low, it would seem that there are more factors involved in sea-level changes 

 than have been considered heretofore. The reality of a 120- to 140- fm sea- 

 level now during the late Wisconsin should not, at this time, be rejected out 

 of hand. (Author) .

Geophysical model propose that a former path of ice retreat can be 

 divided into sea-level zones based on the thickness of ice over the region. 

 The predicted position of these zones fits remarkably close to the observed 

 positions . 



Fifteen different, detailed curves of relative sea-level have been 

 obtained in the Atlantic Canadian area and three composite curves derived from 

 these data are presented here. These data exhibit highest resolution in the 

 last 4,000 years, but one area provides a complete record since deglaciation 

 and two other sites provide data from 7.0 ka to the present. A clear trend is 

 apparent in these data: relative sea- level rise is greater seaward of the 

 former ice margin with no former shorelines above present sea- level. As one 

 moves across the former ice margin toward the former ice center, there is 

 evidence of early sea-level fall but no raised marine features. Closer to the 

 ice center, old raised shorelines appear but present sea-level is rising. 

 Close to the former ice center, relative sea-level is still falling with no 

 evidence of any past relative sea-level rise. 



Atlantic Canada demonstrates the complex inter- relationships which can 

 develop over short distances between relative sea-level and resulting 

 sedimentation. For interpretation of relative sea-level and sedimentation 

 history in glacial regions, it is critical to locate the position of maximum 

 glacial advance. Finding this position helps delineate the boundary between 

 original areas of erosion and deposition and determines sources and quantities 

 of sediment as sea-level modifies a coastline. It also determines whether 

 glacial deposition will be concentrated in terrestrial, continental shelf or 

 continental slope and rise environments. (Authors).

Previous studies of sea- level and tidal amplification in the Bay of 

 Fundy suggested a linear increase of tidal amplitude as relative sea- level 

 rose. New data presented here are used in a numerical tidal model in an 

 effort to reproduce paleotidal regimes over the last 7,000 years. Five new 

 sea- level curves covering the last 4,000 years and some previously published 

 data extending the record back to 7,000 years before present (B.P.) are used 

 as the data base. These data, when used together with the tidal model, 

 indicate that tidal amplitudes increased much more rapidly between 7,000 and
