First, using one method of change detection analysis called the cumulative sum, it is possible to detect and characterize regime shifts along the California coast using sea surface temperatures (SSTs) and other variables. Second, physically-determined regime shifts and changes in ocean climatology, determined largely through detailed temperature time-series, can be linked to corresponding changes in biological communities, particularly phytoplankton, which exhibit rapid generation times.
