The Great Barrier Reef has been having a rough year. Warm waters have led to record coral bleaching this year and could hasten the reef’s die-off. But while surface corals are suffering, nearly a mile beneath the surface, deep-sea corals near the Great Barrier Reef are thriving.

Explosive volcanic eruptions are possible deep down in the sea — although the water masses exert enormous pressure there. An international team reports in the journal Nature Geoscience how this can happen.

What lies off Australia’s Great Barrier Reef, in the Coral Sea? The region was mostly unexplored and uncharted until a recent expedition searched its dark waters, uncovering an abundance of life, weird geologic features and spectacular deep corals. The deepest forays reached down more than a mile.

Mining on the sea floor should not begin before a full assessment of likely environmental impacts can be made, a report commissioned by the High Level Panel for a Sustainable Ocean Economy (Ocean Panel) said on Wednesday.

Living in an essentially zero-gravity environment, many deep-sea animals have evolved soft, gelatinous bodies and collect food using elaborate mucus filters. Until now, studying these delicate structures has been virtually impossible. A new study published in the journal Nature describes a unique laser-based system for constructing 3-D models of diaphanous marine animals and the mucus structures they secrete.

Explorers have captured video of the deepest-known octopus, revealing an adorably pudgy Dumbo octopus some 4.3 miles (6,957 meters) beneath the surface of the Indian Ocean swimming in what is called the hadal zone, where not even a drop of sunlight can penetrate.

The race for mining exploration of the seabed continues despite the moratorium requested by the Coalition for the Conservation of Deep Waters. Even countries that signed the Paris Agreement and active members of the UN are ready to explore those areas that man still does not know well.

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.
