This year is different.
The Montana State University scientist with an international reputation for polar research is spending his 24th season in Antarctica with no other researchers except the 17 members of his team. They're there for 2 1/2 months at the beginning of the coldest and darkest part of the year. During Antarctica's winter -- also called the "Polar Night" -- daylight disappears completely and temperatures can reach minus-55 degrees F.
He was looking forward to it, Priscu said before leaving Bozeman in January. He had been planning the trip for nine years and said it is vital.
He wants to get a more complete picture of what's happening in the lakes and liquid water that exist under Antarctica's glaciers, Priscu said. That's why he asked the National Science Foundation, which funds his research, if he could go at a different time of year. Spending a couple of months in Antarctica at the same time every year for decades is invaluable, but not good enough.
"Antarctica doesn't stop in the winter," Priscu said.
Priscu's team is working on several research projects, one of which is aimed at better understanding how microorganisms adapt to the loss of light. The researchers know that microbes stop converting sunlight into energy and start consuming organic carbon in the dark, but they want to learn more. The answers relate to global warming and carbon balance, Priscu said.
Priscu typically goes to Antarctica in October and returns in December. This year, he and Barbara Vaughn left Bozeman on Jan. 29 to get married in New Zealand. After their Feb. 5 wedding and a week-long honeymoon, Vaughn returned to Bozeman and Priscu continued on to Antarctica to join some of his team members already in Antarctica. This year's team includes former MSU students, as well as graduate students and postgraduate students from England, Scotland and Canada. Two members are undergraduate students. Eighty percent of the team is women.
One team member is Amy Chiuchiolo, an MSU research associate who has traveled to Antarctica six times in the past. Her latest trip ended right before Christmas.
"It's hard to go away every year for a couple of months, but it's fun," she said. "You can't beat doing field work."
The NSF supplies "extreme cold weather gear," which includes red parkas, hats, mittens, gloves and snow pants, Chiuchiolo said. She added that gloves get "pretty trashed" while drilling holes through 12 to 15 feet of ice to collect samples.
Priscu said his team members flew through New Zealand to Antarctica where they landed in a C-17 military transport airplane on a glacier about an hour away from McMurdo Station, the largest community in Antarctica. Large-tracked vehicles then took them to McMurdo where approximately 500 people provide support services. To collect and process samples, the team members fly by helicopter to field stations near the lakes in the McMurdo Dry Valleys, Transantarctic Mountains.
The field stations have one building where the researchers work with their samples, Priscu said. Diesel generators supply electricity. The researchers sleep in tents. To move around camp, they wear headlamps or carry flashlights when the auroras and the moon are not supplying light.
"I have never had to turn a light on before in the field camp," Chiuchiolo said. The sun shines 24 hours a day during the height of an Antarctic summer.
If conditions allow, the entire team will leave Antarctica on April 17, Priscu said. Priscu, 55, said he doesn't expect to return to Antarctica for another Polar Night. This one alone took almost a decade of planning.
"This is not an old man's game," he said.
He does plan to return as usual during the Antarctic summers.

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
