Knowledge Gaps
Physical science / mechanism

- Where would this technique have the greatest impact? (e.g., Huss et al. 2021 found that covering 10 largest glaciers in Swiss Alps instead of 1000 allows achieving >1/3 of possible effect of 1000.)
Engineering needs (technical feasibility)
Version published:
March 31, 2025 - 9:01pm
- Where would this technique be logistically feasible? Areas need to be accessible with current deployment methods (Xie et al. 2023).
- Is there a plant-based or other natural material that would be effective? Can the material biodegrade? If yes, on what timescales?
- How can geotextile material be secured? Is there a possibility for application on moving glaciers and sea ice that does not destroy the geotextile?
- Can longer-lasting geotextiles be made?
Cost
Version published:
March 31, 2025 - 9:01pm
- Can costs be reduced? Currently this technique is very expensive.
Scalability
Version published:
March 31, 2025 - 9:01pm
- Is there a different deployment method that would make this technique scalable?
Environmental risks / benefits
Version published:
March 31, 2025 - 9:01pm
- Toxicity studies of chemicals and plastics weathered from geotextiles.
- Studies of application of cellulose acetate films to sea ice.
- How does a film- or geotextile-covered area of sea ice impact organisms that rely on sea ice?
Governance
Version published:
March 31, 2025 - 9:01pm
- There is need for an inclusive governance approach that incorporates stakeholder concerns in the design and deployment of approaches and effectively communicates risk (Bennett et al. 2022).
- 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)?
