This year, at least seven 乐播传媒 alumni traveled to Antarctica to conduct or document research.
They spent the Antarctic summer, which is Maine鈥檚 winter, taking samples, transporting hundreds of tons of gear, or sticking cameras on the backs of seals. In doing so, they hope to uncover the secrets of Antarctica鈥檚 glaciers, fossils, and living mammals; what they find might teach us more about our world and beyond.

This is Part 1 of a series about 乐播传媒 alumni who spent this winter in Antarctica.
Part 2: If you give a seal a camera
Part 3: Fossils and beach volleyball on a glacier
Part 4: The secrets of the lakes
Each week in this series, we鈥檒l introduce you to different alumni and their projects, asking what it鈥檚 like to live and work on the bottom of the world.
Up first:聽Glaciers move, advance, and retreat over time. How does temperature affect their travel, and what can the last ice age tell us about today鈥檚 climate change?
In December and January, Brenda Hall 鈥�90 and Allie Balter 鈥�14 set off into a remote spot in the Transantarctic Mountains to find out. They spent weeks taking samples of rock and algae in an effort to figure out where the glaciers of 20,000 years ago went.
The question
鈥淲e鈥檙e interested in how the ice sheets there have changed in the past and how that relates to changes in climate over time,鈥� Balter says.
The team
Brenda Hall 鈥�90, a professor in the University of Maine School of Earth and Climate Sciences; Allie Balter 鈥�14, a graduate student in the same school; and two UMaine undergraduates, Laura Mattas and Tyler Pollock.

Balter became interested in the Arctic when Professor of Geology Mike Retelle took her on a research trip to Svalbard, above the Arctic Circle. The frozen Arctic sparked something: 鈥淚 decided I really loved glaciers and how climate has changed in the past.鈥�
Number of trips to Antarctica
For Balter, two. For Hall, 28.

The team set up three camps in the Royal Society Range in the Transantarctic Mountains, south of Australia and New Zealand. It鈥檚 one of the few places on Antarctica not covered by kilometers-thick layers of ice 鈥� but it used to be.
How to get there

Says Balter:聽鈥淔irst go you first go to Christchurch, New Zealand. You get your extreme cold weather gear, a big puffy red jacket and fleece pants.
鈥淭hen, you get on a plane along with other scientists. You go to McMurdo Station, the biggest U.S. research station. It鈥檚 kind of like a little town; there are a cafeteria, dorms, and places to get all your field equipment, tents, sampling equipment, and sleeping bags. You spend about a week there getting your gear for the field ready to go. There鈥檚 a bunch of trainings.
鈥淵ou then take a helicopter to the site in the mountains.鈥�
The research

Retreating glaciers are like conveyor belts, Balter says: Rocks and algae slide to the end of the glacier and are deposited in its trail, leaving records of where the glacier was. 鈥�9,000-year-old algae embedded in the sand give you a good idea of where the glacier used to be.鈥� By taking samples, the UMaine team hopes to determine how far a particular glacier advanced during the last ice age and how temperature correlates to the glacier鈥檚 movement.
The implication
鈥淭he end of the last ice age is a particularly good example of rapid global warming, and it may give us a better indication of what may happen to the ice sheet as our climate warms today,鈥� says Balter.
Antarctic living

The group slept in Scott tents, a style of tent that dates back to the first South Pole expeditions in 1912.
鈥淲e鈥檇 wake up at maybe 7 in the morning, make oatmeal for breakfast on our cookstove, and hike anywhere between two and 12 miles to take rock and algae samples,鈥� Balter says. 鈥淎t the end of the day, we鈥檒l carry all those back to our tent, and for dinner we鈥檇 have frozen meats and cheese and pasta.鈥�
The sound of silence

鈥淚f the wind鈥檚 not blowing, there鈥檚 no noise at all,鈥� Balter says. 鈥淭here are no animals and no trees and vegetation. It feels like you are on Mars.鈥�
And in some places, it鈥檚 not all that cold; temperatures hover at or above freezing during the Antarctic summer. 鈥淚t鈥檚 warmer there in January than it is in Maine,鈥� says Hall.
