Continuous Plankton Recorder Observations

摘要

The Continuous Plankton Recorder (CPR) Survey has been towed monthly by commercial vessels to monitor the distribution of plankton in the surface waters of the Northeast Atlantic Ocean for over seventy years. In the past, between 1949 and 1981, CPRs were towed to Ocean Weather Station (OWS) Mike in the Norwegian Sea until sampling ceased due to financial constraints. Summary results from this early survey in the Norwegian Sea are outlined. We also discuss options for the resumption of monitoring of the surface plankton of the Norwegian Sea with CPR tows to OWS Mike and new routes around northern Norway and to Svalbard. In a climate change scenario, for assessment of ecosystems and fishery management an urgent need to improve monitoring of the plankton of Nordic Seas is identified.
