Tracking water vapor over Greenland's ice sheet with a drone

Julia Hager

A drone experiment over the Greenland ice sheet has made it possible for the first time to take detailed measurements of water vapor in the atmosphere over Greenland. This new technology could contribute to improving climate models and help to better estimate Greenland's future contribution to global sea level rise.

Forel, a Swiss research vessel for the scientists

Mirjana Binggeli

From mapping fjords to studying particles, the Forel research vessel leads multidisciplinary expeditions in the Arctic to better understand the impact of global warming and marine ecosystems. A true floating laboratory that looks like a Swiss Army knife.

Pleistocene glacial ice discovered in the permafrost of the Canadian Arctic

Julia Hager

On Bylot Island in the Canadian Arctic, bodies of ice have been hidden in the permafrost since the early Pleistocene – well protected from external influences and several warm periods. The age of the ice is estimated to be more than 770,000 years.

Study tracks male Sperm whales over thousands of kilometers

Julia Hager

Male sperm whales in the North Atlantic spend much of the year in Arctic waters, migrating south only for mating. For the first time, a research team has demonstrated that these migrations do not follow a fixed schedule.

Whales – the gardeners of the oceans

Julia Hager

Whales are considered the ecosystem engineers of the oceans. They stimulate the growth of phytoplankton, which in turn supports the growth of their primary food source, krill.

Does the carbon cycle in the Southern Ocean work differently than we thought?

Julia Hager

Diatoms, a key player in the Southern Ocean food web, may contribute less to the biological carbon pump than previously thought.

Significantly fewer pressure ridges in the Arctic sea ice

Julia Hager

The sea ice cover of the Arctic Ocean has not only shrunk and thinned due to global warming but has also become significantly flatter over the past three decades.

Krill play a key role in carbon storage – plastic disrupts this process

Julia Hager

Plastic pollution in the Southern Ocean may hinder the efficient transport of carbon bound by Antarctic krill to the deep ocean, with implications for the global carbon cycle and thus for global warming.

Marie-Noëlle Rimaud, islander, polar explorer and pioneer

Camille Lin

Polar tourism in Greenland is not a subject frequently addressed in French economic and social sciences. Yet Marie-Noëlle Rimaud is now able to capture what was once just over the horizon, and observe it through her own unique lens.

The Arctic is getting more light pollution due to increasing industrial activities

Julia Hager

The area affected by oil and gas production and mining in the Arctic is growing every year, as a new study by the University of Zurich shows. In addition to night-time light pollution, industrial activities lead to numerous other problems for nature and the environment.
