Art meets science – Unique photo exhibition provides glimpse into life during international research expedition SWERUS-C3

On an unseasonably warm Friday afternoon, on 3 October 2014, the Swedish icebreaker Oden returned to Tromsø, northern Norway, after 90 days cruising the cold waters of the East Siberian Arctic Ocean. The massive 100-meter-long, blue-yellow-red vessel glistened in the October sun, as it zipped through the fjord, towering over passing boats, to eventually drop anchor just two kilometres from …

Rainstorms make new clouds in the tropics

In the skies above the Amazon, large numbers of small air particles called aerosols that form naturally in the upper atmosphere are carried to the lowermost part of it, known as the boundary layer, by rapid downdrafts associated with rain convective clouds. This shows a new study by scientists from USA, Brazil, Sweden, Germany and Finland published in Nature. These findings shed …

China’s emissions of toxic fluorinated chemicals highest in the world

China is the biggest emitter of certain toxic fluorinated chemicals today, shows a new study published in Environmental Science and Technology. Researchers from Sweden, Norway and China have measured the levels of 12 fluorinated substances at the mouths of 19 Chinese rivers. “Our field measurements have confirmed the theoretical calculations of emissions”, says Thanh Wang, researcher at Örebro University who …

Abstract submission is open! – 6th Young Environmental Scientist Meeting

In collaboration with the student association of the Society of Environmental Toxicology and Chemistry (SETAC) we are happy to announce that ACES will be hosting the 6th edition of the Young Environmental Scientists meeting (YES) taking place from the 16th to the 20th of February. This will be the first time that the meeting is held in Scandinavia and roughly 100 students are …

World premiere of documentary film about SWERUS-C3

The world premier of a documentary film about the international research expedition SWERUS-C3 will take place on 11 October at Aula Magna, Stockholm University. The film takes the viewer on a journey through the preparatory work and planning to the life omboard and the process of collecting the data, and reveals some groundbreaking discoveries. Nina Kirchner, Associate Professor and Scientific Director at …

Origins of European Arctic soot revealed

The chemical make-up of soot passing through northern Sweden on the way to the European Arctic reveals fossil fuel combustion in the continent as the main source of soot in the winter, and forest fires in Russia as the main source in the summer. This is shown in a new study published in Nature Communications. For a little more than …

Stockholm University ranks among top 30 in the world in environmental studies

Stockholm University was ranked 28th in the world in environmental studies, according to QS World University Rankings by Subject 2016, published on 7 September. “The high ranking is a reflection of the excellent work being done by many faculty, students and staff within our faculty. I find it particularly encouraging in view of our efforts to create a strong research and …

ACES professor receives prestigious award

Professor Margareta Törnqvist received the Fritz Sobels Award for her lifetime accomplishment in the field of environmental mutagenesis during the 45th Annual meeting of the European Environmental Mutagenesis and Genomics Society (EEMGS) in Copenhagen, Denmark. Margareta Törnqvist’s work has focused on the development of advanced analytical methods, based on mass spectrometry, for the analysis of genotoxic compounds that form adducts …

New study reveals the origin of soot emissions that melt Himalayan glaciers

Northern India, China as well as nearby countryside were shown to be the origins of black soot that is largely responsible for the melting of glaciers in the Himalayan mountains of Tibet in a new study published in Nature Communications. Researchers from ACES and colleagues from the Chinese Academy of Sciences were able to determine not only the production sources of the …

Remembering Prof. Jón Egill Kristjánsson

It is with great sadness that we learned of the passing of Professor Jón Egill Kristjánsson, University of Oslo, who was killed in a climbing accident in the Norwegian mountains. Jón Egill was a very active, talented and internationally respected researcher and a good friend to many researchers here at ACES as well as the Bolin Centre for Climate Research. …

Thin tropical clouds cool the climate

Thin clouds at about 5 km altitude are more ubiquitous in the tropics than previously thought and they have a substantial cooling effect on climate. This is shown in a recent study by researchers from ACES and colleagues from Stockholm University and the University of Miami, which was published in Nature Communications. Mid-level clouds are currently missing in global climate models.  …
