18-Ice: Ancient knowledge for modern tech
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.

16-Ice: Shells of an ice-less past
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.

Staff Picks: Chasing Narwhals
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.

Staff Picks: Toxic City Under the Ice
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.

CE12 – A Nuclear Legacy Buried in Ice
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.

Special Release: Deviations from the Norm
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 …

Centennial E6 – A Tale of Two Journeys
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.

E17 – Science Turns to Search and Rescue
The Arctic Ocean is topped with a layer of frozen sea water – sea ice – that grows every winter and shrinks every summer. To study the ice in detail, researchers hop aboard an icebreaker ship that can plow through the sharp, cold ice floes without being damaged.

E10 – Tracking Adorable Chainsaws
Northern fur seals spend more than half their lives at sea. But every summer, they congregate on the rocky, charcoal-colored beaches of Alaska’s Pribilof Islands to mate and give birth to tiny, black-furred pups. Researchers take advantage of the seals’ short time on land to learn more about them by placing GPS trackers on the seals’ bodies. But it’s not easy walking into a fur seal breeding colony full of aggressive, 500-pound males – not to mention getting close enough to attach a satellite tag.

The Dogs of Winter May Start Howling Again Soon.
There are growing signs that Arctic air may return to the U.S. by late next week as the mild weather pattern of the last ten days begins to fall apart. There is still a lot of uncertainty about whether or not this pattern will lock in or if this will be just a temporary blast of cold before milder Pacific air takes back over. The big clue to these changes is …

New research questions emerge from Arctic melting
By Alexandra Branscombe Originally posted on AGU GeoSpace WASHINGTON, DC – What is hidden within and beneath Arctic ice? Why does winter matter? What is being irretrievably lost as the Arctic changes? These are just some of the emerging questions that scientists are being challenged to answer about the rapidly changing Arctic in a new report, “The Arctic in the Anthropocene: Emerging Research Questions,” released last month by the National …

The Polar Vortex Gets Its 15 Minutes of Fame
Every science has its own language and terms, and meteorology has more than most. It’s strange though how every now and then, a scientific term you’d only hear if you were listening to a group of meteorologists discuss weather gets turned into a water cooler topic. In 2012, it was the term DERECHO (dah-ray show), when one came through the mid-Atlantic (and knocked down a million trees and power lines from Ohio all the way to the Eastern Shore of Maryland).
Now, the polar vortex has gotten its 15 minutes of fame. The cold outbreak at the beginning of the year was certainly one of the more severe chills in a couple of decades, but by no means as bad as what we saw during several winters in the1970’s and 1980’s. In the past few days I’ve seen images on TV news of snow, frozen lakes, and high winds that were labeled as the polar vortex, but they were wrong. The polar vortex is high above the surface and what you were seeing in those news reports was, (wait for it), snow, frozen lakes, and high winds!
While my fellow meteorologists have cringed as the public tries to make sense of this new word in the public’s weather dictionary, I think it’s a wonderful teaching moment. Albert Einstein said that science should be made as simple as possible, but no more so, and I cannot accurately explain the polar vortex in one sentence (or even one paragraph), but I can do it in three or four. So, if you will bear with me, I promise it will be quite interesting and you’ll never look at a TV weather report the same again!

Science Policy Conference: ARCUS Arctic Forum Highlights Interagency Collaboration
The Arctic Forum track organized by the Arctic Research Consortium of the U.S. (ARCUS) for the AGU Science Policy Conference will focus on interagency collaboration for arctic change research in the United States. Comprised of three sessions, all moderated by Dr. Brendan P. Kelly (Assistant Director for Polar Science, Office of Science and Technology Policy, Executive Office of the President), the Forum will include remarks by science program directors from …

Melting Ice and Burning Questions for the Future
As the climate changes, so do the impacts on society and the way we prepare for things such as severe weather, rising seas, droughts and wildfires, changing ecosystems, and melting glaciers. Looking at the world through the eye of a camera lens is one way that James Balog has been witnessing the impacts of climate change. One of his most recent works documents melting glaciers at various locations around …
