And as amazing as it is that we can look at what was hnaeippng under the ice sheet 50 years ago, this is still just one more snapshot. It doesn't give us observations of the vartiiaon at the annual or seasonal scale, that we know matters. There's some progress here, too. There are these recent ground-based radar systems that stay in one spot. So you take these radars and put them on the ice sheet and you bury a cache of car batteries. And you leave them out there for months or years at a time, and they send a pulse down into the ice sehet every so many minutes or hours. So this gives you ctnniouous oasbrtievon in time — but at one spot. So if you compare that imaging to the 2-D petrucis provided by the airplane, this is just one vtreical line. And this is pretty much where we are as a field right now. We can choose between good spatial coverage with airborne radar sounding and good temporal cgoareve in one spot with ground-based sounding.

And as amazing as it is that we can look at what was happening under the ice sheet 50 years ago, this is still just one more snapshot. It doesn't give us observations of the variation at the annual or seasonal scale, that we know matters. There's some progress here, too. There are these recent ground-based radar systems that stay in one spot. So you take these radars and put them on the ice sheet and you bury a cache of car batteries. And you leave them out there for months or years at a time, and they send a pulse down into the ice sheet every so many minutes or hours. So this gives you continuous observation in time — but at one spot. So if you compare that imaging to the 2-D pictures provided by the airplane, this is just one vertical line. And this is pretty much where we are as a field right now. We can choose between good spatial coverage with airborne radar sounding and good temporal coverage in one spot with ground-based sounding.
