Multiple occupations of transatlantic hydrographic sections at 58°N and 46°N between 1991 and 1999 reveal a significant redistribution of subarctic and subtropical water masses north of 40°N, following a sharp drop from extremely high to extremely low values of the North Atlantic Oscillation index in 1996 and its slow recovery towards the end of the decade. This led to significant shifts of the Subarctic Front, indicating a contraction and re-expansion of the Subpolar Gyre.
