[Back on #Earth ...] Between land and sea there's the beach, the #sand and its grains of #quartz that the breaking #waves continuously disintegrate, feeding the #phytoplankton with dissolved silicon.

This new source of dissolved silicon has just been discovered by several OMP researchers, including Sébastien Fabre from IRAP. It joins those provided by rivers, groundwater discharges and hydrothermal vents.

How is the #BiologicalPump, the mechanism by which the ocean captures and sequesters atmospheric #CO2, affected? Find out here: https://www.irap.omp.eu/en/2025/03/the-contribution-of-sandy-beaches-to-the-oceanic-silica-cycle/

Secrets to Southern Ocean's critical role in slowing climate change revealed

A new paper provides insights on one of the most important factors in the Southern Oceanic carbon cycle, the "biological pump," where carbon is utilized by organisms at the surface and transferred to ocean depths, away from contact with the atmosphere. The study, authored by scientists from NOAA's Pacific Marine Environmental Laboratory and the University of Hawaiʻi at Mānoa, was published in PNAS.
