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

Operating since 1931, the Continuous Plankton Recorder (CPR) survey is recognised as the longest sustained and geographically most extensive marine biological survey in the world. The dataset comprises a uniquely large record of marine biodiversity covering ~800 taxa over multi-decadal periods. In terms of our scientific understanding of natural variability and human-induced change on our oceans, the CPR survey is of global importance and it is used by scientists, policy makers and environmental managers across the world. The data is used to examine strategically important science pillars such as climate change, human health, fisheries, biodiversity, pathogens, invasive species, ocean acidification and natural capital. The results have included the globally first documented studies of large-scale ecological regime shifts, and of biogeographic, phenological and trans-arctic migrations in the marine environment in response to climate change.

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 252,385 records. 2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
