Read about carbon dioxide as a greenhouse gas, how its mixing ratio has varied over centuries and millenia. Have a look where it comes from and where it goes.

  Seasonal cycle of phytoplancton

Read about the growth periods of phytoplankton, which is another important sink of carbon dioxide and can be regarded in some way as 'forest of the ocean'.

 Diary of a field campaign

If you are interested in how research in the Finnish forest is really taking place, take a look at the diary of the QUEST field campaign in April 2005.
