Six British Antarctic Survey stations were operational during the year. A new station, at Rothera Point, Adelaide Island, is being built to replace Adelaide station. Its development is providing a unique opportunity to study changes in the microbial, invertebrate, plant and birdpopulations as a result of human activities, including the inevitable atmospheric pollution and the localized influence of tracked vehicles. Several small sites have been set up to study these changes. Among the senior Survey staff to visit the bases this season were Dr R. M. Laws (Director), and Mr W. R. Piggott (Head of Atmospheric Sciences). Other visitors included Dr B.B. Roberts, Dr L. Ferraz, a Brazilian observer, and Mr D. Smith, a British artist.
