Summary, in English

Dating the transgression and subsequent regression in marginal basins of the southeastern

Swedish Baltic Sea provides a new perspective of global ice-volume changes and the isostatic

adjustment of the mantle after the retreat of the Scandinavian Ice Sheet from this area. Superimposed

upon a smooth pattern of local sea-level rise, acceleration occurred ca. 7600 calibrated

(cal) yr B.P., evidenced as a nearly synchronous fl ooding in six elevated basins ranging

from 3.0 to 7.2 m above present sea level. We ascribe this rapid local sea-level rise of ~4.5 m to

a sudden increase in ocean mass, most likely caused by the fi nal decay of the Labrador sector

of the Laurentide Ice Sheet. The subsequent monotonic fall of local sea level from ca. 6500 cal

yr B.P. to the present is mainly an expression of the slow isostatic adjustment of the mantle.
