Tsunami Sediment Core.
I am now the proud owner of a core of peat, clay and Storrega Tsunami sediment taken from Maryton near Montrose.

Fraser Milne and Sue Dawson provide the answers to my questions and Fraser has a nice collection of Pollen images taken from the cores now which I hope to plunder soon!
