External Data Spec Published 26 Oct 2011
The CPR survey is the longest running, large-scale marine biological survey in the world. The CPR is a near-surface (10 m) plankton sampler voluntarily towed each month behind merchant ships on their normal routes of passage. Methods of analysis for 400 phyto and zooplankton taxa have remained almost unchanged since 1958.
