Aerosol source identification in the spring and summertime central Arctic Ocean using high-resolution mass spectrometry during MOSAiC.

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Imad El Haddad, Jakob Boyd Pernov, Hélène Paule Angot, Lubna Dada

The Arctic region is undergoing considerable changes and is warming at a rate three to four times as fast as the rest of the world. Aerosols, which can originate from natural or anthropogenic sources, both of which can be locally emitted or long-range tran ...

A full year of aerosol size distribution data from the central Arctic under an extreme positive Arctic Oscillation: insights from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Hélène Paule Angot, Lubna Dada, Federico Bianchi

The Arctic environment is rapidly changing due to accelerated warming in the region. The warming trend is driving a decline in sea ice extent, which thereby enhances feedback loops in the surface energy budget in the Arctic. Arctic aerosols play an importa ...

Identification of human milk oligosaccharide positional isomers by combining IMS-CID-IMS and cryogenic IR spectroscopy

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Ali H Abikhodr, Vasyl Yatsyna

High-resolution ion mobility spectrometry (IMS) coupled with cryogenic infrared spectroscopy has proven to be a powerful technique for the identification of oligosaccharides. However, the need for an extensive database, combined with the scarcity of pure s ...

The Marginal Ice Zone as a dominant source region of atmospheric mercury during central Arctic summertime

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot

Atmospheric gaseous elemental mercury (GEM) concentrations in the Arctic exhibit a clear summertime maximum, while the origin of this peak is still a matter of debate in the community. Based on summertime observations during the Multidisciplinary drifting ...

Annual aerosol chemical composition retrieved from an aerosol mass spectrometer in the central Arctic

Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Hélène Paule Angot, Lubna Dada

The Arctic environment is transforming rapidly due to climate change, which induces several feedback processes such as retreating sea ice, changing atmospheric transport patterns and cloud formation. In addition, more local pollution due to shipping and re ...

Surface Analysis by Secondary Ion Mass Spectrometry (SIMS): Principles and Applications from Swiss Laboratories

Anders Meibom, Stéphane Laurent Escrig, Florent Olivier Vivien Plane, Lukas Baumgartner, Thomas Bovay

Secondary Ion Mass Spectrometry (SIMS) extracts chemical, elemental, or isotopic information about a localized area of a solid target by performing mass spectrometry on secondary ions sputtered from its surface by the impact of a beam of charged particles. ...

Observing the Central Arctic Atmosphere and Surface with University of Colorado uncrewed aircraft systems

Julia Schmale, Radiance Flore Aurore Calmer

Over a five-month time window between March and July 2020, scientists deployed two small uncrewed aircraft systems (sUAS) to the central Arctic Ocean as part of legs three and four of the MOSAiC expedition. These sUAS were flown to measure the thermodynami ...

Chemical and Microphysical State of the Central Arctic Atmosphere

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada

The Arctic is warming three times faster than the rest of the planet. Increased areas of open ocean and changes in atmospheric transport pathways affect the Arctic atmospheric chemical and microphysical state, which themselves can modulate cloud, precipita ...

Unravelling the structures of sodiated beta-cyclodextrin and its fragments

Thomas Rizzo, Robert Paul Pellegrinelli, Eduardo Carrascosa Casado, Ali H Abikhodr

We present cryogenic infrared spectra of sodiated beta-cyclodextrin beta-CD + Na, a common cyclic oligosaccharide, and its main dissociation products upon collision-induced dissociation (CID). We characterize the parent ions using high-resolution ion ...
