Deep-sea vents 'no climate haven' (BBC)

By Rebecca Morelle
Science reporter, BBC News, York

Exotic creatures that live at deep-sea vents will not be immune to the effects of climate change, a UK scientist says.

It was thought that life at these fiercely hot volcanic fissures was so independent from the world above that the habitat would prove a safe haven.

But new work finds that some of the animals are reliant on food sources from sea surface level, which could be affected by a change in climate.

The findings are presented at the BA Festival of Science in York.

1. I also wonder about pH sensitivity.

A lot of non-vent organisms are sensitive to pH. I can't think of a reason why vent-dwellers might not also be.
