From the Ted Talk by Dustin Schroeder: How we look kilometers below the Antarctic ice sheet
Unscramble the Blue Letters
These are the flight lines of most of the modern airborne radar-sounding pferlois cecloetld over Antarctica. This is the result of heroic efforts over ddcaees by teams from a variety of countries and inaetatnnoril collaborations. And when you put those together, you get an image like this, which is what the continent of Antarctica would look like without all the ice on top. And you can really see the diversity of the continent in an image like this. The red fetraeus are vneacloos or mountains; the areas that are blue would be open ocean if the ice sheet was removed. This is that giant spatail scale. However, all of this that took decades to produce is just one snapshot of the subsurface. It does not give us any iaoiitcdnn of how the ice sheet is changing in time. Now, we're working on that, because it turns out that the very first radar observations of Antarctica were collected using 35 millimeter optical film. And there were thousands of reles of this film in the archives of the museum of the Scott ploar Research Institute at the University of Cambridge.

Original Text
These are the flight lines of most of the modern airborne radar-sounding profiles collected over Antarctica. This is the result of heroic efforts over decades by teams from a variety of countries and international collaborations. And when you put those together, you get an image like this, which is what the continent of Antarctica would look like without all the ice on top. And you can really see the diversity of the continent in an image like this. The red features are volcanoes or mountains; the areas that are blue would be open ocean if the ice sheet was removed. This is that giant spatial scale. However, all of this that took decades to produce is just one snapshot of the subsurface. It does not give us any indication of how the ice sheet is changing in time. Now, we're working on that, because it turns out that the very first radar observations of Antarctica were collected using 35 millimeter optical film. And there were thousands of reels of this film in the archives of the museum of the Scott Polar Research Institute at the University of Cambridge.
