 A time capsule of satellite imagery of the earth will become available to scientists this month.

On June 28, digital imagery from more than three decades ago will be released by the Alaska Satellite Facility at the University of Alaska Fairbanks Geophysical Institute, NASA’s processor and distributor for this type of data. The images reveal an unprecedented view of sea ice, waves, forests, glaciers and more.

On the 5-mile snowmachine ride up to Point Barrow, we saw several fresh polar bear tracks the size of dinner plates, a pile of whalebones from last year, and a 3-foot-wide crack in the sea ice that could swallow a sled. The crack was created when an ice floe in the open water crashed into shore-fast ice.

Measuring the winds of space: UAF team prepares for 2014 launch

The sounding rocket released bright puffs of tri-methyl aluminum, which scientists track from the ground to study winds near the lower boundary of space. The streak on the bottom right is formed by chemicals that have been moved and distorted by winds and turbulence.

On a clear, cold night two winters ago in Fort Yukon, Carl Andersen watched a rocket he helped design pierce the upper atmosphere. He and three other scientists shot pictures as the rocket ejected bright puffs of chemicals in an inverted V formation more than 60 miles up.

“They were the brightest things in the sky,” Andersen said from his office at the University of Alaska Fairbanks.

Scientists respond to 70 plus eruptive events from Alaska volcanoes

Redoubt in 1990, courtesy AVO/USGS.Twenty-five years of monitoring and studying Alaska’s volcanoes by the Alaska Volcano Observatory have improved global understanding of how volcanoes work and how to live safely with volcanic eruptions. Timely warnings from AVO throughout its 25-year history have helped reduce the impact of erupting volcanoes, protecting lives, property, and economic well-being.
