake Name' based on Figure 5: Lake name + the number core they kept from the lake. Water depth from Figure 5 schematic (when shown). Core length from Figure 5 schematic (when shown). Lat/Long not given in paper, using Gowan (2023) which has accurate lat long for the lakes. ; Depths are estimated as described in 'Cores' and 'Samples' tabs. ; Depths are estimated as described in 'Cores' and 'Samples' tabs. ; Top/bottom depth reported in paper in m below water surface. I've converted that to m in sediment section by subtracting the water depth. |

|---|---|---|---|---|
| T6 | Lake lies on a wide bedrock shoulder below the ridge that defines the southern margin on Jakobshavn Isfjord. Above marine limit | False | None |
