Embodiments generally relate to methods and apparatuses for generating ice. In one embodiment, at a generation location, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms; then at a target location, the formed ice is deployed on a top surface of a body of water, or of a pre-existing body of ice, or of ground. The formed ice has an albedo greater than or equal to 0.15. The formed ice contains light scattering centers created by the introduced material. The material comprises hollow particles.
