Denman Glacier: Deepest point on land found in Antarctica - 3.5km below sea level!

[muriel_volestrangler]

The deepest point on continental Earth has been identified in East Antarctica, under Denman Glacier.

This ice-filled canyon reaches 3.5km (11,500ft) below sea level. Only in the ocean are the valleys deeper still.
...
For comparison, the lowest exposed land on Earth, at the Dead Sea shore, is just 413m (1,355ft) below sea level.
...
For the 20km-wide Denman Glacier, which flows towards the ocean in Queen Mary Land, this approach reveals the ice to be descending to over 3,500m below sea level.

There's a very good audio interview with Dr. Morlighem about halfway down the page.

That's way deeper than the continental shelf normally goes
