Atmospheric Sciences
The Atmospheric Sciences group studies the physical, chemical and dynamical processes
of the atmosphere from the unique vantage point of the polar region. The group strives to understand
the polar atmosphere and its role within the Earth system. Many topics bear directly on societal issues
related to climate variability and change.

Space Physics and Aeronomy
The Space Physics & Aeronomy research group studies Earth's geospace environment,
which extends from the surface of the sun to Earth's atmosphere. The group uses
ground-based observations of magnetic fluctuations, infrasound, light from
auroral emissions, and radio signals reflected from ionospheric irregularities.

Snow, Ice and Permafrost
The Snow, Ice & Permafrost research group seeks to understand the properties of Earth's
icy regions, known as the cryosphere, and the physical processes that occur within them.
Scientists study the role of snow, ice and permafrost in shaping the landscape, and the
changes that occur as the Arctic climate warms.

Seismology and Geodesy
The Seismology group conducts research and monitors Alaska's earthquakes and tsunamis. The group
includes the State Seismology Lab. Alaska lies in a tectonically complex region bounded by a major
subduction zone. The group carries out high-resolution seismic recordings and studies the motion
and configuration of tectonic plates.

Tectonics and Sedimentation
The Tectonics & Sedimentation research group strives to reconstruct the processes of Earth's
history over a variety of timescales. Alaska and the adjacent regions of the circumpolar north
provide a rich environment for such research. The Pacific North American and Eurasian plates
meet in Alaska, creating a natural laboratory for research in this area.

Remote Sensing
The Remote Sensing group develops and uses data from satellite, ground-based and
airborne sources to address Earth and planetary science topics. The group studies
volcanology, sea ice, permafrost, crustal deformation, impact craters, land use and
hazard monitoring.

Volcanology
Alaska is the nation's most volcanically active state, with eruptions of broad impact. The Volcanology
group studies volcanoes and eruptions using remote sensing, infrasound, chemical analyses,
and special instrumentation. The group also studies volcanoes throughout the world and maintains
active collaborations with Alaska Volcano Observatory partners and with other universities worldwide.

ACUASI successfully tests parachute delivery with new drone

One of the University of Alaska Fairbanks’ two new twin-engine unmanned aircraft circled Nenana Municipal Airport, descended and turned toward a drop zone. Three medical payloads popped out of separate cargo doors in succession, drifting downward beneath their own parachute. It was the first time…

First rocket of 2026 takes flight at Poker Flat

A two-stage NASA sounding rocket shot skyward from Poker Flat Research Range at 4:20 a.m. today as part of a long-running project to learn more about aurora-produced nitric oxide in the upper atmosphere. Nitric oxide, a gas, can travel to lower atmospheric levels, where it can damage Earth’s…
