英文摘要 | Vertical land motion (VLM) from past and ongoing glacial changes can amplify or mitigate ongoing relative sea level change. We present a high resolution VLM‐model for the wider Arctic, that includes both present‐day ice loading (PDIL) and glacial isostatic adjustment (GIA). The study shows that the non‐linear elastic uplift from PDIL is significant (0.5‐1 mm y‐1) in most of the wider Arctic and exceeds GIA at 15 of 54 Arctic GNSS‐sites, including sites in non‐glaciated areas of the North Sea region and the east coast of North America. Thereby the sea level change from PDIL (1.85 mm y‐1) is significantly mitigated from VLM caused by PDIL. The combined VLM‐model was consistent with measured VLM at 85% of the GNSS‐sites (R=0.77) and outperformed a GIA‐only model (R=0.64). Deviations from GNSS‐measured VLM can be attributed to local circumstances causing VLM. |
