New Study Uncovers Surprising Physics of 'Marine Snow'

New study uncovers surprising physics of 'marine snow'

The deep ocean can often look like a real-life snow globe. As organic particles from plant and animal matter on the surface sink downward, they combine with dust and other material to create "marine snow," a beautiful display of ocean weather that plays a crucial role in cycling carbon and other nutrients through the world's oceans.

Gravity, flipped: How tiny, porous particles sink faster in ocean snowstorms

In a twist on conventional wisdom, researchers have discovered that in ocean-like fluids with changing density, tiny porous particles can sink faster than larger ones, thanks to how they absorb salt. Using clever lab experiments with 3D-printed agar shapes in a stratified water column, scientists demonstrated that porosity and particle shape are major factors in determining sinking speed. This finding could revolutionize how we understand carbon…
