Biological carbon pump & its sensitivity to climate change

Aim of the project is to examine the influence of changing environmental drivers (temperature, pH, oxygen) on vertical carbon fluxes and flux attenuation (as a measure of biological pump efficiency) using a global image-based dataset of particle fluxes from the Underwater Vision Profiler 5.
Global dataset of UVP5: > 8000 vertical profiles of particle size distribution from the sea surface down to a maximum of 6000m depth
Calculation of carbon flux based on particle size distributions
Vertically resolved flux data allows to compute attenuation of carbon flux with depth (”Martin’s b” or other measures, such as remineralization length scale, transfer efficiency…)
