That rock you see above? It's 620 tons, over 2.5 times the weight of the Statue of Liberty.
Yet some powerful wave in the North Atlantic was mighty enough to lift it out of the sea and plop it onto land.
Everyday ocean waves are way more powerful than we ever thought: This is the conclusion of a fascinating paper by geoscientist Ronadh Cox and her research group. Scientists long knew there were unusually huge rocks hurled ashore around the world, but generally they assumed they'd been tossed up by tsunamis, rare tectonic events.
Nope. It looks like regular 'ol storm-waves can manage these sorts of feats. Cox and her group took a bunch of before-and-after photos of the northwest coast of Ireland around the time of a 2013-2014 storm cluster, and identified several boulders that the storms had thrown ashore. They were huuuuuuuge!
No wonder Homer called Poseidon the "earth-shaker".
The paper is here online in full, and is both layperson-parsable and seriously gripping.
Given that global warming is pouring evermore energy into the oceans, we're going to need to reassess just how powerful coastal waves can get, as Cox points out in this story about her work:
“Why bother with this study?” Cox knew members of the audience might be asking. If these deposits are formed by storms, then we can better understand storm dynamics and coastal processes. This information will be important as global climate changes cause storms to become more frequent and intense. The research could also help to constrain tsunami models elsewhere. “But from my perspective, it’s just cool. It’s just fun,” added Cox.
I’ve mentioned it online before, but here we go: Two years ago, my wife and I decided to leave our rented home behind and move into a 40-foot RV. We spend our spring and summer in Alberta, Canada where she has a job for six months of the year working as an addictions counselor. The […]
Androkavo tests some of the cheap eBay solder against the brand-name stuff; it gets there in the end, but it’s surely not the advertized 60/40 alloy and needs to be close to 400° before it behaves itself.
MIT Tech Review's Antonio Regalado rounds up the year's stupidest, worst moments in tech, from the guy who created his own CRISPR-based gene therapy to beef up his muscles and injected it to Donald Trump's Twitter feed to the FCC's Net Neutrality catastrophe. Of course, Juicero rates a mention.
Our world is a colorful one, and when it comes time to repaint the house or create a new design, many of us look to our surroundings for inspiration. However, matching colors from the outside world to our canvas isn’t the most precise process when we’re just eyeballing it. The Nix Pro Color Sensor removes the […]
You probably remember the Twisty Glass Blunt since we love to write about it. And you may also remember its little buddy, the Twisty Glass Mini. Well, today we’ve got a fun surprise that isn’t so little. Less isn’t always more, and on those days when you need to decompress with a good smoke, the Twisty XL […]
Another year, another iteration of Samsung’s Galaxy smartphone—except this time around Samsung sought to redefine what a smartphone can do completely. Boasting a 6.2″ Quad HD+ Super AMOLED (2960×1440) infinity display, and an elite 10nm 64-bit Octa-Core Processor with 6GB RAM, the S9+ is an absolute powerhouse with a price tag to match. However, you […]
