Quantifying the Carbon Export and Sequestration Pathways of the Ocean's Biological Carbon Pump
Global Biogeochemical Cycles, 2022 The ocean's biological carbon pump transfers carbon from the surface ocean to the deep ocean by several distinct pathways, including gravitational settling of organic particles, mixing and advection of suspended organic carbon, and active transport by ...

Quantifying the Ocean's Biological Pump and Its Carbon Cycle Impacts on Global Scales.
Annual Review of Marine Science, 2022 The biological pump transports organic matter, created by phytoplankton productivity in the well-lit surface ocean, to the ocean's dark interior, where it is consumed by animals and heterotrophic microbes and remineralized back to inorganic forms.
