Commercial fishers are “bulldozing” ocean floors, says Greenpeace.

Its calculations show that in the 2017-2018 fishing season, New Zealand commercial fishing vessels destroyed up to 3000 tonnes of coral and other vulnerable species through bottom trawling.

A collaboration between researchers at the University of Hawai‘i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST), Hawai‘i Pacific University (HPU) and the National Oceanic and Atmospheric Administration (NOAA) revealed for the first time growth rates of deep-sea coral communities and the pattern of colonization by various species.

In the dark depths of the ocean, pretty much the only sources of light are the animals that live there. Whether flashing, glimmering, or emitting glowing liquids, many deep-sea animals are able to produce light (bioluminesce). MBARI researchers recently found that animals that live on the seafloor are much less likely to produce light than those swimming or drifting in the “midwater.”

Dean Grubbs thinks great white sharks are boring.

The veteran shark scientist, who has researched different shark species for 30 years, is vastly more intrigued by the little-seen dominant predator of the deep, dark, tropical and temperate oceans: the sixgill shark (most sharks have five gills).

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.
