Massive Iceberg Could Alter Ocean Currents

Evidence of global warming? From Discovery News:

A massive iceberg struck Antarctica, dislodging another giant block of ice from a glacier, Australian and French scientists said Friday.

The two icebergs are drifting together about 62 to 93 miles (100 to 150 kilometers) off eastern Antarctica following the collision on Feb. 12 or 13, said Australian Antarctic Division glaciologist Neal Young.

“It gave it a pretty big nudge,” Young said of the 60-mile (97-kilometer) -long iceberg, about the size of Luxembourg, that collided with the giant floating Mertz Glacier and shaved off a new iceberg. “They are now floating right next to each other.”

The new iceberg is 48 miles (78 kilometers) long and about 24 miles (39 kilometers) wide and holds roughly the equivalent of a fifth of the world’s annual total water usage, Young told The Associated Press.

The iceberg that hit the Mertz Glacier is called B9B and had broken free from another part of Antarctica in 1987.

Giant Iceberg Heading For Australia

Bonnie Malkin in Sydney reports for the Telegraph:

A giant iceberg double the size of Sydney Harbour is on a slow but steady collision course with Australia, scientists have said.

The mammoth chunk of ice, which measures 12 miles long and five miles wide, was spotted floating close to the mainland by scientists at the Australian Antarctic Division (ADD).

Known as B17B, it is currently drifting 1,000 miles from Australia’s west coast and is moving gradually north with the ocean current and prevailing wind.

Dr Neal Young, a glaciologist working for the ADD, said that if the iceberg eventually reached Australia waters, it would crash into the continental shelf causing a magnitude three to to four tremor…
