P(論文) Twelve Adelie penguin rookeries were found in the ice-free areas on the Prince Olav Coast and the Soya Coast. The population size in each rookery was estimated based on the data collected by the personnel of Japanese Antarctic Research Expedition (JARE) and the authors. In the region surveyed by JARE, the total population of Adelie penguins in the rookeries was about 2000 to 3000. The distribution of the biomass of microalgae in soil was studied in Ongulkalven. The biomass was high around the presently used rookery and abandoned rookeries and in the wet parts of the depressions. The ratio of chlorophyll-α to the sum of chlorophyll-α and phaeophytin was high in the areas well supplied with melt water from the snow drifts. departmental bulletin paper
