Scientists discovered a fascinating new deep sea animal they call the "mystery mollusc," and captured footage of the glowing nudibranch in its dark ocean habitat.

Science and exploration "are the two things that I'm more excited about in the world," according to "Titanic" director James Cameron. "I do those movies to get a little money so I can go do exploration. That's the fun stuff."

[Opinion column written by Paris Stefanoudis] Sunlit coral reefs are perhaps the most famous marine habitat and many people will have snorkelled over or dived down to one at some point. Home to a quarter of all known ocean life, these “rainforests of the ocean” have been at the forefront of marine research for decades […]

An underwater rover deployed by the Minderoo-UWA Deep-Sea Research Centre captured remarkable footage 3,300-meters down at the bottom of the Tonga Trench. It shows a rarely-seen bigfin squid (Magnapinna) "taking a walk" on its 13-foot tentacles. Watch below.

After five people perished on a controversial submersible dive to the wreckage of the Titanic in June, we got to thinking about what genuine undersea exploration looks like. In this episode, we speak with Tony Perrottet, who profiled the late OceanGate CEO Stockton Rush for Smithsonian magazine in 2019, about our ancient fascination with exploring hostile environments. Then we’re joined by Susan Casey, who has written four best-selling books about the ocean and its creatures, the newest of which is The Underworld: Journeys to the Depths of the Ocean. Susan tells us why understanding the ocean is key to humanity’s survival, and how, while serious research and shipwreck tourism may have some overlap, they remain two very different things.

Sea-floor nodules raise oxygen levels in the deep ocean, suggesting they may have a valuable role in ecosystems and adding to concerns about the impact of deep-sea mining

Let’s try and get you up to speed on the fascinating oddity that is simulation game Ecosystem, on the off chance that Nate's coverage of it hasn't stuck with you like an unwelcome brain parasite you’re nonetheless unwilling to get removed for fear of the lingering emptiness it might cause (he once described an eel as “a quaver with erectile dysfunction”). Broadly speaking, this game is Spore’s evolutionary-biology-degree-having cousin. It’s been in early access for about three years now, but with the latest "Crustacean" update, it’s just hit 1.0. Once again, carcinization has come for all things.

The importance of coral reefs in supporting diverse fish communities has been highlighted in a recent study. However, the effects of damaging fishing techniques were also observed in video footage of the reefs studied, located off the coast of Ireland.

Marine litter is a major issue in deep sea ecosystems in the Mediterranean Sea, new research confirms. A recent study shows that the total weight of litter found in these sensitive areas often equals, and even exceeds, that of the animals that live there. This work can provide a baseline for assessments of the impact of deep sea marine litter and to inform future policy reforms, the researchers suggest.

Deep sea explorers capture video of a rare encounter with a piglet squid, so named because it appears to have a snout.

Species is so rare that it hasn't been seen since an account in 1873.

It stretches for at least 85 miles and is likely the keystone source of the region's fisheries.

The ocean has deep secrets. It is a world as vibrant as the one outside. There is a unique ecology that defies common knowledge and often perplexes scientists. This barely-explored territory is also believed to hold vast quantities of precious metals and minerals that can sustain the modern world for centuries. So it is not […]

Pirate’s gold may not be that far off, as there are valuable metals embedded in potato-size nodules thousands of meters down in the depths of the ocean. Host Meagan Cantwell talks with Staff Writer Paul Voosen about the first deep-sea test of a bus-size machine designed to scoop up these nodules, and its potential impact on the surrounding ecosystem. In an expedition well above sea level, the Hayabusa2 spacecraft touched down on the asteroid Ryugu last month. And although the craft won’t return to Earth until 2020, researchers have learned a lot about Ryugu in the meantime. Meagan speaks with Seiji Sugita, a professor at the University of Tokyo and principal investigator of the Optical Navigation Camera of Hayabusa 2, about Ryugu’s parent body, and how this study can better inform future asteroid missions.
