Tha an Cuan a Tuath ainmeil airson stoirmean mòra, raointean mara àibheiseach an tràghaidh agus costaichean sgorrach ach tha e cuideachd na àite cudromach airson eunlaith a tha ag imrich. Tha pìosan dhen Chuan a Tuath neo-aithnichte, le saoghal eile fon uisge a tha doirbh faighinn thuige. Thairis air an dà phrògram seo tha sinn a' faicinn nithean nach fhaca mòran: Cearbain-grèine a tha suas ri seachd meatairean de dh' fhaid a' briseadh uachdar na fairge faisg air creagan geal Dobhair. Anns na fiòrdan Nirribheach tha an Cearban Graonlannach a' liùgadh tron mhuir domhainn, fuar. Air taobh na Gearmailt, tha sinn a' faicinn peileag, a' mhuc-mhara as lugha a th' ann còmhla ri na laoigh òg aice. Agus mu-dheireadh, aon de na h-àrainneachdan as torraiche air an t-saoghal, an Cuan Wadden. Anns an t-earrach agus an fhoghar, tha eunlaith a tha ag imrich a' cleasachd san adhar, agus tha a h-uile nì a tha seo a' tachairt air a' Chuan mhòr a tuath.

The North Sea, renowned for storm floods, vast tidal landscapes and rugged coasts, is also one of the most important intersections for bird migration. It is extremely varied and surprisingly unknown, with its diverse underwater world often difficult to access.

This two-part documentary shows the rarely filmed and spectacular basking sharks, measuring up to seven meters long, surface off the white cliffs of Dover. In the Norwegian fjords, the even rarer Greenland Shark that skulks its way through the ice-cold deep sea. The German North Sea offers the smallest of all the whales, the porpoise, with its young.

And lastly, the Wadden Sea, among one of the most productive environments on earth. In spring and autumn, flocks of migratory birds stage breathtaking air-shows, like we've never seen before, all over the vast North Sea. Show less
