Later this workweek , an Antarctic expedition will set off to map the submarine currents that play a critical role in modulate our major planet ’s clime . To assist them , the scientists will utilise an independent submarine that was famously list Boaty McBoatface by the corporate genius of the internet .

The project , called the DynOPO ( Dynamics of the Orkney Passage Outflow ) expedition , is a joint effort between the British Antarctic Survey ( BAS ) and Southampton University . By mapping the flow of Antarctic Bottom Water ( AABW ) within the 11,500 - foot ( 3,500 meter ) mysterious Orkney Passage , the researchers are hoping to understand how these significant abstruse sea electric current are being affected by climate variety .
To assist them , the investigator will be equipped with Boaty McBoatface , the first of three long - range autonomous submarines that are being developed by the National Oceanography Center ( NOC ) . The sobriquet comes from last yr ’s effort by the Natural Environment Research Council to name the UK ’s new opposite inquiry ship . In a now - notorious event , the public vote for Boaty McBoatface , butthe humorless British government deemed it unsuitable , pick out the much more boring name of Sir David Attenborough instead .
As consolation , and to keep the name alive , a hero sandwich was dubbed Boaty instead .

Along with Boaty , the scientist will digress Punta Arenas in Chile on March 17 aboard the BAS research ship RRS James Clark Ross . They will lead to an area of the Southern Ocean about 500 air mile from the Antarctic Peninsula , from which they ’ll deploy an array of instrument , including some that will be moored to the seafloor . These tools , along with the sub , will measure ocean turbulency at capital depths .
Boaty will travel back and forth along an abyssal stream of AABW through the so - called Orkney Passage . It ’ll measure the chroma of the menses , which acts as a kind of submarine conveyor rap , bring frigid urine to the Earth ’s equatorial regions , and contribute to global circulation . At the Orkney Passage , this deepsea flow goes through a “ bottleneck ” as it heads from Antarctica ’s Weddell Sea to the Atlantic Ocean .
Recently , scientists have suspected that changing winds over the Southern Ocean are affect the speed of seafloor current carry AABW — and that could be affect the amount of riotous current in the Orkney Passage .
“ We know that a major driver of the abyssal sea thawing , at least in the Atlantic Ocean , is change in farting over the Southern Ocean , ” note hint scientist Alberto Naveira Garabato from the University of Southampton in a statement . “ The abyssal water of the World Ocean sump in the Southern Ocean , and course northward along the seafloor in submarine current . When these stream encounter submarine topography or key chokepoints , they voyage it by mash through vale and around mountains , occasionally forming grinder falls — much as a river flowing toward the sea does on the Earth ’s surface . ”
Today , scientists distrust that more passion is getting fuse into AABW from shallower , warmer sea layers . This warmer water is getting birth to the equator , and it could be bear upon the planet ’s climate . The Orkney Passage is likely a cardinal chokepoint in this process , which is why the researchers are desire to learn more about the speed of its current , the degree of upheaval down below , and how deep sea water are responding to modification in the winds over the Southern Ocean . at last , the researchers would care to create models to help them forebode how our climate will exchange during the twenty-first C and beyond .
“ One of the most surprising feature of the climate change that we are currently get is that the abyssal waters of the world ocean have been warming steady over the last few X , ” said Garabato . “ found the causal agent of this warming is crucial because the thawing plays an crucial role in moderating the ongoing — and likely future — increases in atmospheric temperature and sea stratum around the globe . ”
Boaty McBoatface may have a silly name , but its mission is far from trivial . If nothing else , its name will belike take out supererogatory tending to the projection , and school the public about the ongoing upshot of climate alteration .
