Summary: | Snow and first-year sea ice ridge thickness, draft and morphology were measured using a 2-inch ice drilling auger (Kovacs Enterprises) during walking surveys on first-year ice ridge during the MOSAiC expedition. Drilling was performed during January and February 2020 across three drilling transects located 20 m from each other. The investigated "Fort Ridge" was formed from late September to early October 2019 between second- and first-year ice. It was approximately 90–100 m long and 20–30 m wide. The ridge was located on drifting sea ice in the Arctic Ocean within the Central Observatory of MOSAiC. The table contains the event label (1), event ID (2), time (3), and global coordinates (4,5) of each drilling measurement. Each separate drilling hole has its number indicating cross-section and number within cross-section (6), and local coordinate X (7) in [m] and transect name (8). Global coordinates are given for the local coordinates of X = 22 m at the transect 1. For each drill hole, the depth relative to the ... |
