Arctic Sea Ice Animation

Surface currents under Arctic sea ice detected from space.

Monitoring the surface circulation of the ice-covered Arctic Ocean is generally limited in space, time or both. We present a new 12-year record of geostrophic currents at monthly resolution in the ice-covered and ice-free Arctic Ocean derived from satellite radar altimetry and characterise their seasonal to decadal variability from 2003 to 2014, a period of rapid environmental change in the Arctic. Geostrophic currents around the Arctic basin increased in the late 2000s, with the largest increases observed in summer. More...

Planetary Ices Group



The Planetary Ices Group carries out world leading research into the structure, dynamics and astrobiological potential of icy planetary bodies, with a particular focus on determining the properties of their constituent icy ‘minerals’. Planetary bodies are essentially crystalline aggregates: the structure and evolution of all such bodies are thus fundamentally due to the microscopic behaviour of the component crystals – equilibrium structures, elasticity, and transport properties for example. In determining the magnitudes of these properties for different ices and for the highly hydrated phases thought to exist in the interiors of outer solar-system moons we employ a coordinated multidisciplinary approach involving a combination of experimental and computational techniques.
