Growing cracks in an Antarctic ice shelf have forced the closure of a mobile British research station for a second winter, although it was relocated earlier this year to avoid the danger of being cast adrift.


It will be the second winter in a row that Halley VI has been shut for the season because of the danger that the station could be cut off by two growing cracks in the 490-foot-thick (150 meters) floating ice shelf.

Britain's Halley VI research station is being towed to a new location 
on an ice shelf in Antarctica, to avoid a growing chasm that 
threatens to cut it adrift. 


The eight modular buildings of the base are equipped with hydraulic legs 
and skis so they can be moved. But, this is the first time that the Halley VI 
base has been relocated since it was first assembled in 2012.
