Measurements of sea ice thickness and its subice morphology analysis using ice- penetration radar in the Arctic Ocean
Based on radar penetrating measurements and analysis of sea ice in the Arctic Ocean, The potential of radar wave to measure sea ice thickness and map the morphology of the underside of sea ice is investigated. The results indicate that the radar wave can penetrate Arctic summer sea ice of over 6 met...
