Last night saw the second of the BBC’s spectacular new four-part series, Britain’s Secret Seas, which looks at the amazing marine life around our coast.
Presenter and dive explorer Paul Rose met the Royal Navy divers who train to diffuse bombs in the cold and turbulent waters around Garvey Island off the coast of Scotland.
Disposing bombs underwater has a different set of risks to those on land, and the Navy have to comb through vast expanses of thick sea kelp to locate them, wearing special rebreathers as some bombs are accoustically activated.
Biologist Tooni Mahto headed to the Firth of Forth off the coast of Inverness where dolphins are regularly spotted tracking salmon, and discovered that this breed of dolphin could identify each other through individual names and whistles.
Paul and Tooni visited St Annes Marine Reserve around Scotland’s northern tip, to prove that British marine life is not only more colourful than most people imagine, but could even help in the fight against cancer.
Journalist Frank Pope investigated the problem of by-catch in the North Sea, where each year fisherman net around 900,000 tonnes of by-catch.
And Paul joined Frank to dive the Sound of Mull, off the West Coast of Scotland, to explore some spectacular sunken shipwrecks, including the Dutch cargo ship ‘Breda’, and report on the joys (and dangers) of wreck diving as well as clever new wreck survey technology.
Watch Episode One here on BBC iPlayer, to check out the team’s encounter with the majestic basking shark – Britain’s largest fish – and giant spiney spidercrabs; no doubt a familiar sight to those of us who dive Porth Ysgaden regularly!
