Marine biodiversity is measured by the number of species present inparticular marine ecosystems, or in the oceansas a whole. The Census of Marine Life programme was launched in 2000 to assess and explain the diversity, distribution and abundance of marine life. By 2010, the Census had discovered over6,000 potentially new species. From its findings, the Census extrapolated that there could be over one million species of marine life (excluding bacteria), the majority of which remain to be discovered.
