NASA Captures Stunning Close-Up Photos of Antarctica's Massive Iceberg
Back in July, satellite images showed
an iceberg bigger than the state of Delaware
calving and drifting away from
Known as iceberg A-68, the gigantic slab of ice weighs about a trillion tons and features a surface area of 2,240 square miles (5,800 square kilometers). The berg is slowly drifting away from the Larsen C ice shelf, possibly heading towards the South Georgia and South Sandwich Islands. As it floats away from the Antarctic Peninsula, A-68 is splintering and forming more icebergs in the process .
This past Sunday November 12th, members of Operation Icebridge -a NASA-led initiative to produce detailed 3D maps of Antarctic and Arctic polar ice-flew a P-3 aircraft armed with a sophisticated array of measuring instruments to take a closer look.
"Perhaps you know the feeling: that moment when you see with your eyes something you have previously only seen in pictures," wrote
Hansen said she wasn't prepared for the enormity of the iceberg, as most bergs she's seen were relatively small and blocky.
"A-68 is so expansive it appears if it were still part of the ice shelf," she said. "But if you look far into the distance you can see a thin line of water between the iceberg and where the new front of the shelf begins. A small part of the flight today took us down the front of iceberg A-68, its towering edge reflecting in the dark Weddell Sea."
In addition to taking photos, the Operational Icebridge scientists sought to measure the depth of water below iceberg, which they did using radar and a
Scientists now have the clearest picture yet of A-68, which will help them track and study its progress moving forward.
