Sastrugi are wind-driven snow shapes that resemble sand dunes. They may form on top of sea ice or land-based snow cover and can vary in size & complexity but often form parallel to prevailing wind direction. Find more cryosphere terms: nsidc.org/learn/cryosphere-g…

New insights into Antarctica’s shifting landscape:

The SCAR-endorsed GIANT-REGAIN project has released a new, consistent GNSS data set from 286 Antarctic sites. This resource will help scientists study bedrock movement, ice mass changes & sea-level rise. doi.org/10.5194/essd-17-1761…

Depending on who is using it and to what end, sea ice data can be misinterpreted & lead many to the wrong conclusions. On occasion, sea ice observations have even been shoehorned into disinformation campaigns about Earth’s climate & how it's changing. bit.ly/47hKbMl
