| Unusual events and disturbances are important sources of variability in ecological data sets, but methods for their detection and analysis are not readily available. We have adapted widely-used quality control methods to identify and quantify unusual events in ten-year-long data sets from the relatively pristine North Inlet Estuary, South Carolina, USA.-Seasonal patterns and long-term trends were first removed from biweekly zooplankton and nekton abundance and corresponding water temperature and salinity data using nonparametic smoothing algorithms. The Shewhart Control Chart Method, a quantitative technique used for quality control in industrial manufacturing processes, was used to define four types of events according to intensity and duration.... |
