Iceberg-glacier collision could trigger climatic changes
An iceberg about the size of Luxembourg, which struck a glacier off Antarctica dislodging another massive block of ice, could lower oxygen levels in the world’s oceans, Australian and French scientists said on Friday. The two icebergs are now drifting together about 100 to 150 km off Antarctica, following the collision on February 12 or 13, said Australian Antarctic Division glaciologist Neal Young. “It gave it a pretty big nudge,” Mr. Young said of the 97- km-long iceberg 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 78 km long and about 39 km wide and holds roughly the equivalent of a fifth of the world’s annual total water usage, Mr. Young said.
