DESCRIPTION:In 1914-16 Ernest Shackleton led the 'Imperial Trans-Antarctic
  Expedition'\, aiming to make the first crossing of the Antarctic continen
 t (Weddell Sea to Ross Sea). He did not succeed\, and the expedition is re
 membered as a catalogue of disasters and bold escapes. But alongside the c
 haos and adventure\, some science was done - members of the expedition mad
 e many observations of the weather. These observations were never publishe
 d\, but have been preserved in the archives of the Scott Polar Research In
 stitute. To mark the centenary of the expedition\, we have digitised their
  weather observations\, assimilated them into the 20th Century Reanalysis\
 , and used them to investigate Antarctic climate variability over 100 year
 s.\n\nWe have learned a lot just from the records of this one expedition\,
  but to build a good dataset of long-term climate variability and change w
 e need to repeat this work with every voyage or expedition from which reco
 rds have survived: voyages of discovery\, scientific expeditions\, whaling
 \, fishing\, trading and military ships. And we need to do this not just f
 or the Antarctic\, but for the whole world. This is an enormous task\, but
  we are greatly helped by the contributions of 20\,000 volunteers working 
 through http://oldweather.org . This project has rescued the records from 
 the Jeannette expedition of 1879-81\, along with many more mundane voyages
 \, and is giving a new insight into Arctic climate change.\n
