Editor’s summarySinking marine particulate organic matter, commonly called “marine snow,” moves huge amounts of carbon from the new-surface ocean to depth, constituting one of the major components of Earth’s carbon cycle. The biological and physical complexity of these particles, together with the wide range of lengths and timescales that are involved in their motion, have made it exceedingly difficult to determine their dynamics in detail.

AbstractThe daily vertical migrations of plankton play a crucial role in shaping marine ecosystems and influencing global biogeochemical cycles. They also form the foundation of the largest daily biomass movement on Earth. Surprisingly, amongst this diverse group of organisms, some single cell protists transit these depths exceeding 50 meters without employing flagella or cilia, and the underlying mechanisms remain poorly understood.
