Project Report

As Arctic warming increases, it is becoming increasingly important to understand the complex interactions between sea ice, surface water, snow cover and atmospheric aerosols. During the 2019/2020 period, extensive measurements took place in the Arctic, including the large-scale MOSAiC campaign and measurements on Svalbard, with the aim of understanding these processes as well as others. The Svalbard-MOSAiC workshop brought together researchers with diverse expertise and from different projects across the Arctic, in order to foster collaborations and networking in the topic of snow, sea-ice and aerosol interactions. The workshop was based around small-group discussions, each with a specific topic focus. The three key topics discussed included the deposition of aerosol onto snow and sea ice, the production of marine biogenic aerosols and the impact of aerosols on the radiation budget. Sixty-two attendees from 22 different groups attended the workshop, with 76% participating in focus group discussions.

Take-home messages focused around how to improve collaborations between groups, projects and researchers on a long-term, pan-Arctic basis. Conclusions included:

  • Sharing information between different research groups, disciplines and topics is incredibly important in understanding the interactions between different systems in the Arctic.
  • It is important for researchers to be aware of different projects taking place in the Arctic and datasets/potential collaborations that may be available. Ways to do this could include building an online system to log current Arctic research, or ensuring that topic-based workshops open to researchers on different projects take place and are well advertised.
  • The best way to share information and expertise can vary depending on the topic of study. For example, when studying the deposition of aerosols onto snow, large-scale sampling in a single location, with extended analysis and characterisation, can be extremely beneficial in increasing understanding. When researching marine biogenic aerosols, it was generally felt that bringing together information and data from different parts of the Arctic would be more valuable.
