LTER Cross Site: Interactions between climate and nutrient cycling in arctic and subarctic tundras

Updated 2003-04-24

In this field project we will study vegetation characteristics along natural geographical gradients, and monitor vegetation dynamics in long-term field experiments. The measurements will be combined with remotely sensed images (i.e. satellite images) and computer models to quantify vegetation carbon exchange and to test whether these techniques are suitable to detect changes in the unique and vulnerable ecosystems of the arctic.﷡This summer a survey of leaf area indices along an east -west gradients of yearly rainfall and geography will be carried out, and one hillslope gradient and a small catchment will be studied in more detail. For each location leaf area estimates of the vegetation will be obtained using light measurements and the vegetation samples will be taken to be analysed in the lab.
