Human activity has been wreaking havoc on ocean life. One group however seems to thrive where others struggle to survive: new evidence shows that cephalopods’ numbers have significantly increased over the last six decades.
Eelume company developed a snake-like robot for underwater maintenance tasks. The deceptively simple robots could drastically reduce operating costs for deep sea rigs.
Plastic bags, bottle caps and plastic fibres are among the myriad of micro plastic debris that wash out into the Pacific Ocean. These get ingested by the marine life like fish, mammals and birds which are dying from choking, intestinal blockage and starvation. Moreover, some are toxic pollutants that are absorbed, transported, and consumed in the food chain eventually reaching humans. The most effective way to contain microplastics is to raise floating nets around Asia’s coats, not around the Great Pacific Garbage patch, researchers reckon.
New imaging techniques might revolutionize the technologies currently used to capture uranium from seawater, as researchers gain a better understanding of the way the compounds that bind the atoms interact with them.
You’d think there’s not much a little fish can do to hide from predators in open waters. But when rocks, algae and other marine nooks and crannies are nowhere to be found, fish turn to manipulate the physical interactions of light to balance the scale. For instance, some open ocean fish species employ specialized skin cells that reflect polarized light. This reflection is most effective, not coincidentally, at the ‘chase angle’ or from the predator’s point of view. It’s so effective that the US Navy is funding work that might shed light how exactly some fish do this and how this can be applied to make submersibles equally inconspicuous.
Ocean acidification, one of the often ignored dangers associated with climate change is becoming increasingly worrying. As our climate becomes hotter and hotter, the oceans become more and more acidic, and this threatens some animals’ ability to create and maintain carbonatic shells.
In what’s perhaps one of the most amazing marine science study, a team of researchers scoured the world’s oceans fishing for microbes, viruses and other tiny life during a three and a half year trip aboard a schooner. The trip was long and arduous for sure, but ultimately it paid out – big time! The team collected 35,000 samples at 210 stations over the voyage, and found 35,000 species of bacteria, 5,000 new viruses and 150,000 single-celled plants and creatures. Most of these are new to science. Only a small fraction of the newly discovered and known species alike had been genetically sequenced, but results so far show just how interconnected and symbiotic marine life is. It also means it’s also vulnerable in the face of environmental changes, particularly climate change.
MIT researchers deployed intricate contraptions, including cables that run to the sea floor and an autonomous submarine, to measure internal weaves around the South China Sea. The researchers followed and measured these waves from their origin, until they dissipated, and in doing so have recorded the “largest waves documented in the global oceans.”
We all know that our oceans are polluted, and one of the biggest problems is plastic pollution. But few people really realize just how much plastic is in the waters – a new study estimates that there are at least 5.25 trillion pieces which weigh an estimated 269,000 tonnes. The real number however may be even much larger than that. Plastic
The ocean abyss hasn’t warmed significantly since 2005, according to a new NASA study, further deepening the mystery of why global warming has apparently ground to halt in the past couple of years. The researchers stress, however, that the findings do not indicate that there isn’t any man-made climate change; sea levels are still rising, it’s just the fine details that
Giant whirlpools or mesoscale eddies, as described in scientific literature, can grow between 100 km and 500 km in diameter, forming around islands where ocean currents become disrupted. These whirlpools carry immense amounts of water and heat, but up until now they’ve been largely ignored in climate models. A novel research, however, found that energy dispersed by the giant eddies shouldn’t
As if that would be our biggest concern in the first place, but it’s important to understand, especially for policy makers, that even though dumping CO2 as a byproduct of current energy production methods is a lot cheaper than “cleaner alternatives”, in the long run the balance of economics turn. A new report released today at the Third Symposium on
Images from NASA’s Cassini spacecraft have enabled scientists for the first time to create a correlation between spraying of jets of water vapor from fissures on Saturn’s moon Enceladus with Saturn’s gravity and the way it creates stress on the fissure. “This new work gives scientists insight into the mechanics of these picturesque jets at Enceladus and shows that Saturn
Oceana is the ocean conservation organization, and they’ve been doing a series of infographics which I found absolutely fantastic! So I’d like to share them with you, in the hope that you will too, as well as learn something. Infographic: Where Does Our Seafood Come From? Link Eighty-four percent of seafood eaten in the U.S. is imported, and it follows
Bacteria and small plants at the bottom of the ocean require significant quantities of iron to survive and grow, just like us humans do. But their situation is extremely different, and they can’t just opt for an iron rich diet. So where does their iron come from ? Pyrite, or fool’s gold (as it is sometimes called) is a
Mark Benfield from Louisiana State University, Baton Rouge was undertaking a survey when he spotted this amazing oarfish at about 10 meters long. The fish is one of the longest in the world, and it’s general aspect resembles that of a serpent, so it’s possible it lies at the basis of some sea serpent myths. Professor Benfield explains how they
I was surprised to talk to a bunch of people today and find out they didn’t know about this, so I figured this is definitely something worth knowing. Here’s the deal. There’s a whole lot of garbage floating around; a whole lot ! Some are above the surface, some are below. What happens is they get sucked in by oceanic
Every year, around this time of year, more than 100 million determined crabs take to the streets in a massive attempt to get to their spawning grounds as soon as possible; as a result, they literally flood the streets in Christmas island, covering the streets and forcing rangers to divert traffic and use some quite creative methods of protecting the
Blue whales are not only the biggest living creatures in the world right now, but the biggest ever to have ‘walked’ the face of the earth; they’re also the loudest for that matter. After recovering from near extinction in the beginning of the 20th century, blue whales are finally getting a part of the respect they deserve. However, researchers cannot
According to the Australian Antarctic Division, at least a hundred Antarctic icebergs are currently drifting towards New Zealand at a speed that alarmed local authorities as well as specialists from all over the world. A glaciologist from inside the organization said that they already passed the Auckland islands and are currently heading for the main South Island; these icebergs are
