Arctic sea ice level recovery in 2014

 Despite a well-documented ~40% decline in summer Arctic sea ice extent since the late 1970’s, it has been difficult to estimate trends in sea ice volume because thickness observations have been spatially incomplete and temporally sporadic. While numerical models suggest that the decline in extent has been accompanied by a reduction in volume, there is considerable disagreement over the rate at which this has occurred.

Vertebrate Palaeontology

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.
