algaes

To study such life, any undersea rover would need to be noninvasive.“While the thrusters of a normal underwater remote-operated vehicle can jet-blast delicate algaes off the bottom of ice sheets during close encounters, Bruie gently tiptoes beneath them,” said Daniel Arthur, a technologist who works with Caltech and the University of Western Australia.

"There is literally just a rock there, there's a couple of algaes, a few birds, a few seals and that's about it," Mr Hancock said.

A wide variety of fresh and salt water algaes are found in Chile, a South American nation with a long Pacific coast.

As the world population grows, and the climate changes, there’s been increased interest from nonprofits, businesses and development organizations to use algaes for food and energy.

Dead oceans mean dead people – either through famine, or, if the marine algaes that make 60-80% of the oxygen we breathe are also extinguished, through oxygen deficiency.
