A group of scientists from the University of Kiel and the British Antarctic Survey (BAS) have managed to create a 3D map of Antarctica by working on satellite gravimetric mapping data as well as on data from the United States. seismological studies. In a study published in Scientific report they give details they have gathered on lost continents hidden under the Antarctic ice sheets. They used data collected by the European Space Agency's GOCE (Exploration of Gravimetric Circulation and Ocean Circulation) satellite, which operated between 2009 and 2013. This satellite was part of the project to study the attraction of gravity on the Earth. They used this information in combination with seismological data to reach conclusions. The research also revealed details of how Antarctica separated the ancient continent Gondwana, which was once part of the supercontinent Pangea.
The researchers pointed out that it was extremely difficult to conduct geological and geophysical studies in Antarctica because of the remoteness of the area and the thick layer of ice that covered it. This is why they had to proceed by reproducing 3D images of areas buried under thick layers of ice. This is where the gravimetric images of the GOSE project were useful. Fausto Ferraccioli of the BAS, one of the co-authors of the study, said that the gravimetric images of the project revolutionize the way we can study the least understood continent of the Earth.
He further explained that in eastern Antarctica they had discovered several geological features that brought out the similarities and differences between the Antarctic crust and the other continents connected to it (such as Australia and the subcontinent). Indian) up to 160 million years old. They also noted a similarity between the Earth's crust around Antarctica and the near-shore crust elsewhere. This indicates that the continent was connected to other continents and was part of the supercontinent Pangea. The results of the research support the hypothesis that 160 million years ago, all other continents were part of the same continent, which then fragmented and became unstable. is far away. The study will also help us understand the behavior of ice sheets when the sea temperature increases.
