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
