Halocline

A schematic water-column graphic showing stratified water with lighter low-salinity water above and darker high-salinity water below, separated by a narrow horizontal salinity transition layer. The halocline appears as a thin, distinct band with a strong vertical color gradient from pale blue or blue-green at the top to darker blue beneath, emphasizing rapid salinity change over a short depth interval. The surrounding water column may be shown as a vertical rectangular panel or slim profile block, with smooth parallel boundaries and optionally subtle layered or contour-like stripes; the transition band can be flat, gently wavy, or slightly sloping but remains visually sharp and clearly defined.
