Objective(s): To study the process of initial primary sucession following deglaciation of polar landscapes, including ecophysiological measurements on nitrogen fixing organisms; to sample willow plants fertilized in 1992 for secondary metabolites (a follow- up study; and to monitor permanent plots established in mesic tundra in 1992 as part of the International Tundra Experiment.

Project Description: The aim of the Sverdrup Pass Project is to learn how vegetation returned to the artic realm after the retreat of the continental ice sheet (8000 years ago) and the prospect of the land becoming green if climate warms. The Itex project is geared to the effect of climate warming on the vegetation. The snow-fence study at Baker Lake is concerned with the effects of long-lying snow deposited on both sides and its impact on the vegetation.
