Ice World Update: Marked Decrease in Arctic Pressure Ridges
In the Arctic, the old, multiyear ice is increasingly melting, dramatically reducing the frequency and size of pressure ridges. These ridges are created when ice floes press against each other […]

Marine Mineral Formations in the Arctic Ocean Challenge Existing Geologic Theories
A new study from USGS describes a previously unknown process of marine mineral formation in the Arctic Ocean, driven by frictional heating along tectonic faults rather than by hydrothermal activity.
