Exotic Canada: Deep, Dark and Hot
A tour of hydrothermal vents
on the ocean floor

Verena Tunnicliffe
The University of Victoria

The hottest water on Earth, over 400°C, gushes into the otherwise barren depths of the cold ocean. One such spectacular site lies in Canadian waters just off Vancouver Island. Hydrothermal vent studies are changing basic ideas in many sciences. They present a new model for the origin of life, explain chemical balances in the oceans, and provide new insights on processes deep within the Earth's crust.

Visiting this last frontier on the planet tests even the best technology. Nevertheless, we can reach these oases of life, kilometres below the ocean surface, using manned and remotely operated submersibles. Once there, we find strange associations between animals and bacteria that form some of the densest biological growths in the ocean.

Hydrothermal vents offer a marvelous habitat where abundant food is available to the venturesome. The challenges, however, include noxious chemical toxins, undependable access to fluids, competition from your neighbours, and a long way to go to the next vent. And just when you have made the perfect home, the volcano under your feet erupts.
