caption_attribution_description: Deutsch: Bergung eines Meteoriten in der Antarktis durch Expeditionsmitglieder der U.S. Antarctic Search for Meteorites (ANSMET). Der Meteorit wird mit steriler Zange aufgenommen und in den sauberen Teflonbeutel gesteckt. Die Bergungsstelle wird vorübergehend durch einen Bambusstab mit der Feldnummer des Meteoriten markiert. Relevante Daten werden in ein Notizbuch geloggt, einschließlich Breiten- und Längenkoordinaten, die durch das GPS-Gerät an Bord des Motorschlittens bestimmt werden.. English: Recovery of a meteorite in Antarctica by members of the U.S. Antarctic Search for Meteorites (ANSMET) expedition. The meteorite is picked up with sterile tongs and put into the clean Teflon bag. The recovery site is marked, temporarily, by a bamboo flag pole with the meteorite's field number. Relevant data is logged into a notebook, including latitude and longitude coordinates acquired by the GPS unit onboard the Snowmobile. Español: Equipo recuperando un meteorito en la Antártida Français&#160;: Récupération d'une météorite en Antarctique par les membres de l'expédition de U.S. Antarctic Search for Meteorites (ANSMET). La météorite est prélevée avec des pinces stériles et mise dans un sac Teflon propre. Le site de récupération est temporairement marqué par un poteau en bambou avec le numéro de terrain de la météorite. Les données pertinentes sont enregistrées dans un ordinateur portatif, y compris les coordonnées de latitude et de longitude déterminées par l'unité GPS à bord de la motoneige.
context_page_description: ANSMET is a program funded by the Office of Polar Programs of the National Science Foundation that looks for meteorites in the Transantarctic Mountains. This geographical area serves as a collection point for meteorites that have originally fallen on the extensive high-altitude ice fields throughout Antarctica. Such meteorites are quickly covered by subsequent snowfall and begin a centuries-long journey traveling "downhill" across the Antarctic continent while embedded in a vast sheet of flowing ice. Portions of such flowing ice can be halted by natural barriers such as the Transantarctic Mountains. Subsequent wind erosion of the motionless ice brings trapped meteorites back to the surface once more where they may be collected. This process concentrates meteorites in a few specific areas to much higher concentrations than they are normally found everywhere else. The contrast of the dark meteorites against the white snow, and lack of terrestrial rocks on the ice, makes such meteorites relatively easy to find. However, the vast majority of such ice-embedded meteorites eventually slide undiscovered into the ocean.
