THE OCEAN CLEANUP

Speaking of Science

QUOTES

I would like to have eyes on

the deep ocean when hurricanes

come b y, that would be great

to know.

— Rut Pedrosa Pàmies, marine biogeochemist and

coauthor of a recently published study that suggested

that hurricanes alter the oceans’ “biological pump” by

increasing the export of organic materials from the

surface to greater depths (Wired, October 4)

Our ocean cleanup system is

now finally catching plastic,

from one-ton ghost nets to tiny

microplastics! Also, anyone

missing a wheel?

—A tweet fromBoyan Slat, CEO and founder of The Ocean

Cleanup project, a nonprofi t that launched a 600-meter-

long device designed to collect refuse from the Great Pacifi c

Garbage Patch (October 2)
