An enormous shark ”nursery” swarming with the predatory fish and strewn with their eggs has been found in the waters 200 miles off the western Irish coast.

The rare discovery was made by a remotely operated vehicle exploring the region’s cold-water coral reefs at depths of around 750m.

Scientists observed a large school of blackmouth catsharks, a relatively small species found throughout the northeast Atlantic, alongside the more unusual and solitary sailfin roughshark.

Most people are familiar with the ever-popular capelin or cod, but get up close and personal with three fish with creepy names and faces only a mother (fish?) could love.

Jane Adey, host of The Broadcast, got a peek in a Department of Fisheries and Oceans lab in St. John’s.

The deep sea angler is also known (more nefariously) as the northern sea devil.

Their squat bodies actually come in handy for their living conditions — this one was found 1,400 metres below the surface, according to Karen Dwyer, a fishery biologist with the Department of Fisheries and Oceans in St. John’s.

Almost 4,000 meters below the sea surface, in the southern Pescadero Basin, jagged ivory towers rise from the seafloor and emit hot shimmering fluid. They are the deepest known hydrothermal vents in the Gulf of California.

These deep-sea chimneys were discovered by MBARI scientists in 2015. The researchers call them the Auka vents. What’s intriguing is that these vents spew chemicals and host animals that are very different from those seen at Alarcón Rise, which is just 100 miles away.

Off the coast of Monterey, California, and some two miles below the surface of the Pacific Ocean, scientists piloting a remotely-operated submersible saw something no one has ever seen before.

Octopuses. Hundreds of them. Huddled on a rocky outcrop at the base of an underwater mountain.

“We went down the eastern flank of this small hill, and that’s when—boom—we just started seeing pockets of dozens here, dozens there, dozens everywhere,” says Chad King, chief scientist on the Exploration VesselNautilus.

South Africa has launched 20 new Marine Protected Areas (MPAs), that together cover an area two and a half times the size of the Kruger National Park, some 50,000 square kilometres.

After it was signed off last week by cabinet, 5% of South Africa’s waters are now protected areas, compared to 0.4% previously. This means that fishing won’t be allowed in these areas.

A so-described “ghostly” cephalopod put its deep-sea acrobatics on full display this week after it was captured by researchers in the Monterey Bay National Marine Sanctuary in what the team says is a previously unexplored area. The creature is part of a genus known as Grimpoteuthis and is sometimes referred to as a dumbo octopus on account of its fins that look similar to those of Disney’s iconic elephant.

The footage comes courtesy scientists aboard the E/V Nautilus, who beginning this week are in the area studying the underwater ecosystem around Davidson Seamount—a massive underwater mountain with coral forests that look like something straight out of Dr. Seuss book—at depths of up to 12,000 feet. The dumbo octopus was captured Tuesday by the team’s remote operated vehicles (ROVs) during its around-the-clock live feed of its exploration of the mountain’s diverse marine life.

Innovative research is uncovering previously unknown species in deep seas vulnerable to over-fishing, pollution and habitat destruction.

Oceans researcher and campaigner Alex Rogers first experienced the full visual impact of ocean plastic pollution in 2015: “I was diving in Honduras in 2015 at Utila in the Bay Islands and there were all these beautiful coral reefs, but as we came around the island we were faced with a raft of rubbish stretching out as far as you could see: plastic bottles, expanded polystyrene, fibreglass, every kind of human waste you could imagine … I have never witnessed such a huge quantity of debris. It was horrific.”

Not that it was his first brush with ocean plastic. That had come three years earlier, when he and his team were exploring seamounts in the Indian Ocean between Madagascar and Antarctica.

If you want deep sea footage to go viral, you have to give whatever creature you find a funny name. Blobfish, for example, are always popular—and now so is the ‘headless chicken monster,’ which is really a swimming sea cucumber (but sounds more interesting if you call it a headless chicken monster).

The United States Geological Survey reported that a magnitude 7.0 earthquake struck close to the proposed Solwara 1 deep sea mine near in Papua New Guinea yesterday at 7am local time. This follows a magnitude 6.6 quake nearby in March.

Dr. Helen Rosenbaum, of the Deep Sea Mining Campaign said: “Thankfully there have been no reports of damage or injury.  However, this is the second large earthquake this year right near the Solwara 1 deep sea mine proposed by Canadian company Nautilus.1 It’s also in the vicinity of several other exploration tenements in the Bismarck Sea between East New Britain and New Ireland Provinces that Nautilus aspires to turn into sea floor mines.”

Dr. Rosenbaum continued, “Can you imagine the damage and pollution that would occur if Solwara 1 and these other proposed deep sea mines become a reality?  Nautilus plans to have a 1.6 km long pipe moving ore slurry from the sea floor to the surface.  An Independent oceanographic assessment indicates that currents in Bismarck Sea would carry pollution from the Solwara 1 shorewards towards New Ireland province, the Duke of York Islands and possibly to the coast of East New Britain.2   

“Where are our emergency response plans?”‘ asks Jonathan Mesulam from the Alliance of Solwara Warriors3 and a local community leader whose village is located in New Ireland province, only 25km from the proposed Solwara 1 project.

“There is already great uncertainty about the environmental damage that will occur from the normal operation of Solwara 1. But such serious earthquakes will cause a catastrophe!  Nautilus’s equipment has never been tested under these extreme conditions. We have no capacity at either provincial or national level to deal with such an event.”

Jonathon Mesulam continued, ” Papua New Guinea sits right on the Pacific Ring of Fire.  What was our Government thinking by approving Solwara 1. And not only did they approve the project but they have also invested heavily to purchase a 15% stake in this experimental venture.  The company’s only credible shareholder Anglo American divested itself of this dodgy project in May and Nautilus’s share price has now hit an all-time low.4,5 Why is our National Government still backing this loser?”
