This resource provides an abstract. This study investigates tsunami shadows, extended dark strips on the ocean surface before a tsunami. Such shadows are found to result from an air-sea interaction induced by tsunami-related atmospheric disturbances. Results suggest that remote surface water observations can be used to detect deep ocean tsunamis via their shadows and thus provide significantly more reliable and earlier warning before the large waves strike vulnerable shores.
