My task for the day is to set stakes at every 100 meters in a straight line in a distinct orientation atop the sea ice over McMurdo Sound. Each flag represents a location for data collection about the sediments below the sea floor. Our goal of 8 kilometers a day is doable for our three-person team but not always pleasant in the Antarctic cold. My job of sighting each flag through a scope is tedious and requires stillness. In Antarctica stillness is not your friend. It is only in movement that you can find warmth at temperatures of -15 degrees Fahrenheit.

Me, completely bundled up. (This is my usual fashion out on the ice).

I bundle all the way up. Face mask, goggles, hat, glove liners, and gloves are all required on days full of stillness. The waiting and stillness required for this job make it my least favorite. So, I lose myself in the landscapes. As my two team mates chat between flags leaving me in limbo, I consider the millions of years it took for glaciers to carve out Ferrar Valley. I wonder what is causing Mt. Erebus to throw out plumes of smoke today as compared to only sputtering yesterday. I imagine all of the various sea critters nestled in grooves in the ice below my feet. I am struck by the daily realization that I stand and live atop the frozen ocean surface.

In the distance you can see icebergs that have been frozen within the sea ice.

The ice I live on moves like the crust of our planet. Our amazing planet spins as it zooms around the sun. All of this movement, yet I am still cold? These are the things you consider while trying to pass the time in Antarctica.

This is why I love science. Because it is about the value of perpetual questioning. Because at its core it is about considering and then reconsidering the facts. It is a constant and unyielding effort to find and reveal something that is more true. Even in science there are few truths but many partial ones. So, we hunt and we dig. We travel to the bottom of the world to gain more facts that we can consider and then reconsider. The power of science resides not in its answers but in the questions it provokes. Legendary scientists are remembered less for the answers they’ve given us and more for the questions they had the courage to ask. As I gaze out over the sharp shapes of white and blue and hear the buzzing of my radio calling me back to duty, I make note of these realizations. Walking back to my scope, I make a small promise to myself. “I promise to never lose sight of the power and potential of questions.”
