Tracking down microplastics in Antarctica

Microplastics are everywhere, even in the most remote places. Where do these tiny pieces of plastic come from?

01-Dec-2021

Microplastics are an environmental problem since organisms ingest these tiny particles and can be harmed by them. Even remote regions such as Antarctica are affected. To quantify this form of pollution and find out where the small particles come from, a research team from the Department of ...

Climate Change makes Arctic Ozone Loss Worse

The expected recovery of the ozone layer may fail to happen anytime soon, if global warming is not slowed down

25-Jun-2021

In spring 2020, the MOSAiC expedition documented an unparalleled loss of ozone in the Arctic stratosphere. As an evaluation of meteorological data and model-based simulations by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) now indicates, ozone depletion in ...

Microplastic drifting down with the snow

In the Alps and the Arctic, experts confirm the presence of plastic in snow

16-Aug-2019

Over the past several years, microplastic particles have repeatedly been detected in seawater, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow – and even in such remote regions as the ...

Methane measurements at low level flight

31-Jul-2012

A team of scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) and the GFZ German Research Centre for Geosciences has just completed an airborne measurement campaign that allowed for the first time to measure large-scale methane emissions ...

Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns

Still too much uncertainty in today's climate models

11-Mar-2008

Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere. This is the result of climate simulations, which have just been published in the journal "Geophysical Research Letters" (Brand et ...
