According to researchers from the US National Center for Atmospheric Research, the ice that covers the Arctic Ocean could completely dissolve during the summer months by the year 2040. The北极对气候变化的高敏感性使它成为一个理想的testing ground for climate trends, and the data acquired on this region plays a major role in our understanding of the earth’s climate.

In the context of its philanthropic effort to promote scientific research aimed at preserving the earth’s atmosphere,空气液化基金会支持两次探险whose shared aim is to gather important data related to climate change for subsequent use by the global scientific community.

这“Generali Arctic Observer” expedition conducted by French physician and explorer Jean-Louis Étienne将首次在北极上方的大气组合上进行测量。Jean-Louisétienne将在氦气气球中遍历北冰洋2010年4月，为期两周。在此次探险期间，他将进行两项同时的科学测量运动：第一个将涉及测量缺乏这种排放的地区的大气中的二氧化碳水平和气溶胶。收集的数据将用于提高我们对行星碳循环的理解，并改善设计的模型，以衡量气候趋势。第二个活动将涉及地球磁场的测量。空气液化基础是通过提供填充气球所需的氦气以及允许探险家在他旅行的高海拔阶段呼吸的氧气来支持这一探险。

这thickness of the polar ice caps, unlike their surface, has not received much scientific attention to date. As ofMarch 2010，这“在杆下”探险队将负责测量of the thickness of the ice over a distance of 800 km of ice cap, extending from the North Pole to the furthest reaches of Northern Canada. This expedition, composed of eight explorers, will gathernever-before collected databy combiningdiving underneath the ice cap and taking surface measurements. These field measurements will allow researchers to optimize and increase the precision of existing evaluations of the volume of the ice cap. The four-month research program, supported by the Air Liquide Foundation, is part of a broader European program of Arctic climate observation and modeling.
