The study analyzes the EDML ice core to understand how air bubbles transition into clathrates under hydrostatic pressure. By using digital image processing and pseudocolor transformations, the researchers identified distinct zones of ice: a bubble-only region (80–700 m), a transition region (700–1250 m), and a clathrate-only region (1250–2774 m). The findings demonstrate that 'cloudy bands' (CB), associated with higher atmospheric dust concentrations from summer precipitation, exhibit greater porosity variations and a faster transition to clathrates than 'clear ice' (CI) from winter precipitation. In the deepest sections, 'white dots' (clathrate aggregates) maintain a spatial distribution and concentration proportional to the original bubbles, confirming a continuity in the evolution of the ice structure.
