New SubCAS technology enables scientists to better study deep-sea ecosystems

Scientists at the California Academy of Sciences have created a new device that can capture and transport deep-sea  creatures to the  ocean ‘s surface without harming them, allowing scientists to better study the deep sea and potentially discover new species. The Submersible Chamber for Ascending Specimens, or SubCAS, works by first capturing wildlife within a small collecting jar. Once the SubCAS and its diver have ascended to approximately 200 feet below the surface, the jar is then moved into a larger chamber, which is sealed after an air bubble is also inserted. This air bubble expands as the pressure drops, which keeps the pressure within the jar at a constant level consistent with that experienced in the deep-sea creatures’ habitats. Until recently, technological challenges limited our knowledge of the mesophotic, or “middle light,” zone. The mesophotic ecosystems begin to exist roughly at the depth beyond which traditional diving technology ceased to effectively protect divers. On the other hand, this zone is also too shallow to justify the use of technology typically used for deep sea exploration. In the past decade, diving technology has improved, and with it our understanding of this unique part of the ocean.

The team has successfully brought 89 percent of captured mesophotic animals to the surface, while 143 of these creatures have been transported from locations all over the world to the Steinhart Aquarium in San Francisco , where many of them are on display in the Twilight Zone: Deep Reefs Revealed exhibit. “We’re showing a million-plus people a year these things nobody else will have the opportunity to see, and [using] that as a way to have a [conversation] about coral reef decline,” said Shepherd. The team is currently gearing up for a 2019 mesophotic expedition in the Indian Ocean. “There’s really nobody that’s done deep exploration diving on reefs in the Indian Ocean,” said Shepard. “We think we’re gonna find a ton of new species.” Via Earther Images via California Academy of Sciences

Mars Australia to go to 100% renewable energy in just over one year

One of the largest manufacturers in Australia is going green. Food company Mars Australia recently announced it will match 100 percent of its  electricity use with clean power by 2020. The company’s goal is to completely eliminate greenhouse gases from its operations by 2040. Exciting news from down under – Mars Australia has entered the solar system! We’re proud to announce we’re now purchasing the equivalent of 100% of our electricity use from #renewable #solar energy! Learn more about our commitment to a #sustainable future: https://t.co/BZnJSuCLkb pic.twitter.com/vofAZea3ht — Mars, Incorporated (@MarsGlobal) May 31, 2018 Mars Australia signed a 20-year power-purchase agreement with renewable energy company Total Eren. The Sydney Morning Herald reported the deal will support the Kiamal Solar Farm in northern Victoria, which Total Eren is developing, as well as a second clean power project in New South Wales. Mars Australia said it has contracted for power to match electricity needs of six factories and two sales offices in Australia. The company’s electricity use in the country is around 100 gigawatt-hours a year; general manager Barry O’Sullivan told The Sydney Morning Herald, “We’ve got a pretty big footprint on this planet. Our energy usage in total is equivalent to a small country’s.” Related: Australia’s solar energy capacity could almost double in one year Solar power from the Kiamal Solar Farm, which is slated for completion in the middle of 2019, won’t go directly to Mars Australia’s operations. Instead, it will go to the country’s national grid. Mars Australia will receive Renewable Energy Certifications from the Kiamal Solar Farm and will support Total Eren in expanding the farm to a planned 200-megawatt capacity. Mars Australia said the energy generated at the solar farm could power 185 million 180-gram (around 6-ounce) bags of peanut M&Ms, 2.5 billion packets of EXTRA gum, 1.4 billion bottles of MasterFoods tomato sauce or 29 million 3-kilogram (around 6-pound) bags of PEDIGREE dog food. We’re thrilled to announce that Mars Australia is adding new solar power to the national grid equivalent to 100% of our electricity use! But how much is that? Here’s a taste… pic.twitter.com/5HQurC9oUK — Mars, Incorporated (@MarsGlobal) May 31, 2018 O’Sullivan said in a Mars press release  that rising electricity prices played a role in the company’s decision to switch to renewable energy. The move joins Mars sites in the U.S., U.K. and about nine other countries. O’Sullivan said the “price volatility of energy in Australia made renewables the best option for our business.” Total Eren CEO David Corchia said, “Partnering with manufacturing thought leaders like Mars Australia is essential and sends a strong message to the rest of the market that now is the time to capitalize on the opportunities offered by renewable power purchase agreements and to drive positive changes in the environment .” + Mars Australia Via The Sydney Morning Herald Images via Depositphotos

Global Warming Traps Heat in the Deepest Regions of the Antarctic Ocean

  Photo © Shutterstock   Back in 1974, scientists used early satellite images to investigate a mysterious, ice-free region in the Antarctic sea called a polynya . Originally, researchers were perplexed when the are remained free of ice for three consecutive winters before freezing over — but a new study suggests that it’s the lack of an Antarctic polynya that’s a departure from the norm.

While snorkeling off the coast of Southern California, Jasmine Santana spotted something shimmering about 30 feet under the water. Santana, a marine science instructor from the Catalina Island Marine Institute , dove down to find the carcass of an 18-foot (5-meter) long oarfish lying beneath the water. She managed to drag it by the tail for more than 75 feet before 15 colleagues helped her finally bring the massive fish to shore.

More than 70 percent of our planet is covered with water, yet the oceans are still the most mysterious parts of the world. Earlier this year, deep-sea photographer and diver Yoji Ookata  discovered something he had never seen in his 50 years documenting the underwater world off the coast of Japan: a beautiful circular structure on the sand, about 80 feet below sea level that was so accurately carved that it looks like a deep-sea crop circle.

According to scientists, there are mussels at the bottom of the ocean that are efficiently converting hydrogen into energy in their very own, nature-made hydrogen fuel cells. The mussels, discovered by the Max Planck Institute of Marine Microbiology and the Cluster of Excellence (MARUM), were found near hydrothermal vents on the ocean floor and have onboard symbiotic bacteria that convert hydrogen into energy . With this discovery, researchers might be able to clone the hydrogen eating bacteria to create all-natural hydrogen fuel cells to power things other than sea life.
