Britain at Low Tide - Season 3

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. Tori also uncovers the story behind a long-forgotten harbour that is regarded as the birthplace of the Scottish whisky industry. 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.

Tori Herridge and her team of archaeologists explore the coastline on the north-west border between England and Scotland, looking into the intertidal archaeology to be discovered when the waters pull back from the magnificent Solway Firth. They uncover the story of a mining disaster that took place four miles out to sea and reveal why one of the Victorian era's greatest feats of engineering failed to stand the test of time. Plus, the discovery of a huge timber oval-shaped swimming pool off the edge of the coast.
