A four-dimensional time–space trend model to be applied in the reconstruction of former sea levels and ice-front recession

Abstract

Dating ice-front recession by means of late-glacial shoreline diagrams is a classical method in Quaternary geology. In Nonvegian fjord areas this was the most common method of dating ice-front recession chronology before the introduction of the radiocarbon dating method. The shoreline diagram has been used to correlate characteristic events in sea level and ice-front recession chronology on a relative time scale. The major inconveniences of this method are the relative time scale, a coarse time resolution and projection problems in the construction of the diagram.
