Sea of Glass
In 1987 a remarkable discovery was made just off the BC coast. 200 metres below the surface, in the inky blackness of the deep sea, Canadian scientists found an underwater oasis exploding with life: gigantic reefs built by fragile glass sponges. The reefs cover hundreds of square kilometers of sea floor and in some places reach the height of an eight story building. British Columbia’s Sea of Glass is a Canadian national treasure.
