Submerged Forests around British and Irish Coasts
Summary:
The following article was originally published as an interactive web-page. The map below
shows the principal locations where submerged forests are found around British and Irish
coasts; giving hyperlinks to both popular and specialist reports; some of these will give
further detail and maps together with photographs.
Radiocarbon dates are shown here in square brackets. The dates suggested in the various press
reports should be treated only as an approximate guide to the precise era of submergence and so
are enclosed in quotes. Trees may survive for hundreds of years and it is not always stated whether
radiocarbon dated material has been taken from tree stumps in-situ or from fallen logs. Only dated
wood from the final growth-rings of a stump would be indicative of the true date of submergence.
Older published studies may refer to a 'submerged forest period' during the mid-Holocene,
whereas more recent papers speak of the submerged forests as dating to various eras. This is in part,
an artefact of random sampling of available wood; however it may be seen that samples from the
North Sea coast tend to favour the conventional dating for the submergence of 'Doggerland', while
those around western coats tend to be from a later period.
The list is not intended to be exhaustive of either sites or of links and will need to be updated as
and when new sites or relevant reports emerge. The intention here is merely to give an entry point
for the general reader to the photographic evidence and relevant studies.
