What might it count like if you " deplume the plug " in theMariana Trench — the planet ’s bass blot — and drained the water from all the oceans in the world ?
A late meter - reverting video portrays that speculative scenario using existent data , shown in an animation byRyan Brideau , a passe-partout prospect in geospatial visualization and analysis at the University of New Brunswick in Canada .
In this draining scenario, California surfers would have to travel a lot farther to catch those gnarly waves.
In the aliveness , posted to Reddityesterday ( Dec. 10 ) , a flat map of Earth reveals coastlines extend and land bridges appearing between continents and former island as the sea shrink . Meanwhile , islands and landed estate masses emerge from the oceans as the piddle drain by , over a period of almost 3 million years .

drain in the Pacific Ocean where the trench is locate continue to the end of the animation — which lasts about 30 endorsement — while other large torso of water quickly become landlocked and cease to drain at all , Brideau wrote on Reddit .
He explicate that he first encounter the idea of an imaginary whale " plug " in the deep part of the ocean — and what might happen if that plug were removed — in the leger " What If ? Serious Scientific Answers to Absurd Hypothetical Questions " ( Houghton Mifflin Harcourt , 2014 ) by Randall Munroe , the writer and illustrator behind the exquisitely nerdy ( and humorous ) science comicxkcd .
Munroe , who also drop a line about the intriguing enquiry ina blog post , envisioned a fire hydrant measuring about 33 feet ( 10 beat ) in diameter , with the water somehow fell at the drainage point and materializing on Mars ( in casing you were wonder where all that liquid would end up ) . He estimated in the Charles William Post that it would take hundreds of thousands of year for substantial drain to happen , withsea levelsdropping at " less than a centimetre a day , " he wrote .
Brideau was fascinate by the challenge of re - creating an animated variation of the modelling that Munroe used for that scenario , the researcher say Live Science in an email . He located a visualization of draining oceanscreated by NASA scientistsin 2008 , but those researchers ingest " a major shortcut " by not factor out in the connections between oceans , Brideau explained .
" That makes a grown conflict in terms of difficultness , and I wanted to see how close I could get to Randall ’s result myself , " Brideau said in the electronic mail .
create a visualization like this requires high - resolutionelevation mapsof land social system above and below sea level , along with location datum for all the major water bodies on Earth , Brideau explained .
" These call for to be in ' raster ' form , which is simply an image , but or else of each pixel transcription colour , they record raising or the presence / absence seizure of water , " he order .
The model then estimated drain in the oceans , adjusting for change inconnections between bodies of wateras they become obscure by emerge seafloor structures and give up to drain , Brideau explained .
" The hard part is calculate the remaining water at each looping , " he enunciate . " You have to reckon out which areas of water in the previous step were ' drainable ' and subtract them from the remaining water , but leave the water supply bodies that were untouched in place . You also have to subtract any landforms that have started sticking out of the water system .
" The big variable that I did n’t take into explanation is the weather , which might cause some water body to start to dry out if their primary source of incoming piddle is presently the ocean , " Brideau told Live Science .
" But in world , the weather would also be switch , so it ’s hard to predict , " he say .
His model figure dramatic changes to thecontinental coastlinesin the first 200,000 years . Toward the end of the animation — nearly 3 million years after the nag was pull out — only the Pacific Ocean is still run into the drainage jam in the trench . At this point , every systema skeletale in the animation represents a drop in ocean depths of about 33 foot ( 10 meter ) Brideau save on Reddit .
" I distinctly think as a kid my brother and I pulling on a roach at the beach that we were win over was connected to a giant plug at the bottom . It ’s just a fun thing to mean about , " Brideau said .
