Continuous Plankton Recorder in the omics era: from marine microbiome to global ocean observations

First routinely deployed in 1931 the Continuous Plankton Recorder (CPR) technology has established the most extensive, marine biological sampling programme in the world. With more than 90 years of sampling, over a total of 8 million nautical miles covered and 500 000 curated samples, the CPR survey provides a gold mine of information available to marine researchers. Such information is likely to exponentially increase thanks to new cutting-edge molecular technologies that are beginning to be applied on CPR samples. In this review we aim to address the exciting developments that the genomic revolution is having on ​CPR applications from the study of marine microbiome to ocean plankton communities leading to ​a new ‘digital era’ of the global ocean CPR observation programme.
