Physical science / mechanism

- How does blocking sea ice export from targeted areas impact the growth of new ice?
- How would blocking sea ice export influence atmospheric temperature and circulation?
- How would blocking sea ice export influence ocean circulation?
Engineering needs (technical feasibility)
Version published:
July 17, 2026 - 12:55am
- What device would be effective in blocking sea ice export and be minimally invasive to Arctic organisms?
- How does an artificial structure blocking sea ice export impact turbulence?
- Design cable / structure to block ice export (particularly difficult given extremely high currents, winds, and ice pressures in Nares Strait).
- Identify/design mooring or structure that would secure the cable or blocking structure (note that Nares Strait would be a particularly difficult place to deploy and maintain a mooring due to extremely high currents, wind, and ice pressures).
Environmental risks / benefits

- What are the downstream effects of an artificial structure blocking sea ice export in terms of turbulence and biogeochemistry?
- What are the implications of ice thickening approaches, including changes in stratification and nutrient transport?
- Build on previous work (Bergeron and Tremblay 2014, Ren et al. 2022, Moore et al. 2023) to determine potential impacts (positive and negative) of blocking sea ice export on the Sarvarjuaq / Pikialasorsuaq polynya.
- Zeitler and Brunell (2024) began adapting a Performance Assessment methodology as an initial risk assessment framework for Arctic climate interventions, beginning with a focus on factors associated with the atmosphere. The methodology should be completed for a full risk assessment (Zeitler and Brunell 2024) and can be adapted more specifically to individual approaches.

Governance

- Can Indigenous rights and perspectives be incorporated in governance of ocean-based climate solutions when solutions are implemented in the name of global environmental protection (Chuffart et al. 2023)?
- Chitty et al. (2025) lists key questions that need to be answered to advance just and equitable governance strategies for climate interventions in the Arctic.
