The onset of the summer melt season in spring is an important aspect of the seasonal cycle in the Arctic Ocean, yet the processes that contribute to it are poorly understood at least in part because of a lack of detailed observations during this time of the year. The hypothesis in the ARTofMELT project is that the onset is triggered by anomalies in the surface energy budget due to intrusions of warm and moist mid-latitude air in combinations with several feedback mechanisms involving clouds and radiation coupling directly to surface and upper ocean warming. To help improve this situation, the Swedish icebreaker Oden will be deployed in the Atlantic sector of the Arctic sea ice and navigated to locations where such intrusions are expected using ensemble weather forecasting. When the warm-and-moist air arrives, detailed observations during the event will be possible from the icebreakler, in the column fromn the upper ocean through the ice and the troposphere. This proposal aims to support the participation of Early Career Scientists in the planning of the project, in order to facilitate participation in the project.
