The BBVA Foundation Frontiers of Knowledge Award in Climate Change has gone in this sixteenth edition to Jakob Schwander along with Dorthe Dahl-Jensen, Jean Jouzel, Valérie Masson-Delmotte and Thomas Stocker "for contributions to the polar ice core records that establish a fundamental coupling between greenhouse gases and air temperature characterizing climate change over the past 800,000 years".
Jakob Schwander declares himself “passionate” about engineering and ice drilling techniques. And the Swiss scientist has been a great innovator on this side of his field developing, improving and creating new devices to reach ever deeper layers of pristine ice. This, precisely, has been one of his major contributions. Thanks to his inventions, Schwander was able to study the air bubbles trapped in the “firn”, the layer of compacted snow above the glacial ice that endures winter after winter at depths of more than 70 meters, where 25% of air is concentrated. In 1984 he published a paper in Nature which concluded that the age of this trapped air was considerably younger than that of the enclosing ice. His research has made it possible to more accurately determine ice core ages at different depths, enabling more precise records to be constructed of past temperatures and rainfall. Around ten years ago, Schwander turned his attention to developing what would become his signature invention, the smallest ice drill in the world. The RADIX (Rapid Access Drill for Ice eXtraction), has a diameter of just 2 cm, enabling it to reach depths of 320 meters (-55oC) in the Antarctic ice in just a few days’ work.
