Abstract Subtropical gyres cover 26%–29% of the world's surface ocean and are
conventionally regarded as ocean deserts due to their permanent stratification, depleted …

The transfer of photosynthetically produced organic carbon from surface to mesopelagic
waters draws carbon dioxide from the atmosphere. However, current observation-based …

Export of sinking particles from the surface ocean is critical for carbon sequestration and to
provide energy to the deep biosphere. The magnitude and spatial patterns of this export …

A key uncertainty for predicting future ocean oxygen levels is the response and feedback of
organic matter respiration demand. One poorly constrained component of the respiration …

The importance of dissolved Fe (dFe) in regulating ocean primary production and the carbon
cycle is well established. However, the large-scale distribution and temporal dynamics of …

Multiyear estimates of organic matter (OM) export based primarily on oxygen and dissolved
inorganic carbon surface layer budgets applied basin‐wide for the Pacific, Atlantic, and S …

Abstract The subpolar North Atlantic plays an outsized role in the atmosphere‐to‐ocean
carbon sink. The central Irminger Sea is home to well‐documented deep winter convection …

One mechanism by which the ocean uptakes carbon dioxide is through the biological
carbon fixation and its subsequent transport to the deep ocean, a process known as the …

The magnitude and distribution of the ocean's biological pump (the downward flux of organic
carbon (OC) from the ocean surface) influences the pCO2 of the atmosphere and the O2 …

Abstract Model uncertainty in simulating the biological carbon pump was quantified and
partitioned using 14 models from the Coupled Model Intercomparison Project Phase 6 …
