Atmospheric isoprene measurements reveal larger-than-expected Southern Ocean emissions
Julia Schmale, Andrea Baccarini
Isoprene is a key trace component of the atmosphere emitted by vegetation and other organisms. It is highly reactive and can impact atmospheric composition and climate by affecting the greenhouse gases ozone and methane and secondary organic aerosol format ...
2024Characteristics and sources of fluorescent aerosols in the central Arctic Ocean
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Nora Bergner, Oliver Müller, Alireza Moallemi, Hélène Paule Angot, Markus Frey, Margarida Teles Nogueira Rolo
The Arctic is sensitive to cloud radiative forcing. Due to the limited number of aerosols present throughout much of the year, cloud formation is susceptible to the presence of cloud condensation nuclei and ice nucleating particles (INPs). Primary biologic ...
2024Untangling the influence of Antarctic and Southern Ocean life on clouds
Julia Schmale, Hélène Paule Angot, Jenny Thomas, Markus Frey
Polar environments are among the fastest changing regions on the planet. It is a crucial time to make significant improvements in our understanding of how ocean and ice biogeochemical processes are linked with the atmosphere. This is especially true over A ...
2023Polar oceans and sea ice in a changing climate
Julia Schmale, Hélène Paule Angot, Jenny Thomas
Polar oceans and sea ice cover 15% of the Earth’s ocean surface, and the environment is changing rapidly at both poles. Improving knowledge on the interactions between the atmospheric and oceanic realms in the polar regions, a Surface Ocean–Lower Atmospher ...
2023Host starvation and in hospite degradation of algal symbionts shape the heat stress response of the Cassiopea-Symbiodiniaceae symbiosis
Anders Meibom, Stéphane Laurent Escrig, Cristina Martin Olmos, Nils Rädecker, Guilhem Maurice Louis Banc-Prandi, Gaëlle Delphine Toullec
Global warming is causing large-scale disruption of cnidarian-Symbiodiniaceae symbioses fundamental to major marine ecosystems, such as coral reefs. However, the mechanisms by which heat stress perturbs these symbiotic partnerships remain poorly understood ...
2023Southward shift in the zero-degree isotherm latitude (ZIL) in the Antarctic Peninsula
The seasonal movement of the zero-degree isotherm across the Southern Ocean and Antarctic Peninsula drives major changes in the physical and biological processes around maritime Antarctica. These include spatial and temporal shifts in precipitation phase, ...
2023Highly Active Ice‐Nucleating Particles at the Summer North Pole
The amount of ice versus supercooled water in clouds is important for their radiative properties and role in climate feedbacks. Hence, knowledge of the concentration of ice-nucleating particles (INPs) is needed. Generally, the concentrations of INPs are fo ...
2022Key challenges for tropospheric chemistry in the Southern Hemisphere
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that particularly impact the Southern Hemisphere. In this article, we ...
2022Arctic atmospheric mercury: Sources and changes
Global anthropogenic and legacy mercury (Hg) emissions are the main sources of Arctic Hg contamination, primarily transported there via the atmosphere. This review summarizes the state of knowledge of the global anthropogenic sources of Hg emissions, and e ...
2022What are the likely changes in mercury concentration in the Arctic atmosphere and ocean under future emissions scenarios?
Arctic mercury (Hg) concentrations respond to changes in anthropogenic Hg emissions and environmental change. This manuscript, prepared for the 2021 Arctic Monitoring and Assessment Programme Mercury Assessment, explores the response of Arctic Ocean Hg con ...
