East Antarctica’s Denman Glacier has retreated almost 3 miles over last 22 years

Irvine, Calif., March 23, 2020 – East Antarctica’s Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.

Greenland shed ice at unprecedented rate in 2019; Antarctica continues to lose mass

Irvine, Calif., March 18, 2020 – During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tons of ice, enough to raise global sea levels by 2.2 millimeters in two months. On the opposite pole, Antarctica continued to lose mass in the Amundsen Sea Embayment and Antarctic Peninsula but saw some relief in the form of increased snowfall in Queen Maud Land, in the eastern part of the continent.

Almost Alien: Antarctic Subglacial Lakes are Cold, Dark and Full of Secrets

More than half of the planet’s fresh water is in Antarctica. While most of it is frozen in the ice sheets, underneath the ice pools and streams of water flow into one another and into the Southern Ocean surrounding the continent. Understanding the movement of this water, and what is dissolved in it as solutes, reveals how carbon and nutrients from the land may support life in the coastal ocean.

Ultra-high energy events key to study of ghost particles

Physicists at Washington University in St. Louis have proposed a way to use data from ultra-high energy neutrinos to study interactions beyond the standard model of particle physics. The ‘Zee burst’ model leverages new data from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica and its future extensions.

SuperTIGER on its second prowl — 130,000 feet above Antarctica

A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch. SuperTIGER (Super Trans-Iron Galactic Element Recorder) is designed to measure the rare, heavy elements in cosmic rays that hold clues about their origins outside of the solar system.

Tip of the ICEBERG: Planetary scientists developing large-scale ‘imagery-computing superhighway’

Northern Arizona University assistant professor Mark Salvatore and doctoral student Helen Eifert are working on an NSF-funded project to analyze data across the frozen landscape of Antarctica, which will eventually help scientists produce detailed geologic maps of the Lower Colorado River Corridor.
