Spear-toting robot can guard coral reefs against invasive lionfish
Lionfish are threats to not only fragile coral reef ecosystems, but the divers who keep them in check. They not only take advantage of unsuspecting fish populations, but carry poisonous spines that make them challenging to catch. Student researchers at Worcester Polytechnic Institute may have a solution: robotic guardians. They've crafted an autonomous robot (below) that can hunt lionfish without requiring a tethered operator that could harm the reefs.
Snapchat Lenses bring coral reefs to your neighborhood
How do you make nature exciting to a generation growing up with Snapchat and Instagram? The California Academy of Sciences has an idea: bring the nature to the apps that generation is using. It just trotted out a series of augmented reality Snapchat Lenses (the first of their kind, CAS said) that show reef life in your own corner of the world. You can get up close to creatures like sea turtles, nudibranches and moray eels without having to put on some diving gear or incurring the wrath of conservationists.
Researchers find coral reefs in a place they shouldn’t exist
While the waters of the North Atlantic and South Pacific tend to have what hard corals need to survive, the North Pacific doesn't, and it has been thought that deep-sea coral reefs were a near impossibility in that part of the ocean. But researchers at Florida State University and Texas A&M University have discovered a few reefs in the North Pacific that don't seem to be following the rules. Their findings were recently published in Scientific Reports.
Global coral bleaching event may finally be ending
For the last three years, coral reefs in the Atlantic, Pacific and Indian oceans have been devastated by bleaching due to high ocean temperatures. But now, after looking at satellite and model data, the NOAA says that this terrible event might finally be at an end.
Climate change could bleach most coral reefs within the century
The Great Barrier Reef's massive loss to coral bleaching last year might have been just a taste of things to come. According to a study by a team of marine scientists, 99 percent of the world's coral reefs could undergo severe coral bleaching before the century ends. The culprit? Climate change. When sea water in a certain location turns warmer than usual, corals in that area expel the algae living in their tissues, effectively turning them white. That's what bleaching is. It doesn't instantly kill the corals, but it makes them much more vulnerable to fatal diseases.
Researchers are building a robotic Lionfish exterminator
We joke around a lot about bringing about a horrific robot apocalypse, but let's get real: sometimes, building a killer robot is just the right thing to do. Well, at least when those robots are being used to cull invasive species. Researchers at Robots In Service of the Environment (RISE) are developing a robot to fight an invasive population of Lionfish that's threatening ecosystems off the coast of Florida as well as in the Caribbean and Bermuda.
Coral reefs will continue dying unless carbon output drops
Growing an endangered species of coral in a lab is one thing, but rebuilding a reef damaged by ocean acidification is a complete other. On paper, though, it's possible. A group of researchers attempted to counter the effects of rising carbon dioxide levels around Australia's Great Barrier Reef by pumping sodium hydroxide into lagoons that were isolated from the ocean during low tide, according to The Verge.
NASA to study the health of coral reefs across the world
Coral reefs are breathtaking homes for a diverse range of marine life, including turtles, sharks and eels. They're under threat from pollution, fishing and climate change though, and the data available on their deteriorating health is scattershot. To help, NASA is launching the Coral Reef Airborne Laboratory (CORAL) project, which will survey entire reef systems in Florida, Hawaii, Palau, the Mariana Islands and Australia. Airborne measurements will be taken with a Portable Remote Imaging Spectrometer (PRISM), which records the spectra of light reflected upwards by the ocean, and specifically the different signatures created by coral and algae.

An autonomous robot submarine is patrolling coral reefs and killing the starfish that normally eat coral, to preserve the reef. (So many conflicting feelings, amirite?) And MIT researchers are back with another 3D printer to blow your mind. This one is machine-vision enabled, meaning it can scan as it prints and correct itself.
Google dives deep to bring underwater photos of the Great Barrier Reef this September
Your next trip to the Great Barrier Reef could be from the comfort of your home now that Google's partnered with Catlin SeaView Survey, the University of Queensland's Global Change Institute and the Underwater Earth organization to document this amazing ecosystem. Equipped with a special underwater camera capable of withstanding depths of 328 feet, the survey aims to photograph 50,000 shots in 360-degree panoramic view and incorporate them into Google Earth and Google Maps. Dubbed "Google SeaView," it seeks to open opportunities for increased conservation as well as a free look for wanna-be world travelers who can't afford a plane ticket down under. As an added perk, the collected data may also be used to help future ship captains navigate through the treachery of the intricate coral highways. Check past the break for more info on the survey and plenty of footage teeming with aquatic wildlife.
