The Arctic Sea Ice Volume Anomaly time series is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) developed at APL/PSC.  Updates will be generated at approximately monthly intervals.

The Arctic Ocean is gaining open water each summer, with some scientists predicting that the warming planet will see an Arctic Ocean that’s completely ice-free in late summer by around the middle of this century.

This project will produce authoritative SAT data sets covering the Arctic Ocean from 1901 to present, which will be used to better understand Arctic climate change.

On Oct 1, 2021 after 12.5 years at the helm of PSC, Axel Schweiger stepped back from his role as Chair of PSC.  PSC sea ice researcher Bonnie Light has taken on the leadership role.   

Scientific American reports on a new study deriving ice thickness trends from measurements by the Polar Science Center’s Ron Lindsay and Axel Schweiger’s article published in The Cryosphere.

Increasing summer ice melt in the Arctic Ocean could shift global weather patterns and make polar waters more navigable. But scientists say forecasting Arctic ice and weather remains a massive challenge. The prospect of more ice-free water during Arctic Ocean summers has triggered efforts to improve ice and weather forecasts at the top of the world

UW Today talks with Qinghua Ding and Axel Schweiger about a new study published in Nature Climate Change of how natural variability affects sea ice loss in the Arctic. Ding, now a PSC affiliate, along with Schweiger and other colleagues from UW and NOAA used decades of data to examine the contribution of the atmospheric circulation to Arctic sea-ice variability.

Clouds play a major role in the arctic surface energy balance controlling the growth and melt of sea ice. At the same time the processes involved in the formation, maintenance and dissipation of cloud cover over the Arctic Ocean are thought to be strongly influenced by the sea ice itself. This project will advance the understanding of this interaction and feedback by asking: What is the response of Arctic clouds to diminishing sea ice?
