A legitimately spooky crack on an Antarctic ice-skating rink sheet that was first discovered last Halloween is prompting a scientific inquiry station to cancel its 2018 winter field time of year .
Citing the “ tycoon and unpredictability of nature , ” British Antarctic Survey theater director Dame Jane Francisannounced todaythat the Halley VI Research Station will be closed from March to November 2018 to see to it the safety of its scientists . The BAS is touch on about the so - bid Halloween crevice , which has been migrating eastward across the Brunt Ice Shelf ever since it was discovered on October 31 , 2016 . The shot , which was just about 31 miles ( 50 kilometer ) long as of last hebdomad , consist just north of Halley VI and could threaten the constancy of the 150 - meter deep chalk shelf on which it sits .
Halley VI ’s wintry sward is also jeopardise by a chasm to the Confederate States , which , after 35 years of dormancy , has been speed up northward for the past seven months . Should either snap or chasm stimulate part of the sparkler ledge to snarl off into the ocean , the BAS would prefer nobody be around to witness it .
Today , the European Space Agency unblock a glorious novel image of the Brunt Ice Shelf , using data from the Copernicus Sentinel-1 satellite :
As Jane Francis explained in a program line , Halley VI ’s staff members can be whisked out of harm ’s room with relative ease in the summertime . But “ access to the station by ship or aircraft is passing hard during the winter month of 24 - minute darkness , super low temperatures and the frozen ocean . ”
It ’s the second year in a wrangle that wintertime research at Halley VI has been cancel out of an copiousness of caution . Last December , scientist were also thrust to tow the modular inquiry place 14 stat mi inland toensure it would n’t be on the “ wrong side of the crack”should a major calving event pass .
Halley VI is the in style in a retentive line of merchandise of British - persist research station that have canvas Earth ’s atmospheric state and space weather from atop East Antarctica ’s Brunt Ice Shelf . Earlier iterations of the station led to the discovery of the south-polar ozone hole in 1985 , whose recovery Halley scientists are currently tag .
Halley researchers also participate in European Space Agency - lead studies to understand how world will conform to the long turn of darkness and isolation characteristic of both Antarctica and outer space .
grant to the British Antarctic Survey , recent change to the Brunt Ice Shelf are driven by the innate cognitive process of shabu flowing out to sea . Eventually , a buildup of stress causes ice shelfs to break off into iceberg lettuce .
In other part of Antarctica , accelerated Methedrine shelf separation is being driven by rising temperatures . Natural calving issue allow scientist to study how this frozen continent , whose shelves concord back many foot of possible sea storey rise , will vary as we continue to warm the major planet .
Athena Dinar , a interpreter for the BAS , told Earther that scientists are starting to guide down for the summertime 2017 - 2018 field of study season . She added that any iceberg calving issue “ is unlikely to happen quickly , ” and that the BAS is monitoring the situation on the Brunt Ice Shelf close with radar and satellites .
