In pitch dark at 40 below, a research expedition set out to the icy Arctic Ocean in January 2015.Their goal: to better understand ongoing changes in the Arctic due to a shift from an older and thicker ice cover that would survive the summer melt to a younger and thinner one that, to a larger degree, melts away in the summer.
Research activities focusing on high-impact weather – from basic research in the academic community to operational contributions.

Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area. These strong winds lift large amounts of sand and dust from bare, dry soils into the atmosphere, transporting them hundreds to thousands of kilometres away. Some 40% of aerosols in the troposphere (the lowest layer of Earth’s atmosphere) are dust particles from wind erosion.

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.
