This project focuses on enhancing understanding and prediction of sea ICE patterns in hotham inlet (A.K.A. Kobuk lake), alaska, which is crucial for the kotzebue sound communities reliant on sea ICE for transportation and hunting. Central to our initiative is subzero, a novel model adept at simulating the breakup of sea ICE, a key process in confined areas like kobuk lake. This lakes ICE breakup, driven by wind rather than complex ocean currents, presents a unique opportunity for subzero to accurately replicate ICE floe dynamics. We aim to apply subzero in studying kobuk lakes seasonal ICE breakup, a pivotal spring event with significant implications for local residents. To improve our model, we will utilize a combination of high-resolution lidar-based measurements from the arctic air programs aerial surveys and satellite data for sea ICE thickness. Collaborating with local scientists, we will integrate their in-situ measurements and indigenous knowledge to refine and validate our sea ICE model. Presently in its developmental phase, this project seeks to advance subzero from an early stage (readiness level 3 or RL3) to a more sophisticated level (RL6), providing scientific insights and tangible benefits for the kotzebue sound communities through improved sea ICE prediction tools.
