The main goal of the final scientific workshop of the ARKTALAS Hoavva project was to assess the state of the art in use satellite measurements in synergy with in-situ data and modelling tools to characterize and quantify the processes driving changes in the Artic sea ice and Arctic Ocean. This was in particular tailored to the following major interlinked and cross-disciplinary Arctic Scientific Challenges (ASC) addressed in the Arktalas Hoavva project:
- ASC-1: Characterize Arctic Amplification and its impact
- ASC-2: Characterize the impact of more persistent and larger area of open water on sea ice dynamics
- ASC-3: Understand, characterize and predict the impact of extreme event storms in sea-ice formation
- ASC-4: Understand, characterize and predict the Arctic ocean spin-up.
In so doing the status of the published and submitted scientific papers to international peer review journals (see list below) under this Arktalas Hoavva project were presented and assessed in respect to achievements and findings relevant to the four ASC. Moreover
