Deep Pressure Squeezes Food From Marine Snow
Laboratory pressure tanks made sinking particles leak up to half their carbon and roughly 60 percent of their nitrogen.
Summary
Laboratory pressure tanks made sinking particles leak up to half their carbon and roughly 60 percent of their nitrogen.
University of Southern Denmark experiments found hydrostatic pressure forced proteins and carbohydrates from simulated marine snow, driving a 30-fold rise in bacteria within two days. The leakage may keep more carbon in deep water instead of sediment. An Arctic expedition will test whether the pressure-tank mechanism leaves the predicted fingerprints in nature.
Why it matters
Laboratory pressure tanks made sinking particles leak up to half their carbon and roughly 60 percent of their nitrogen.
Limits and context
No additional limitation was separately recorded.
