Un iceberg géant dérive en Antarctique

epa03956045 A handout picture made available by NASA on 19 November 2013 shows a giant iceberg, named B-31 by the US National Ice Center, estimated to be 35 km by 20 km or roughly the size of Singapore, taken on 13 November 2013 from the Landsat 8 satellite. B-31 in early November calved from Antarctica's Pine Island glacier (top) as the shelf of Pine Island Glacier has been moving forward at roughly four km per year. Such events happen about every five or six years, though Iceberg B-31 is about 50 percent larger than previous ones in this area. If Pine Island Bay clears of ice by the annual sea ice minimum in February???March, then Iceberg B-31 could move out into the Southern Ocean. EPA/NASA HANDOUT EDITORIAL USE ONLY
