Britain at Low Tide

Palaeobiologist Dr Tori Herridge and her team of experts explore the north coast of Kent around Whitstable. The programme takes a look at the excavation of one of the most significant shipwreck discoveries of recent times, the origins of a strange sandbar, and a forgotten military base in an unusual location which proved pivotal in deciding the outcome of the First World War. Plus, a look at how rising sea levels and coastal erosion mean that a great deal of archaeology may be lost before it can be documented.

Palaeobiologist Tori Herridge and her team investigate the coastline of Scotland, uncovering archaeological finds that have been left behind by the tide in the inner reaches of the Firth of Forth.

Plus, why a 16th-century entrepreneur decided to tunnel under the sea and how a 19th-century pier proved vital to the continuing success of cattle farmers across central Scotland.
