See the wonders of two newfound deep-sea coral reefs off the Galápagos

admin

Four decades ago, warm waters from an El Niño event killed off nearly all the corals surrounding the Galápagos. Most coral reefs never recovered (SN: 1/9/15). But in recent months, researchers have discovered vast landscapes of thriving corals in deeper waters surrounding the equatorial islands.

In April, scientists documented the first pristine deep coral reef found in the region, dubbed Cacho De Coral, which sits atop the ridge of an underwater volcano and stretches about 250 meters. On

How sea anemones living on deep-sea hydrothermal vents avoid metal poisoning

admin

Life near deep-sea hydrothermal vents can be pretty metal — literally.

In addition to crushing pressures, total darkness and scorching temperatures, poisonous plumes belch from beneath the Earth’s surface. Exhaust from these underwater chimneys contains particles of heavy metals like iron and manganese, which become toxic at high concentrations. But many animals cozy up next to these vents and form thriving communities, seemingly able to withstand the dangerous metals around them.

Now, researchers have a hint of how one creature

World nations debate future of deep-sea mining in Jamaica – EURACTIV.com

admin

Nations opposed to deep sea mineral mining and those in favor of exploiting the oceans’ depths butted heads in Jamaica on Wednesday (26 July), with both sides arguing their position would help protect the planet.

Members of the International Seabed Authority (ISA), a little-known global body tasked with regulating the vast ocean floor, are locked in a heated debate over the future of deep sea mining at their annual meeting in Kingston.

“We cannot and must not embark on a

5,000 deep-sea animals new to science turned up in ocean records

admin

More than 5,000 animal species previously unknown to science live in a pristine part of the deep sea.

Their home — called the Clarion-Clipperton Zone — sits in the central and eastern Pacific Ocean between Hawaii and Mexico. The zone is roughly twice the size of India, sits 4,000 to 6,000 meters deep and is largely a mystery, like much of the deep sea.

In a new study, scientists amassed and analyzed more than 100,000 published records of animals found

Satellite data reveal nearly 20,000 previously unknown deep-sea mountains

admin

The number of known mountains in Earth’s oceans has roughly doubled. Global satellite observations have revealed nearly 20,000 previously unknown seamounts, researchers report in the April Earth and Space Science.

Just as mountains tower over Earth’s surface, seamounts also rise above the ocean floor. The tallest mountain on Earth, as measured from base to peak, is Mauna Kea, which is part of the Hawaiian-Emperor Seamount Chain.

These underwater edifices are often hot spots of marine biodiversity (SN: 10/7/16)

Meet the bizarre ocean creatures discovered living near deep-sea volcanoes in the Indian Ocean 

admin

A new world of weird and wonderful creatures has been discovered living near deep sea volcanoes in the Indian Ocean.

Scientists from the Museums Victoria Research Institute returned from a 35-day expedition mapping the seafloor in Australia’s remote Cocos (Keeling) Islands Marine Park last week.

During their 6,800 mile (11,000 km) journey, they came face-to-face with a blind eel with gelatinous skin, and a hermaphrodite lizard fish with long sharp teeth.

They also encountered some adorable deep-sea batfishes which resemble
