- Most research has been done on local impacts as opposed to global impacts of ice thickening (van Dijke 2022); could there be a global effect – studies show mixed results?
- Explore effects of snow conditions on ice thickening and decay (van Dijke 2022).
- Further research on salt dynamics during freezing and flooding of snow cover and how this impacts reflectivity and mechanical behavior of ice (Zampieri and Goessling 2019).
- What causes the whiter ice from thickening?
- Does whiter ice from thickening maintain its high albedo over time? What is the albedo of thickened ice?
- What is the thermal conductivity of frozen slush and thickened ice? How do changes in thermal conductivity impact brine rejection and convection in underlying water?
- What is the best window of time for ice creation in order for the ice to then be covered in snow?

- Ice needs to be 1.91-2.46 m thick (Beaufort Sea) or 0.73-1.27 m thick (Transpolar Drift) to survive melting (van Dijke 2022). Can thickening of new ice to these thicknesses be achieved?
- Over what time period does water need to be pumped? What can be achieved in concentrated time of pumping vs less pumping spread out over more time?
- What type of pumping apparatus is feasible from a technical standpoint and from a logistical standpoint?
- How can water to thicken ice be effectively distributed across a large area?
- Is the addition of snow needed at the end of operations? What is the best way to accomplish this, if necessary, from a technical standpoint?

- 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)?
