The Ocean: A Snapshot 2000-2010

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.

The first Census of Marine Life has concluded a decade of investigation into the whos, how manys, and wherefores of the denizens of the World Ocean and released their findings today.

While there’s debate over the costs of the enterprise ($650 million, $75 million of which came from the Sloan Foundation), I say: Money well spent.

The historic enterprise will almost certainly be followed by similar investigative decades in years to come, à la the International Polar Year. Science follows the footprints of past scientists, orienteering along maps of prior research, recalibrating the compass to current understanding.

The census includes the investigations of 2,700 researchers from 83 nations sailing aboard 540 expeditions to the farthest- and deepest-flung regions of our world.

The results have appeared in 2,600 scientific publications. Most of those are open access online. Here’s the bibliographic database.

The data are now available to everyone in more than 30 million records listed online in the Ocean Biogeographic Information System database. This database greatly contributes to a 21st-century trend of data sharing. A new scientific revolution.

Among the highlights of the census:

  • More than 1 million species likely inhabit our oceans, less than a quarter described by science and that’s not counting microbes, which potentially number in the hundreds of millions.
  • 6,000 possible new marine species were added to the catalogue of life on Earth
  • Formal scientific descriptions were made of more than 1,200 new species
  • 35,000 species were barcoded (genetically analyzed), an efforts that’s redrawn our understanding of the tree of life
  • Extremophile life turns out to be normal in marine habitats
  • Rare species turn out to be common in marine habitats
  • Even after a decade of intensive effort, for more than 20 percent of the ocean’s volume, the census database has no records whatsoever

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
