Anomalous polar absorption events detected by means of ionosondes at four stations in the northern hemisphere and four in the southern hemisphere have been compared with energetic particle events observed […]
The effects of variation in light intensity, temperature, and water content on rates of net photosynthesis and dark respiration have been investigated in two common tundra mosses, Polytrichum alpinum from […]
Satellite pictures have revealed the presence of ridges on the summits of ice rises in Antarctica. Because ice does not exhibit a critical stress it is conclugerd that these ridges […]
