摘要

The paper reports preliminary findings of ground-penetrating radar investigations into the internal structure of Holocene coastal dunes and the association of subsurface sediment properties, determined from borehole samples, to reflected images. The area of investigation is on the north coast of Northern Ireland and the coastal dunes are confined systems of mid-to-late Holocene age (less than 6000 years BP). The major influence on subsurface reflections is moisture and organic content; compaction of sediment is another important factor, albeit difficult to quantify. Dipping reflectors and deflated sections are attributed to former dune ridges. The study highlights the need for other investigative techniques to be used in conjunction with ground-penetrating radar for a more coherent picture of dune internal structure.
