[Ed. – Technically, it would be the deepest KNOWN point. There may be a deeper one we haven’t discovered yet. 🙂 Exit question: might the new technology have been behaving unexpectedly because it didn’t like its silly name?]
A new study shows that the deepest point on land is under the Denman Glacier in East Antarctica. Glaciologists at the University of California, Irvine, were mapping the area only to find that the trough under the glacier went far deeper than they had imagined.
The trough is about 3.5 km (about 2 miles) below sea level but there is no ocean water there. Instead, it is filled with ice flowing from the interior of the ice sheet towards the coast. The trough measures about 100 km in length and is 20 km wide, according to the study. …
Morlighem and his team used a new technology called BedMachine to make this discovery. They developed a new generation ice sheet model but it was not behaving as expected.
