How will the Arctic respond to climate warming?

Ten days in the Big Tundra

How will the Arctic respond to climate warming?

Drs Viv Jones, Simon Turner and Nadia Solovieva have just returned from Arctic fieldwork, funded by NERC and the Department of Energy and Climate Change. They spent 10 days in the Bolshezemeskaya Tundra (= the Big Tundra), in an area NE of the coal-mining town of Vorkuta.

Normally, field work takes place in winter, when the ice-covered lakes provide a stable platform for sediment coring, so it was fascinating to see the tundra in summer, with its abundance of shrubs, herbs and birds, and to use boats to study the biology and chemistry of the lakes.

In addition to sediment coring, the team also deployed micro sieves, designed by colleagues at the radiocarbon laboratory at East Kilbride, to capture carbon dioxide. We hope that these can give some information about the age of the carbon released by permafrost melting.

The project is investigating how carbon has been stored in the lakes under different climate regimes, and providing information about how the arctic will respond to predicted climate warming.
