SPF ICE: A Novel Approach to Predict the Optimal Amount of Silica to Preserve Glaciers Using Reinforcement Learning
<div><div><div><p>Glaciers cover nearly 10 percent of the earth’s surface but are melting at an inexorable rate. According to the pacific standard magazine, the Arctic sea ice has lost 80 percent of its volume since 1979. Antarctica’s ’Doomsday Glacier’ is melting faster and could raise global sea levels by two feet. As three-quarters of the earth’s freshwater is stored in glaciers, its melting depletes freshwater resources for millions of people. Glaciers also play a huge role in the climate crisis. Preserving glaciers is an important and imminent solution to save our planet. Silica microspheres are promising materials to prevent glacier melting as it reflects most of the sun’s radiation. When spread in layers over the glacier, it can slow the rate of melt and aid in new ice formation. However, if not used precisely, silica can be ineffective and expensive. SPF ICE is a novel method implemented to effectively de- termine the optimal amount of silica based on glacier’s properties to prevent its depletion substantially using reinforcement learning agents and a custom OpenAI Gym environment. The environment simulates a real-world model of a glacial setting using specific data, such as the glacier’s mass balance, tem- perature, and average accumulation and ablation. After testing the agents during many episodes, my solution reduced glacial melting by an average of 60.40% using the optimal amount of Silica. Additionally, this solution is customizable for any type of glacier. SPF ICE is an efficient and low-cost solution to curb glacier melting to preserve planet earth.</p></div></div></div>
