Letters from shallow reflection seismic workers diary

Abstract

In the central parts of the Scandinavian glaciations, in Norway, Sweden and Finland, there are a number of Early Weichselian sites with fresh-water sediments, which, by comparison with sites further south, can be correlated with either the Brorup or Odderade interstadials. Few of these sites can with any certainty be correlated with just one of the two. In northern Jutland and at thecoast of south-western Norway there are Early Weichselian marine sediments, some of those in Norway having been interpreted as interstadial.Middle Weichselian fresh-water sediments have only been found in Denmark and southern Sweden, whereas marine sediments occur in northern Jutland and at the coast in Norway, in the same areas as the Early Weichselian marine sediments. Most of the Middle Weichselian sites must be referred to as representing an interstadial complex, as a close correlation with the five interstadials identified in northwest Germany and The Netherlands is not possible.A close correlation has been made between the fluctuations in the deep-sea oxygen-isotope curve and the Weichselian history in Scandinavia, the justification for which is discussed.
