It established its Roi Baudoin Base scientific research station on the ice shelf in 1958, built for the International Geophysical Year (IGY), and decommissioned in 1967.
The ice shelf is being actively studied by Belgian Antarctic Program scientists from the Princess Elisabeth Base.
This includes: In early 2015, scientists announced the discovery of an almost circular structure in the ice surface, about 2 kilometres (1.2 mi) wide.
[7] The feature was discovered by German scientist Christian Müller as he conducted an aerial survey on 20 December 2014.
Initial analysis of satellite images indicates that the feature could have been present before the supposed impact,[10] even for 25 years.
