Standard Analysis and Visualization
of Plankton Time Series


COPEPODITE Time Series Methodology   <   COPEPODITE (main)

The standard zooplankton, phytoplankton, and microbial plankton time series analyses and graphical visualizations used by COPEPODITE were initially developed in-support-of and in-collaboration-with multiple SCOR and ICES plankton time series working groups.   At this time, a comprehensive "methods" document does not exist, but it is in the works.   Until this is available, we will redirect you to the reports and publications that use, contain, and describe these techniques.   The most recent of those reports is below:

A simple analysis for a complex data type.

The COPEPOD / COPEPODITE / WG125 / WGZE / WG137 / WGPME "standard time series analysis and visualization" methods are designed to allow for easy comparison of plankton (and other hydrographic variables) of different types, methods, and sampling frequencies (e.g., "biomass sampled three times per year" vs. "copepod abundance sampled weekly").   This is accomplished by looking at relative changes in the data values within a single time-series, relative to the long term average of those data, expressed as a unit-less ratio (or "anomaly").   A full summary of this method is summarized in O'Brien et al. 2013 and O'Brien et al. 2012, available via links above and below.
