NASA Captures Images of Huge Iceberg’s Break Away From West Antarctica's Getz Ice Shelf
The American space agency NASA in March was able to capture the departure of a huge chunk of ice from Antarctica's majestic landscape.
NASA captured this remarkable event from the space. The monster iceberg, almost the size of the Manhattan, was spotted breaking away from West Antarctica's Getz Ice Shelf by the U. S. National Ice Center (NIC).
Experts said that glaciers in the Amundsen Sea of west Antarctica are losing ice cover much faster as compared to anywhere else on the continent. These glacier melt downs are also the major contributors to the rise of sea levels, they said.
Measuring nearly 17 miles (27km), the monster iceberg named B-34 appeared to have broken apart and moved out into the Amundsen Sea sometime in mid- to late-February 2015, NASA said.
The satellite images of this event were captured by the Moderate Resolution Imaging Spectroradiometer (Modis) on NASA's Terra and Aqua satellites took images spanning the calving event.
B-34 is the 34th iceberg from the 'B' quadrant of Antarctica to be tracked by the NIC. The new berg is still smaller, however, than the much older B-15T-a fragment of b-15 that initially broke off from the Ross Ice Shelf in March 2000.
Experts said that large icebergs can have large-scale impacts on the Southern Ocean. For example, as the bergs melt, addition of cold, fresh water to the saltwater ocean can affect ocean currents and circulation extremely.
Scientists further are looking forward to combine images such as this with noises recorded from icebergs to detect the different ways that glaciers lose ice into the oceans.
The study, based on satellite measurements between 1994 and 2012 by the European Space Agency, sheds new light on how Antarctic ice responds to climate change.
If the ice becomes too thin it would allow the permanent glaciers to slip into the ocean and start melting, sharply increasing the rise of ocean levels, said scientists.
