Abstract Changing sea ice conditions and thawing permafrost in the Arctic could lead to dramatic changes in coastal erosion dynamics. To address this issue, the Arctic Coastal Dynamics (ACD) project brought together experts from all circum-Arctic countries around a common project: the ACD classification of Arctic coasts. This paper uses 545 segments from the beta version of the ACD classification to investigate statistical relations between coastal erosion rates on Arctic coasts and ground ice content. Ground ice content and retreat rates are only weakly correlated statistically (r = 0.48, relationship statistically significant at a = 0.01), but the multifactor nature of coastal erosion in the Arctic shows us that ground ice is a major factor affecting erosion processes. The current study integrates several geographical settings and time scales and is therefore integrative enough to be used as a benchmark for future empirically based models.
