NASA researchers using Air Campaigns to study Arctic ClimateWritten by Alan Buis
NASA researchers this summer and fall are carrying out three Alaska-based airborne research campaigns aimed at measuring greenhouse gas concentrations near Earth’s surface, monitoring Alaskan glaciers, and collecting data on Arctic sea ice and clouds. Observations from these NASA campaigns will give researchers a better understanding of how the Arctic is responding to rising temperatures. ![]() Changes in more than 130 Alaskan glaciers are being surveyed by scientists at the University of Alaska-Fairbanks in a DHC-3 Otter as part of NASA’s multi-year Operation IceBridge.

NASA asks “Is a Sleeping Climate Giant Stirring in the Arctic?”
On the horizon, a long, dark line appears. The plane draws nearer, and the mysterious object reveals itself to be a massive herd of migrating caribou, stretching for miles. It’s a sight Miller won’t soon forget. ![]() Permafrost zones occupy nearly a quarter of the exposed land area of the Northern Hemisphere. NASA’s Carbon in Arctic Reservoirs Vulnerability Experiment is probing deep into the frozen lands above the Arctic Circle in Alaska to measure emissions of the greenhouse gases carbon dioxide and methane from thawing permafrost – signals that may hold a key to Earth’s climate future.

Soldiers train on LCLA before deploymentby Pfc. Donte’ Gordon, 101st Sustainment Brigade
The Low Cost, Low Altitude, or LCLA, aerial delivery system allows Soldiers to deliver supplies without the inherent risks that ground convoys face. It uses a Sherpa C-23 aircraft, and is able to drop supplies directly into a Forward Operating Base. Specialist Gregory Searcy, transportation management NCO of 129th CSSB, said this was the first time he had ever conducted Aerial Delivery training. “You can deliver more supplies to Soldiers by using a method of travel by land, especially having multiple trucks that are able to ship more supplies,” he said. ![]() Soldiers with the 129th Combat Sustainment Support Battalion, 101st Sustainment Brigade, watch as bundles from the C-23 Sherpa aircraft are pushed out. The Soldiers took part in the Low Cost, Low Altitude Aerial Delivery training to find a safe and reliable method of deliver supplies to Coalition Forces. (Photo by PFC. Donte’ Gordon - 101st Sust.
