Exploring the deep

Finding out about our oceans before we boil them to death:

Scientists have begun the first detailed exploration of a vast underwater valley the size of the Grand Canyon - just off the coast of Portugal - and it has yielded a series of surprises.

Using Britain's ISIS robot submarine - a van-sized bundle of high-technology - researchers are for the first time able to view previously hidden features up to 5km (three miles) deep in the Nazare Canyon.

The canyon extends out into the eastern Atlantic from the seaside town of Nazare, north of Lisbon - long plotted on maps but until now never properly studied.


For Professor Paul Tyler, a marine biologist, the expedition is a chance to establish a baseline of data about this undersea world - so the effects of climate change can be assessed.
"We've seen signs of change at the surface and in other parts of the deep ocean at 5,000m; so we need to see what's changing here.
"There is nowhere on the planet that is immune from climate change."

As I have posted before, we're seeing a lot of deep sea creatures recently.
