Short summary
We investigated the long-term changes of the principal tidal component M2 along North Atlantic coasts, from 1846 to 2018. We analysed 18 tide gauges. We found that M2 variations are consistent at all the stations in the North-East Atlantic, whereas some discrepancies appear in the North-West Atlantic. The similarity between the North Atlantic Oscillation and M2 variations in the North-East Atlantic suggests a possible influence of the large-scale atmospheric circulation on the tide.
