BIG BLUE EQUALS BIG UNKNOWN
Even after 540 Census of Marine Life expeditions to countless corners of the Earth, more than 20 percent of the oceans remain totally unexplored, organizers say.
And though it’s brought the tally of estimated known marine species from 230,000 to 250,000, census scientists “still could not reliably estimate the total number of species, the kinds of life, known and unknown, in the ocean,” according to a press statement. They do say, though, that a million species is a fair guess.
Knowlton, co-director of the Census of Coral Reefs, a field project of the census, said, “As well as chipping away at the unknown and turning it into the known, the census also gives us a sense of the scale of the unknown.”
