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 fromĀ 2003 to 2014, a period of rapid environmental change in the Arctic. Geostrophic currents around the Arctic basin increased in the lateĀ 2000s, with the largest increases observed in summer. More...

Vertebrate Palaeontology

dhead




Vertebrate palaeontology is the study of the fossil record of organisms with a backbone (Chordates). Vertebrate groups range from the first marine fish through the earliest air-breathing amphibians through to fully terrestrial reptiles and mammals.

A detailed examination of ancient vertebrate fossils can give us an insight to patterns of evolution, ecology and ontogeny as well as providing information through isotopic analysis of recent changes in climate.
