Artist Karen Romano Young explores some of the secrets of the Antarctic ice sheet and how science helps reveal them.

To the untrained eye, Arctic ice appears unchanging, but conditions can shift quickly, and often reveal life-threatening hazards when they do. It is an unforgiving environment, but the Inuit know how to navigate it. That knowledge has been passed down through generations, and a new app is giving centuries-old Inuit knowledge a very modern form.

When you think of ice, you might imagine glaciers, the North Pole, a clink in your water glass. But it turns out that our closest neighbor in space isn’t just a dusty ball—the moon has ice tucked away in deep craters at each of its poles. On top of that, scientists think the moon stole its ice: from comets, asteroids, maybe even from the Earth.

Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.

Anant Pande is an Indian polar researcher who studies snow petrels – shy pelagic (sea-faring) birds who nest on rock crevices in Antarctica. These endemic birds prefer to nest near less icy waters. Climate change has melted polar oceans and perhaps made it less energy intensive — as they have to fly shorter distances to find non-frozen oceans.

Glaciers around the world are melting because of climate change. Yet, while glaciers might be smaller than they once were, that’s not stopping tourists from flocking to see them.

Dive down into the freezing depths of Patricia Lake, in Alberta’s Jasper National Park, and you will find the wreck of the Habbakuk—a sixty-foot model battleship originally constructed of wood and ice.

Cool off from the summer heat with our next six-part miniseries all about ice – from those who call it home to its use as a tool in science.

Pacifica Sommers is an ecologist and explorer. From the deserts of Arizona to the Antarctic tundra, Pacifica has looked at how organisms from tardigrades to pocket mice live in extreme environments. We talked with her about some of the most beautiful places on Earth, the diversity of folks who can be scientists, and what exactly that bucket is for on the flight to Antarctica.

University of Washington biologist Kristin Laidre travels to the Arctic to study animals many of us have only seen in pictures. She has successfully tracked down the elusive narwhal and been up close and personal with a polar bear seeking to understand how the loss of sea ice and the effects of climate change are altering Arctic ecosystems.

In 1959, the United States built an unusual military base under the surface of the Greenland ice Sheet. Camp Century was a hub for scientific research, but it also doubled as a top-secret site for testing the feasibility of deploying nuclear missiles from the Arctic. When Camp Century was decommissioned in 1967, its infrastructure and waste were abandoned under the assumption they would be forever entombed beneath the colossal sheet of ice.

As we look back on 2020, we wanted to share some of the top news and views coming out of AGU.

Drilling engineer and ice core scientist Robert Mulvaney has driven thousands of kilometers over Antarctica in the past few years in a snow tractor, creeping slowly over one of the highest points of the ice sheet, near a location known as Dome C. He’s looking for the perfect place to drill one and a half million years into the past.

Earlier this year, scientists reported that radioactive fallout from nuclear accidents and weapons testing is present in ice sediments on the surface of glaciers in the Arctic, Iceland, the Alps, the Caucasus, British Columbia and Antarctica.

Many of the craters of Mars and Pluto feature relatively small ice islands unattached to their polar ice caps. These ice islands could be records of past climate change on Mars and Pluto, and could also provide clues about the workings of Martian water and ice, according to a new study in AGU’s Journal of Geophysical Research: Planets.

One of the most alluring parts of Earth and space science is that much of the key research takes place in the field, in some of the most incredible – and inhospitable – environments on the planet: on treacherous polar ice sheets, aboard sea tossed ships, at the mouths of active volcanoes, beneath turbid ocean waters, and atop the highest windswept peaks. Under these often less than ideal conditions, instruments …

Scientists Tackle Grand Challenges In the Earth and Space Sciences In New Special Centennial-Themed Collection
One hundred years ago when AGU was founded there were still large unmapped places on our planet and the idea of a person stepping on the moon was a dream. Discovery and wonder have characterized the last 100 years of science as we learned the plates shift, the climate changes, and scientists are studying the Moon, Mars, and beyond in detail. Our species now has a global view of how …

In 1911, two competing groups of explorers attempted to be the first to reach the South Pole. In this episode, atmospheric scientist Ryan Fogt recounts the journeys of Robert Falcon Scott and Roald Amundsen and discusses how extraordinary weather that year affected the two polar parties in vastly different ways.
