DESCRIPTION:Meteorites are the only natural source of material from beyond
  the Earth\, providing invaluable evidence of how the Solar System formed 
 and evolved. Over 66% of the total classified meteorites to date have been
  found in Antarctica. However\, iron meteorites are under-sampled (0.7%) i
 n the Antarctic collection compared with worldwide meteorite falls (5.5%).
 \nThe team from the University of Manchester spent two austral summers in 
 Antarctica exploring new blue icefield areas for meteorites using several 
 methods. These included developing technology to identify sub-surface iron
  meteorites\, to test the hypothesis that iron-rich meteorites are likely 
 to lie buried a few cm below the surface\, as well as collecting meteorite
 s found at the surface.  36 meteorites recovered from the first field seas
 on are in the process of being classified\, with another 80+ meteorites fr
 om the second field season due back in the UK later this year. I will unve
 il some of the first images and data from these new samples.\n\n_Dr Jane M
 acArthur is a cosmochemist in the Department of Earth and Environmental Sc
 iences\, University of Manchester. She is curator of the first UK Antarcti
 c meteorite collection\, responsible for classifying all the meteorites re
 covered. Her research interests include analysing the first breccia meteor
 ite from Mars\, and the comparison of comet grains with chondrites\, to be
 tter understand mixing in the early Solar System._\n
