海洋B卷背景：泰国斯内尔窗口效应

t refracts through the ocean surface in a Snell's window effect, the optical phenomenon that defines how light and life interact in the upper Andaman Sea. This narrow cone of visibility is also the zone most exposed to sea surface temperature rise, the same warming process that drives coral bleaching events on reefs below. Clean, uncluttered blue water like this is widely used as nature b-roll and transition footage in ocean and climate storytelling. 4K, horizontal, wide angle, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
