A talk by Marianne Wootion on the work of the Continuous Plankton Recorder Survey

Marianne is Senior Analyst at the Continuous Plankton Recorder Survey, based in Plymouth, and Training Coordinator for the Global Alliance of CPR Surveys. The CPR Survey is the longest running, and most geographically expansive marine biological survey in the world. Marianne is co-author of a plankton guide to the North Atlantic.

Plankton play a key role in the oceanic food web, and may be a key indicator of changes in the ecosystem. Since 1957, the Continuous Plankton Recorder (CPR) has been towed over 6.5 million nautical miles in the North Atlantic and adjacent seas. The primary purpose of the CPR has been to record pelagic plankton, which it is has been doing so since 1931. Studies indicate a significant increase in microplastics from 1960–70 to 1980–1990.
