Antarctica, Wild Geese and Ash Plumes

Comments (0)

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). Richard Hollingham finds out that the freezing seas around Antarctica are not barren and lifeless.

The Census of Marine Life is building up a picture of the richness and diversity of life in the world's oceans and has so far found thousands of species on shelves around the frozen continent. Incredibly, scientists are still finding new species.

At this rate, researchers will soon have documented 17,000 species living on coastal shelves in the region. Richard meets British Antarctic Survey researcher Huw Griffiths to find out more.

Another report investigates the recent Icelandic volcano which presented scientists with a unique opportunity to study the ash cloud. Also, we hear how a ground-breaking study has revealed where giant sauropod dinosaurs preferred to live.

Finally, in an audio diary entry, a bird ecologist in Ireland explains exactly how to tag geese migrating to the Arctic.

This podcast is dated 26 April 2010.

NERC is a part of the Research Councils UK (RCUK) partnership of research councils.
