Starting on July 9, scientists led by Peter Wadhams of Cambridge University will work together with 3D scanning experts and engineers to capture the true shape of Arctic sea ice for the first time.

Greenpeace annouced this news in a statement. The team was due to leave on Friday for the icy north from the Norwegian archipelago of Svalbard.

Scientists will use a special submarine vehicle to measure underwater icebergs and surface laser scanners for the exposed parts.

The finished model will pinpoint pressure ridges and deformations resulting from the repeated melting and freezing of the ice.

"The emphasis on pressure ridges is because these ice deformation features -- which can be as much as 50 metres deep -- contain about half of the ice in the Arctic, yet have been shrinking in numbers and thickness much faster than the ice as a whole," said Wadhams.

"We need to see if they are melting, or disintegrating, or both."

"The Arctic Ocean is at threat from climate change, oil drilling and destructive fishing. It's time to draw a line in the ice and say you come no further to destructive industries profiting from a rapidly changing Arctic. The Arctic needs protection, not industry," said Frida Bengtsson, Arctic Campaigner for Greenpeace Nordic.

A number of celebrities including actors Hugh Grant and Penelope Cruz, entrepreneur Richard Branson and singer Paul McCartney have already signed a petition which will be placed at the North Pole.
