Scientists have found evidence of an "ancient buried landscape" that was once above North Atlantic waters, the temporary result--at least in geographical terms--of thermal turmoil beneath the planet's surface.
In "Transient convective uplift of an ancient buried landscape," Ross A. Hartley and his co-authors write that pressure forced parts of the European continental shelf above water in three discrete steps of up to 400m.
Here, we use three-dimensional seismic data to reconstruct one of these ancient landscapes that formed off the northwest coast of Europe during the Palaeocene-Eocene Thermal Maximum. We identify a drainage network within the landscape and, by modelling the profiles of individual rivers within this network, we reconstruct the history of surface uplift. We show that the landscape was lifted above sea level in a series of three discrete steps of 200-400â€‰m each. After about 1 million years of subaerial exposure, this landscape was reburied
P.S. This new Atlantis' time in the sun was a good 55m years ago, which means we can just go totally science fiction with it.

The Bank of England has unveiled its new £50 notes, which had been earmarked to honour a distinguished British scientist, and which will feature Alan Turing, the WWII hero who discovered many of the foundational insights to both modern computing and cryptography, and whose work with the codebreakers of Bletchley Park are widely believed to […]
The great science purge, they’ll call it one day. Donald Trump is closing science offices throughout the federal government. ‘As of June, around 85 percent of all scientific posts in the federal government, including an official scientific advisor to the President, were left unfilled,’ write the editors of I F***ing Love Science blog in an […]
Ed Hawkins, a climate scientist, created Show Your Stripes as a way to easily visualize the past century's climate change: give it a location and it will render a series of stripes representing a century's worth of average annual temperatures (above: global average temperature); as Kottke notes: "The warming patterns for particular regions are not […]
When it comes to passwords, there’s no such thing as paranoia. You want them secure and complex, and you definitely don’t want to repeat them on all your accounts. The trouble is, the internet seems to keep growing. And so do those accounts. Just one lockout from an important email or banking site is enough […]
With the rising temperatures on tap this summer, the climate is going to be a frequent topic of conversation, and those conversations won’t be happy ones. Luckily, there’s a way to do a little climate change of your own – in a safe and sustainable way. When it comes to personal air conditioners, EvaPolar is […]
Whether you’re using them for next-level selfies or steady tracking shots, gimbals are a must for anyone who wants to maximize the potential of these powerful smartphone cameras we’re all carrying around. But those smartphones are also supposed to be portable, and let’s face it: Gimbals tend to offset that advantage. Weighing in at just […]
