Last week, Antarctica's Pine Island Glacier calved a massive iceberg, known as Iceberg B-46, into the Amundsen Sea. Pine Island has lost several large icebergs in the last few years -- it's one of the most rapidly melting glaciers in the Antarctic and a significant contributor to sea level rise.
NASA's Operation IceBridge flew over Pine Island Glacier on Nov. 7, capturing images and collecting data over the newly formed iceberg and remaining glacier.
