Oil-drilling worms and brittlestar cities: taking stock of life in the oceans

What lives in the sea? That question has been the singular focus of the Census of Marine Life, an ambitious 10-year survey, launched in 2000, that is reporting its findings at a Royal Society symposium in London today.

Of course, the project hasn’t catalogued all the life in the world’s oceans, but census has vastly increased our knowledge of the ocean biodiversity and filled in many gaps, its scientists say. Highlights profiled in last week’s Nature news feature on the project include a tubeworm that drills for oil at the bottom of the Gulf of Mexico, a ‘brittlestar city’ with tens of millions of the creatures living in close quarters atop a seamount south of New Zealand, and data – copious amounts of data.

Our feature also addresses the future of the census. The organization that provided a large chunk of the money to get the project started, the Sloan Foundation, has said all along that it isn’t ponying up for a second instalment, so census scientists are hoping other ocean-loving funders step in.


With all due to respect to the Harper’s Index, here is the Census of Marine Life by the numbers:

2700 – Scientists involved

9000 – Days at sea scientists spent on 540 expeditions

2600 Research papers produced

28,000,000 – Observations collected in a database created for the census

650,000,000 – Global investment in US dollars

1,000,000 – Estimated number of species in the ocean, excluding microbes

250,000 – Species formally described in the literature

1200 – New species described by census scientists since 2000

5000 – Estimated number of new species collected during the census not yet described

18,000,000 – Microbial DNA sequences collected

    And how many of those 2600 papers were published in Nature?

    Very few.

    Nature ms editors seem to go weak at the knees for any abstruse new gene or gene function. But fundamental field biology, involving observation-based discovery, seems to be out-of-favour in the Kings Cross offices.

    Perhaps a reminder to staff about the title of your journal is in order?
