Enhanced transfer of organic matter to higher trophic levels caused by ocean acidification and its implications for export production: A mass balance approach

KOSMOS mesocosm unit and conceptual figure of element pools and fluxes.
(A) Schematic illustration of a KOSMOS unit, including the floatation frame at the sea surface and the enclosure bag reaching down to the sediment trap at the bottom. (B) Element pools (inorganic nutrients [IN], dissolved organic matter [DOM], particulate matter [PM], particulate matter of copepods [PMCOP]) and fluxes (air-sea gas exchange of CO2, sedimentation of particulate matter [PMSED]) included in the mass balance calculations of carbon, nitrogen, phosphorus, and silica (C, N, P, and Si). Grey arrows indicate exchange between the individual element pools in the water column. Illustration of the KOSMOS unit modified from Rita Erven (GEOMAR).
