Are Pacific Rim Marine Ecosystems Becoming More Variable (and Less Predictable)?

Changes in variance are infrequently examined in climate change ecology.  In this project, we are documenting changes in ecosystem variance of the North Pacific to provide insight into varying relationships between climate variables and ecosystem dynamics.  Specifically, physical (SST) and biological data from ecosystems of the Pacific Rim are being synthesized and investigated for changes in variance statistics (e.g., coefficient of variation, skewness) over the past 60 years.
