A technical blueprint style infographic poster in 16:9 horizontal format showing a vertical cross-section of the ocean from surface waters down to the abyssal plains, designed to look like an engineering drawing for a deep-sea research project; the background is a dark navy blueprint grid with thin white construction lines and depth markings in meters along the side, no gradients, no textures beyond the grid; the composition is divided into labeled zones — EPipelagic, MESOpelagic, BATHYpelagic, ABYSSOpelagic and HADAL trenches — each separated by clean horizontal rule lines with bold uppercase technical labels; within each zone, white line-art illustrations show simplified outlines of characteristic creatures such as whales near the surface, lanternfish in the twilight zone, giant squid and anglerfish in deeper layers, and sea cucumbers and tube worms on the seafloor, all drawn as thin blueprint diagrams with small annotation arrows and codenames; include depth callouts at 200 m, 1000 m, 4000 m, and 11000 m with clear numeric labels; in the upper left, place a bold title block reading BATHYAL ZONE – ANATOMY OF THE DEEP SEA in a condensed technical sans-serif; add a legend box explaining icon types (fish, invertebrates, human vehicles, etc.) and a tiny schematic of a research submersible for scale; use only white and one accent color (cyan) for key highlights and zone dividers, keeping the overall aesthetic crisp, precise and engineering-focused, high quality, 16:9 horizontal ratio.
