Samples of a marine creature collected during Captain Scott's Antarctic trips are yielding data that may prove valuable in projecting climate change.

The expeditions in the early 1900s brought back many finds including samples of life from the sea floor.

Comparing these samples with modern ones, scientists have now shown that the growth of a bryozoan, a tiny animal, has increased in recent years.

They say this means more carbon dioxide is being locked away on the ocean bed.

The tiny bryozoan, Cellarinella nutti, looks like a branching twig that has been stuck into the sea floor.
