  • Cryosat European Space Agencys Ice Mission

    06.09.2005

    European Space Agency's CryoSat mission is dedicated to monitoring precise changes in the thickness of polar ice sheets and floating sea ice over a 3-year period.

  • The Drake Passage Channel Deepening the Antarctic Chill

    05.09.2005

    A new analysis of marine geophysical data conducted by British Antarctic Survey (BAS) scientists reveals that South America and Antarctica split apart very rapidly in geological time, forming the Drake Passage. This eventually led to the formation of the Antarctic Circumpolar Current, the world's largest deep current (transporting some 130…

  • New Study Provides Further Evidence Ozone Layer No Longer in Decline

    31.08.2005

    A collaborative study involving researchers from University of Colorado at Boulder, National Oceanic & Atmospheric Administration (NOAA), the University of Wisconsin Madison, the University of Chicago and the University of Illinois indicates Earth's ozone layer, while still severely depleted, is no longer in decline. This study is based on long-term…

  • World Officials Say Action Must Be Taken against Global Warming

    24.08.2005

    Environmental ministers and other officials from 23 countries met in the Arctic town of Ilulissat (Greenland), and agreed that nations must take action against global warming. However, the conference took no decisions on how to fight global warming.

  • Ice Melting in the Arctic Is Increasing

    24.08.2005

    A report issued by the Arctic System Science Committee in the framework of the Arctic System Science program of the National Science Foundation (USA) states that ice melting in the Arctic is increasing and that no known natural process is likely to change that trend.

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.
