The ice shelf itself floats over almost 3, feet m of water, making the project even more challenging. Satellite imaging has also made it easier to trace modern-day changes in Antarctic ice. The European satellite Envisat, for example, has been documenting the loss of ice from the Larsen ice shelf for more than a decade.

Many researchers custom-build their own technology to fit their scientific needs. Custom-built cameras can photograph the water column from onboard research vessels, said Cassandra Brooks, a doctoral student from Stanford University who recently returned from a National Science Foundation expedition aboard the icebreaker Nathanial B. The Stanford researchers, meanwhile, used specially designed onboard lab equipment to measure dissolved carbon in the water. On the other hand, sometimes the best technology is whatever is on hand.

During the voyage, Brooks said, the scientists noticed that some of the pancake ice on the Ross Sea was unexpectedly glowing green — a sign of an unusually late phytoplankton bloom. No one had planned to study this unexpected phenomenon, but that doesn't mean the researchers were about to let the opportunity pass them by. Original article on LiveScience.

This worked well when the men were at base camp and conditions were dry. However, if the sleeping bags got wet or iced up, they soon became stiff and heavy to carry. Apsley Cherry-Garrad described the sleeping bags in his book 'The worst journey in the world', first published in The sledges were made of wood, leather, and rope.

The conservation team at the Scott Polar Institute in Cambridge is currently conserving some of the sledges and other equipment used on the British Antarctic Expedition. You can find out more about this process on the Scott Polar Institute blog.

Special snow shoes were made for Scott's team of Siberian ponies. Using a circle of wire for the base, the shoes were created from bamboo, and were fitted to the ponies with leather straps. Enough shoes were transported for all of the ponies. However, before the initial depot laying expedition in , there was not enough time to train the ponies in their use. Scott was not convinced that they would be effective, and only one pair was taken on the journey. The ponies had great difficulty walking in the snow, and the one available pair of snow shoes proved to be invaluable when tried out on one pony, Weary Willie.

Scott regretted having left the other pairs at Cape Evans, as the slow progress of the ponies had an adverse impact on the success of the depot laying expedition.

Meares and Wilson were sent back to the base to collect more of the pony snow shoes. Unfortunately by that time, the ice had broken up and it was impossible to retrieve the shoes.
