Census of Marine Life
A DECADE OF DISCOVERY
2,700 scientists
80+ nations
540 expeditions
US$ 650 million
2,600+ scientific publications
6,000+ potential new species
30 million distribution records and counting
These numbers only begin to describe the scope of the Census of Marine Life, a 10-year international effort undertaken in to assess the diversity (how many different kinds), distribution (where they live), and abundance (how many) of marine life—a task never before attempted on this scale. The Census stimulated the discipline of marine science by tackling these issues globally, and engaging some 2,700 scientists from around the globe, who participated in 540 expeditions and countless hours of land-based research. The scientific results were reported on October 4, 2010 at the Royal Institution in London.
The first Census of Marine Life produced the most comprehensive inventory of known marine life ever compiled and cataloged it as a basis for future research—30 million records as of January 2011 and counting! This first baseline picture of ocean life—past, present, and future—can be used to forecast, measure, and understand changes in the global marine environment, as well as to inform the management and conservation of marine resources. The Census investigated life in the global ocean from microbes to whales, from top to bottom, from pole to pole, bringing together the world’s preeminent marine biologists, who shared ideas, data, and results. During their 10 years of discovery, Census scientists discovered new species, habitats, and connections and unlocked many of the ocean’s long-held secrets. They found and formally described more than1, 200 new marine species, with another 5,000 or more in the pipeline awaiting formal description. They discovered areas in the ocean where animals congregate, from white shark cafés in the open ocean to an evening rush hour in the Mid-Atlantic Ridge to a shoal of fish the size of Manhattan off the coast of New Jersey, USA. They unearthed a rare biosphere in the microbial world, where scarce species lie in wait to become dominant if change goes their way, and found species believed to reside at both poles. While unlocking many secrets, investigators also documented long-term and widespread declines in marine life as well as resilience of the ocean in areas where recovery was apparent.
