Giant Antarctic iceberg A68a is not done yet

It might have suffered a big break-up this week, but the iceberg A68a is still carrying substantial bulk.The

latest satellite analysis indicates this Antarctic colossus maintains a

thickness that could yet see it catch in the waters surrounding the

South Atlantic island of South Georgia.If that happens, then worries about the effects the berg could have on the territory's wildlife will resurface.Penguins and seals might be obstructed as they forage for fish and krill.And these predators need to feed not only themselves, but their young as well. South Georgia is entering peak breeding season.
