The diel vertical migration
- "Every night, under the cover of darkness, countless small sea creatures swim from the ocean depths to feed near the surface, then descend out of sight again before daybreak. This vast animal migration—a critical part of Earth’s carbon cycle—has been observed for the first time on a global scale thanks to a space-based laser." - Excerpt from NASA Earth Observatory
