Climate researcher just lost part of an important collection of ancient Arctic methamphetamine hydrochloride effect , after a deep freezer malfunction sent heat , instead of cold , circulating around the samples .
The University of Alberta in Edmonton confirmed last week that the freezer failure resulted in a fond melting ofice core samplesfrom the Canadian Ice Core Archive ( CICA ) , touch 12.8 percent of the collection . The CICA is the reality ’s large ingathering of Canadian Arctic ice core samples , with more than 80,000 years of climate data in what amount to 0.87 miles ( 1.4 kilometre ) of ice .
A freezer malfunction damaged about 13 percent of the Canadian Ice Core Archive, a collection of ice core camples with more than 80,000 years of climate data.
Ice marrow sampling can act as clip machines because the samples contain such thing as strain bubbles , dust grains and pollen , offering scientists of import data aboutEarth ’s preceding climate , let in clues about temperature and the penning of the major planet ’s atmosphere .

" When you drop off part of an ice core , you lose part of the record of past climates , preceding environments — an archive of the chronicle of our atmosphere , " glaciologist Martin Sharp , lead researcher for CICA , said in a argument . " You just do n’t have easy access to information about those retiring time periods . "
The loss of the liquid nub datum is not the only impact on future enquiry , agree to Sharp . run water from one core segment can " contaminate " other segments , which , Sharp say , makes it difficult to analyze polluted segment . New technologies , such ascryogeniclasers , may be used to explore whether info can be salvaged from the partially melted sampling , he add .
Though the meat are stored in 3.28 - foot ( 1 metre ) segments , and no essence was completely lose in the Deepfreeze meltdown , the loss will still regard scientist ' sketch of the archive .
" This incident will bear on inquiry , no question . It reign out certain studies that we might have need to conduct on the cores , such as reconstructing continuous long - term history where part of the cores have been lost or foul , " Sharp enunciate . " We may have to reconsider some of the work we planned to do , but the piece of work can and will continue — and most 90 percent of the archive is still intact . "
According to the university , the integral CICA collection ( including the damaged samples ) has been moved to a different Deepfreeze and additional safeguard have been put in plaza .
