But what makes the Ross Sea important is the vast sea of pack ice that in the spring and summer provides a wealth of phytoplankton and krill that supports what, till recently, has been a virtually intact near-shore ecosystem.
It's still heavy now, and it was heavy before that, but when you flipped open a newspaper, when you turned on the TV, it was about ice caps melting, wars going on around the world, earthquakes, hurricanes and an economy that was wobbling on the brink of collapse, and then eventually did collapse, and so many of us losing our homes, or our jobs, or our retirements, or our livelihoods.
I'll get some asshole at a watering hole asking what brand the ice is.
Driving them home, and they want them to be enlightened, so they take them to Ben & Jerry's ice cream company with its own foreign policy.
Then 10,000 years ago, exploiting a sudden change in global climate with the end of the last ice age, humans learned to farm.
That means that I use radar to study glaciers and ice sheets.
And like most glaciologists right now, I'm working on the problem of estimating how much the ice is going to contribute to sea level rise in the future.
This is produced using ice sheet and climate models.
So why can't we say with confidence whether or not a significant portion of a continent-scale ice sheet will or will not collapse?
And that's hard to know, because those processes and conditions are taking place beneath kilometers of ice, and satellites, like the one that produced this image, are blind to observe them.
In fact, we have much more comprehensive observations of the surface of Mars than we do of what's beneath the Antarctic ice sheet.
And in terms of time, we now know that ice sheets not only evolve over the timescale of millennia and centuries, but they're also changing over the scale of years and days.
So what we want is observations beneath kilometers of ice at the scale of a continent, and we want them all the time.
I said in the beginning that I was a radio glaciologist, and the reason that that's a thing is that airborne ice-penetrating radar is the main tool we have to see inside of ice sheets.
These are used to transmit radar signals down into the ice.
And the echos that come back contain information about what's happening inside and beneath the ice sheet.
And I think this is actually a misconception about this type of fieldwork, where people imagine scientists peering out the window, contemplating the landscape, its geologic context and the fate of the ice sheets.
This is a radargram, which is a vertical profile through the ice sheet, kind of like a slice of cake.
The bright layer on the top is the surface of the ice sheet, the bright layer on the bottom is the bedrock of the continent itself, and the layers in between are kind of like tree rings, in that they contain information about the history of the ice sheet.
And here we're peering through three kilometers of ice.
And there are sophisticated, interesting, electromagnetic reasons for that, but let's say for now that ice is basically the perfect target for radar, and radar is basically the perfect tool to study ice sheets.
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.
The red features are volcanoes or mountains; the areas that are blue would be open ocean if the ice sheet was removed.
It does not give us any indication of how the ice sheet is changing in time.
So that produced two million high-resolution images that my group is now working on analyzing and processing for comparing with contemporary conditions in the ice sheet.
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.
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.
And if we're going to do that, we're going to need totally new ways of observing the ice sheet.
But it turns out that detecting the reflection of the sun off the surface of the ocean and detecting the reflection off the bottom of an ice sheet are extremely geophysically similar.
