Operated by the Marine Biological Association,

the Continuous Plankton Recorder (CPR) Survey

is one of the world's longest running

and most geographically extensive

marine ecological surveys

Guinness World Records
Towing since 1931 and over 9 decades of analysis

100’s of scientists around the world are using CPR data

The CPR Survey has now towed over 7.5 million nautical miles

We collect plankton coupled with ocean physical, chemical and biological observations

Our data are freely available and collaborations encouraged

Welcome to the CPR Survey

The Continuous Plankton Recorder (CPR) Survey is the most geographically extensive marine monitoring programme in the world. Started in 1931. Today the Survey is operated by the Marine Biological Association, based in Plymouth, UK.

Key Services

Marine biological datasets provide a wide range of environmental and climatic indicators to address marine environmental management issues such as Harmful Algal Blooms, pollution, climate change and fisheries

Research

At the base of the marine foodweb, the free floating plant life of the sea (phytoplankton) provide food for the animal plankton (zooplankton) which in turn provide food for many other marine organisms

Policy Makers

Policy drivers continue to influence research at the CPR Survey and an important aim of the organisation is to use CPR data and the expertise of Survey scientists to deliver evidence-based advice to policy makers and ecosystem managers

Data

The CPR Survey is unique in having comparable data on the geographical distribution, seasonal cycles and year-to-year changes in abundance of plankton over a large spatial area
