abstract: In the summer of 1973 in Adventdalen, spitzbergen (ϕ=78°15' lat., λ=17° to 15°30' long.) ecological studies of vascular plants were done. In particular, temperatures and radiation were measured over a 13-day period. In addition, plants and groups of plants were investigated according to the harvest method with respect to their biomasses and productivity. The caloric content of the plants was subsequently determined in the laboratory.In relation to other arctic areas, the area under study yielded higher productivity values, especially for grasses and grasslike plants. This is attributed to the special climatic position of the area.
