Tang.ɢwan – ḥačxʷiqak – Tsig̱is MPA: A Deepsea Oasis
Thousands of metres beneath the swells of the open ocean west of Vancouver Island is the Tang.ɢwan – ḥačxʷiqak – Tsig̱is (ThT) Marine Protected Area (MPA). This mysterious Deepsea Oasis is teeming with life.
The waters of Tang.ɢwan – ḥačxʷiqak – Tsig̱is have enriched the lives of the Haida, Nuu-chah-nulth, Pacheedaht, Quatsino Peoples for millenia. Pronounced Tung – Gwun, huch/khwi/kuk, tsee-geese, the marine protected area name consists of:
– a Haida word meaning deep ocean (Tang.ɢwan),
– a Nuu-chah-nulth and Pacheedaht word meaning deepest part of the ocean (ḥačxwiqak),
– and a Quatsino word referring to a monster of the deep (Tsig̱is).
Whales and seabirds on the ocean surface have long signaled a rich ecosystem below. First Nations are working with Fisheries and Oceans Canada to protect and co-manage their fishing territory.
In these dark waters, seamounts rise 3000 metres above the seafloor, extending higher than Whistler Mountain. These underwater volcanoes are biodiversity hotspots offering a buffet for marine wildlife. Like the Galápagos Islands to the south, each of the nearly 50 identified seamounts is unique, providing critical habitat.
Hydrothermal vents, which are like deep sea hot springs, release superheated water and minerals from under the Earth’s crust. These vents are home to 10 species recorded nowhere else in the world.
Did you know? The such as a sea spider and a microbe that can live here in hot waters reaching as hot as 121°C. Some marine life, like tube worms, have adapted to create energy without sunlight.
Tang.ɢwan – ḥačxʷiqak – Tsig̱is encompasses all of Canada’s hydrothermal vents and 75% of its known seamounts.
