Abstract
Abstract The particulate organic carbon (POC) flux from the euphotic zone to the deep ocean is central to the biological carbon pump. It is typically evaluated using “export efficiency” and “transfer efficiency,” which reflect POC formation and sinking and carbon sequestration efficiency in the ocean's interior, respectively. Since observations of these metrics are limited, biogeochemical models can elucidate the controls of large‐scale patterns. This study uses the global ocean‐biogeochemical model FESOM‐REcoM, with a new sinking routine that accounts for ballast minerals, seawater viscosity,
