    Following its coverage of the 25th Chinese National Antarctic Research Expedition (CHINARE 25), SciencePoles caught up with Chinese Arctic and Antarctic Administration (CAA), to hear about the goals of the 26th CHINARE expedition and China's future polar research plans, including the construction of a new research ice breaker.

    Polar Ice: The Essentials

    21.06.2005

    Although polar ice might appear homogenous it is in fact surprisingly diverse, often prompting queries about the differences between the various types of ice found in the polar regions.

Latest Pictures

  • The JARE-51/BELARE-SAMBA meteorite search program recovered a possible ureilite of 150-200 g (here next to a Gundam scale model of ~12 cm high). This rare type of meteorite is an achondrite (a stony meteorite from the mantle of a different planetoid), only known through similar Antarctic meteorite recovery programs.
  • Another view on the possible ureilite, in the field it is very difficult to distinguish from more common types of meteorite, such as ordinary chondrites. Ureilites are the third rarest type of meteorite after aubrites and diogenites.
  • Although a rather inauspicious specimen on first looks, this fragment is an iron meteorite originating from the deep core of a former small planet. The fusion crust is not as black as found for other meteorites, while the density is a lot higher.
  • Frontal view on the Shirase, the Japanese icebreaker that transported our team from Australia to Crown Bay, Antarctica where the journey to the eastern Sør Rondane Mountains began.
  • Meteorites and the traps in which they are caught are generally widespread in the Antarctic. To get the highest recovery, snow mobiles are used. For this mission, generally a V-shaped formation was applied with 15 to 25 m between each member of the search party. In this way, the explored surface area can easily reach 15 km2 per day.
  • Two pieces of a fragmented meteorite, exposed to the air long enough to be weathered and broken.
