Biologists Have a Cosmic Explanation For Last Year’s Mysterious Sperm Whale Strandings

Last year brought what seemed like a disturbing omen to communities surrounding Europe’s North Sea: a whole lot of beached sperm whales. As Gizmodo reported at the time, the whales entered the sea’s shallow waters, where their internal sonar-like systems stopped working, causing them to become stranded and die. But scientists didn’t know why the whales entered these dangerous shallow waters in the first place. Read More >>

The Amazing Reason Deep Sea Corals Glow In the Dark

Lots of creatures glow in the ocean’s depths, where sunlight is slim to nil. But while most of these abyssal lightbulbs use their neon powers to hunt or avoid being hunted, deepwater corals may have beat everything else down there in terms of evolutionary creativity. New research indicates these corals glow in order to eat the meagre sunlight, turning their tissues into grow chambers that nourish tiny plants in a beam of artificial luminosity. Read More >>

The Oceans Are Getting Warmer Faster Than Anyone Realised

Great news, everyone! We’re getting better at measuring the changing temperature of the ocean. Unfortunately, the data shows that they are warming more rapidly than researchers thought. Read More >>

Swirling Underwater Fish Tornado Makes Sharknado Look Tame

As currents shift in the southeastern Pacific Ocean, they bring an abundance of nutrients and plankton to the region, luring predators of all sizes. Swarms of anchoveta arrive first for an easy meal, but soon find themselves having to come up with unique ways to fend off larger predators like sharks and tuna. The result should be familiar to fans of the popular B-movie Sharknado. Read More >>

This New Invisible Gel Robot Is a Stealthy Underwater Predator

As if the ocean wasn’t already full of nightmares, researchers at MIT have developed a soft and flexible robot made of hydrogel, a material composed mostly of water. The new bot is quick, strong, and almost completely invisible when submerged, allowing it to snatch up fish before they even realise they’re being tracked. Read More >>

Breathtaking New Video Footage of the Ocean’s Deepest Trench

Over thirteen thousand feet below the surface, hundred-foot hydrothermal vents spew black, 360 degree fluid like chimneys from the ocean floor. Tiny crabs, shrimp and limpets scuttle beneath the smokestacks, and a remotely-operated vehicle named SuBastian went down there recently to join them. Read More >>

We Just Found Out There Are ‘Bees’ in the Sea

In case you thought we’d figured out life in the oceans even a little bit, a new study published in Nature Communications sets the record straight. For the first time, scientists have found experimental evidence of underwater pollination. There are bees in the sea—or at least creatures that perform the same kind of work. Read More >>

The Sixth Mass Extinction Will Be Like Nothing in Earth’s History

The sixth mass extinction — the one that seven billion humans are sadly doing their utmost to trigger at this very moment — is shaping up to be like nothing our planet has ever seen. That’s the conclusion of a sweeping new analysis, which compared marine fossil records from Earth’s five previous mass extinction events to what’s happening in the oceans right now. Read More >>

A Volcanic Eruption Hid a Critical Climate Signal for Twenty Years

As our planet heats up, the pace of sea level rise is expected to quicken, making it harder for cities like Miami to stay above water. But since 1992, scientists have studied Earth’s mean sea level via satellites, and they’ve watched it rise at a steady 3 millimetres per year—no evidence for acceleration. Read More >>
