Sea-Level Fluctuation and Coastal Evolution
Sea-Level Fluctuation and Coastal Evolution - This Special Publication is the result of a symposium in honor of W. Armstrong Price held at the first SEPM Midyear Meeting at San Jose, California, on August 12, 1984. The factors controlling relative sea-level change along our shores are varied and, at best, imperfectly understood. Yet, the relative rate of change is what controls shoreline erosion, the arrangement of sedimentary facies of the coastal zone, and the character of deformities within the coastal stratigraphic record. Therefore, these papers address sea-level changes, shoreline responses, and the controls on the three-dimensional geometry of the consequent lithosomes; in short, the architecture of the coastal depositional systems.

Geophysical models 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 closely 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 yrs, 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...
