Biogenic silica fluxes in the seasonally ice-covered Northwind Ridge, western Arctic Ocean: drivers and implications for the biological carbon pump.

The silica cycle is intimately coupled with marine food-web dynamics, biogeochemical transformations, and the efficiency of the biological carbon pump (BCP). To elucidate the factors controlling biogenic silica (bSiO2) flux and its role in carbon export, we conducted a year-long (August 2008-September 2009) sediment tr...

Cyanobacteria Sustain Deep Ocean Carbon Sequestration Despite Eukaryotic Loss

The biological carbon pump exports phytoplankton‐derived organic carbon to the deep ocean, regulating long‐term carbon sequestration and climate. Yet how phytoplankton community composition controls the magnitude and efficiency of this process remains poorly understood. Using time‐series sediment trap samples, we analy...
