Faithful reproduction – Team at NICL processes replicate ice cores from WAIS Divide
The Antarctic Sun, Peter Rejcek

It's a scene that's been repeated for the last several summers in the Denver metro area: People bundled in thick coats, wool hats and heavy boots – as if ready for an arctic adventure – step into what appears to be a white-walled workshop. There are table saws and planers and less familiar instruments, including a device that sports electrodes.

This is the ice core processing room for the National Ice Core Laboratory at the Denver Federal Center in Lakewood, Colo., with an ambient temperature of minus 24 degrees Celsius.

National Ice Core Lab Stores Valuable Ancient Ice – Lab supplies Arctic, Antarctic ice cores critical to climate research
Science Nation, National Science Foundation

It's a freezing cold day inside the National Ice Core Laboratory (NICL) in Denver, Colo., as it is every day of the year. That's because the NICL is a facility for storing and studying ice cores recovered from the polar regions of the world. It's minus 23.3 degrees Celsius (minus 10 degrees Fahrenheit) inside, so everyone is bundled up in ski parkas, insulated gloves and boots. And, saws are buzzing, as scientists from all over the U.S. are measuring and cutting pieces of precious Antarctic glacier ice to take back to their labs for research.

Processed and packaged – Last cores from WAIS Divide borehole go through NICL
The Antarctic Sun, Peter Rejcek

It took a month to prepare for a week's worth of work at the National Ice Core Laboratory (NICL) in Lakewood, Colo. It was a long time in coming.

But the final sections of ice core from the West Antarctic Ice Sheet (WAIS) Divide were sliced and diced in mid-June, with samples of ancient ice destined for labs across the country to analyze the paleoclimate record. About 75 meters of ice were processed through NICL after the hole was deepened this past field season.

Getting to the Bottom – NICL team processes deepest ice from WAIS Divide project
The Antarctic Sun, Peter Rejcek

Mick Sternberg had literally made the same measurement a thousand times before. But this meter-long ice core was perhaps just a little more special. He double-checked his numbers on the final length, stood back, and rechecked again.

"No reason to rush through this," he said under his breath, which steamed out in the freezing temperatures of the National Ice Core Laboratory's processing room.

After all, this last section of ice, drilled from near the bottom of the West Antarctic Ice Sheet (WAIS) at a depth of about 3,331 meters, had been waiting around for a while. Probably somewhere in the neighborhood of 55,000 to 60,000 years

Trucked in – WAIS Divide ice cores arrive safely at NICL
The Antarctic Sun, Peter Rejcek

Talk about a road trip.

Three semi-trailer trucks, each pulling 20-foot-long refrigeration containers, rolled into Denver on March 15 after a 24-hr trip across the southwest corner of the country from Port Hueneme, Calif.

The cargo: ice. Lots of it - about 43 pallets' worth. But this isn't ice for some fancy cocktail party. The trucks from California had hauled Antarctic ice cores to the National Ice Core Laboratory (NICL) in Lakewood, Colo.

It was the final leg of a journey that had covered some 11,000 miles.

On the line – Researchers spend summer in deep-freeze to slice and dice WAIS Divide ice core
The Antarctic Sun, Peter Rejcek

It's midsummer in Denver, and the city has been baking under a heat wave for a couple of months. But in one small corner of the sprawling Denver Federal Center campus in the nearby suburb of Lakewood, about a dozen people are bundled up in thickly insulated Carhartt jumpsuits, wool caps, scarves and gloves.
