Researchers have discovered high levels of biodiversity in deep-sea plains in the Eastern Pacific Ocean—an area that’s already been divvied up by mining companies for commercial exploration. The study, published today (October 17) in Current Biology, describes several new taxa of brittle stars, relatives of sea stars, and warns that industrial exploitation of the region could lead to serious declines in these and many other poorly documented species.

Prof Mat Upton is a medical microbiologist and Dr Kerry Howell is a deep-sea marine ecologist. At the University of Plymouth they have discovered antimicrobial properties in bacteria that live in a species of deep-sea sponge ­– a potential breakthrough in the fight against antibiotic-resistant superbugs. But they warn that such potential could be lost in the drive to exploit the ocean floor for minerals.

I’m on a ship 1,600 kilometres away from the nearest landmass. It has taken us five days to get from California to the middle of the equatorial Pacific Ocean. Our team sends a remotely operated vehicle 4.5 kilometres down to a flat abyssal plain that has never been explored by humans before.

The deep, cold waters off the rocky coast of Point Sur, California, are home to an unexpected community of organisms that most people associate with tropical settings—corals. Scientist Charlie Boch and his colleagues recently compared different methods to restore deep-sea coral by transplanting live coral fragments and measuring their survival rates. The experiment was conducted on Sur Ridge, 60 kilometers (37 miles) offshore and 800 to 1,300 meters (2,624 to 4,265 feet) below the ocean’s surface.

THE BOTTOM OF THE ATLANTIC OCEAN — Forty miles off the coast of North Carolina, the 274-foot research vessel Atlantis paced a dark, empty swath of ocean in evenly spaced lines as the crew pinged sound waves into the deep. A quarter-mile below, plumes of methane, a potent greenhouse gas, rose from the seafloor.

La viabilidad de la minería submarina de nódulos polimetálicos está siendo estudiada en la Costa Tropical por un grupo de científicos de diferentes ámbitos que se encuentran a bordo del buque oceanográfico Sarmiento de Gamboa, que durante los últimos 10 días se ha dejado ver por diferentes playas del litoral granadino.

Los metales que están siendo estudiados tienen una función crucial en las tecnologías innovadoras de Europa para la fabricación de aleaciones y baterías para automóviles eléctricos, sistemas fotovoltaicos y dispositivos para turbinas eólicas, entre otros productos.

It is completely dark, just above freezing cold and the pressure is crushing: this is the deep-sea floor. Food is very scarce in this huge region, yet a great diversity of animals have adapted to exploit and recycle resources and thrive within it.
