the basic biology, ecology, and behavior of seabirds, the pro-gram now focuses on environmental variability and its rela-tionship to short- and long-term change in seabird popula-tions. Since 1987, the program has received interagency support from the National Science Foundation and the National Marine Fisheries Service, which together facilitate a coupled terrestrial-marine sampling program with a broad ecosystem perspective (Fraser et ale 1992b). In this article, we summarize the results of a recent analysis with direct rele-vance to ongoing investigations addressing the broader focus of this program. Changes in the populations of many southern ocean upper-trophic-Ievel predators, such as penguins and Whales, are thought to be ultimately linked to changes in the abun-dance of their primary prey, the antarctic krill Euphausia
