Guarding the Oceans

Scientists urge $2-3 billion study of ocean health

OSLO (Reuters) - Marine scientists called on Sunday for a $2-3 billion study of threats such as overfishing and climate change to the oceans, saying they were as little understood as the Moon.

A better network of satellites, tsunami monitors, drifting robotic probes or electronic tags on fish within a decade could also help lessen the impact of natural disasters, pollution or damaging algal blooms, they said.

"This is not pie in the sky ... it can be done," said Tony Haymet, director of the U.S. Scripps Institution of Oceanography and chairman of the Partnership for Observation of the Global Oceans (POGO).

He told Reuters that a further $2-3 billion would roughly match amounts already invested in ocean research, excluding more costly satellites. New technologies were cheaper and meant worldwide monitoring could now be possible.

"Silicon Valley has come to the oceans," said Jesse Ausubel, a director of the Census of Marine Life that is trying to describe life in the seas.
