MOSAiC: Sea Salt Aerosol above Arctic Sea Ice – sources, processes and climate impacts (SSAASI-CLIM)

 Who are the people in the team?

Dr Markus Frey (PI), senior research scientist, (British Antarctic Survey)

Markus Frey, Principal Investigator

Dr Amelie Kirchgäßner (Co-Investigator), senior research scientist, (British Antarctic Survey)

Dr Thomas Lachlan-Cope (Co-Investigator), senior research scientist, (British Antarctic Survey)

Dr Xin Yang (Co-Investigator), senior research scientist, (British Antarctic Survey)

Dr Anna Jones (Co-Investigator), senior research scientist, (British Antarctic Survey)

Dr Leon Clarke (Co-Investigator), senior lecturer, (Ecology and Environment Research Centre, Manchester Metropolitan University)

All BAS scientists are part of the BAS science programme ‘Atmosphere, Ice and Climate’ with expertise in atmospheric & glaciochemistry (Frey, Jones), atmospheric physics with a focus on clouds and aerosol (Kirchgäßner, Lachlan-Cope) and global atmospheric chemistry modelling (Yang). Co-I Clarke is a biogeochemist with expertise in a wide range of environmental analytical trace chemistry techniques.

What are the questions asked in the framework of the MOSAiC project?

“… Atmospheric particles and their impact on clouds play a critical role in the current temperature increase and dramatic sea ice loss we observe in the Arctic region. However, in the remote central Arctic natural particle sources and processes related to sea ice are only poorly known. Thus, MOSAiC affords us an amazing opportunity to fill that knowledge gap and carry out experiments on the sea ice and in the air througout an entire year, and follow sea salt and other particles from their sea ice source at the surface all the way to the altitude where clouds form.”

When will the team be on the ship?

CoI Dr A Kirchgäßner participated on Leg1a to set up all the instrumentation for SSAASI-CLIM on board the RV Polarstern and on the ice flow.

PI Dr M Frey will be likely joining RV Polarstern during the winter/spring transition (leg3: Feb-Mar 2020).

How are you getting to the ship?

Likely via Russian icebreaker.

 What else have you worked on?

We have worked on chemical air-(sea)ice interactions and their impact on air quality, atmospheric particles and implications for clouds and climate. We also use newly gained process understanding to measure and interpret the chemical record preserved in polar ice cores.
