A group of New Zealand scientists carried out some exploding experiments on the Priestley Glacier in Antarctica to determine how the ice boards respond to temperature and other changes.
Professor David Prior of Otago University led a team that collaborated with Korean researchers at this Antarctic station.
In the Priestley Glacier, holes were drilled and filled with explosives that created sound waves at the time of opening, with which scientists better understood what controls the speed of ice.
Professor Prior said that field measurements were the same as those from laboratory experiments, which was a positive result, as laboratory work had to be done faster than the natural deformation process of the glacier.
"This is a real problem because if [we] It is [the laboratory experiments] for the same speed as nature would take 30 to 100 years.
"The first indication that the alignment of crystals in the natural system is the same as in experiments … is a good indicator that we can use the results of laboratory experiments to help us understand the flow of ice."
Professor Prior said that the "explosive" work carried out by his crew on the Priestley Glacier would eventually allow for a more accurate assessment of the short-term effects of the fall of the ice shelf.
He said that it is known that global warming would cause the ice layer to rapidly deflect, which would lead to an increase in the sea level by about half a meter in the next century.
"It is less clear what is a five-, ten- or twenty-year time frame, which is more important from a direct perspective of planning.
"The work we do will allow us to create models that, hopefully, will be more robust and will enable us [examine] shorter timeframes and effects. "
Work by prof. The priorities of the team and their Korean counterparts are for the first time that this type of seismological research is carried out in the area of glacier cutting.
