APERO - Carbon sequestration in the ocean
APERO aims to reduce the gap between the amount of organic carbon produced by photosynthesis that sinks out of the surface and the demand for biological carbon deep in the water column.
APERO's three main original contributions are the study of the role of sub-measured circulation (~1-10km) using autonomous profilers and new optical instruments, the function of genes linked to carbon export and the implementation of innovative models concerning biogeochemical fluxes and molecular ecology.
Based on intense international collaboration and an ambitious observation strategy, the in situ study (the objective of this ANR project) is scheduled for 2020 (NE Atlantic: 40 days of cruising with 2 ships). APERO will reduce the uncertainties surrounding our ability to model carbon sequestration in the ocean.
The 2023 oceanographic campaign
A campaign took place from 2 June at 15 July 2023 during the summer bloom in the north-east Atlantic, at the time of maximum particulate carbon export to the deep ocean.
