海洋深度分层图

一张竖版长信息图，从海面到海沟可视化五个海洋深度带。背景由顶部淡水绿渐变到底部近黑，分五条横向色带，与各深度带配色一致。左边纵向刻度尺自 0 至 11000 m，关键参考深度：「Scuba record 332 m」、「Wreck of the Titanic 3800 m」、「Average ocean floor 3700 m」、「Mariana Trench 10984 m」。右侧标深度带 「Sunlight 0-200 m」、「Twilight 200-1000 m」、「Midnight 1000-4000 m」、「Abyss 4000-6000 m」、「Hadal 6000-11000 m」。每条带中两幅小水粉生物剪影漂浮于正确深度，斜体标 「dolphin」、「giant squid」、「anglerfish」、「sea pig」、「How Deep Does It Go?」。一艘潜水器剪影在 4000 m，细线连至海面。顶部标题 「How Deep Does It Go?」。页脚 「海洋深度分层图」。柔和笔触，细网格，留白充足。

A tall portrait infographic visualizing the five ocean depth zones from surface to trench. Background fades from pale aqua at the top to near-black at the bottom in five distinct horizontal bands, each one matching a zone color. A meter scale runs along the left edge from 0 to 11000 m, with key reference depths marked: "Scuba record 332 m", "Wreck of the Titanic 3800 m", "Average ocean floor 3700 m", "Mariana Trench 10984 m". Zone labels in clean sans-serif sit at the right edge: "Sunlight 0-200 m", "Twilight 200-1000 m", "Midnight 1000-4000 m", "Abyss 4000-6000 m", "Hadal 6000-11000 m". Inside each band, two small gouache silhouettes of representative organisms float at correct depths, labelled in italic, e.g. "dolphin", "giant squid", "anglerfish", "sea pig", "snailfish". A submersible silhouette sits at 4000 m with a hairline trace line up to the surface. Title across the top reads "How Deep Does It Go?". Small footer credits "Depths in meters, illustrative". Soft brush textures, hairline grids, generous vertical breathing room.
