Light climate and phytoplankton photosynthesis in maritime Antarctic lakes
Read more of: Light climate and phytoplankton photosynthesis in maritime Antarctic lakesThe responses of phytoplankton populations to seasonal changes in radiation flux in two Antarctic lakes with extensive winter ice-cover are described. A phytoplankton capable of photosynthesis was found throughout the […]

Large losses of total ozone in Antarctica reveal seasonal ClOx/NOx interaction
Read more of: Large losses of total ozone in Antarctica reveal seasonal ClOx/NOx interactionRecent attempts to consolidate assessments of the effect of human activities on stratospheric ozone (O3) using one-dimensional models for 30° N have suggested that perturbations of total O3 will remain […]
