English: Gravity map of the Southern Ocean around the Antarctic continent
This gravity field was computed from sea-surface height measurements collected by the US Navy GEOSAT altimeter between March, 1985, and January, 1990. The high density GEOSAT Geodetic Mission data that lie south of 30 deg. S were declassified by the Navy in May of 1992 and contribute most of the fine-scale gravity information. The Antarctic continent itself is shaded in blue depending on the thickness of the ice sheet (blue shades in steps of 1000 m); light blue is shelf ice; gray lines are the major ice devides; pink spots are parts of the continent which are not covered by ice; gray areas have no data. Français : Carte gravimétrique de l'océan Austral et du continent antarctique Ce champ de gravité a été calculé à partir de mesures de hauteur des eaux de surface recueillies par l'altimètre de l'US Navy GEOSAT de Mars 1985 à Janvier 1990. Les données récolées par la mission "high density GEOSAT Geodetic Mission data" ont été déclassifiées par la Marine, en mai 1992 et fournissent la plupart des informations sur la gravité à petite échelle. Le continent antarctique lui-même est coloré en bleu selon l'épaisseur de la calotte glaciaire (Chaque nuances de bleu correspond à une étape de 1000 m) ; lignes grises matérialisent les bassins versants de glace; les taches roses sont les parties du continent qui ne sont pas couvertes par la glace, les zones grises sont celles pour lesquelles on manque de données |
