From: The open-ocean missing backscattering is in the structural complexity of particles

The backscattering coefficient is underestimated in the mesopelagic zone. Each bar indicates the average ratio between modelled optical backscattering coefficient at 532 nm derived from the selected coated-sphere parameterisations to that measured for a given sample in the mesopelagic zone, as collected along the AMT26 transect. Error bars represent the combined uncertainty (95% confidence intervals) as propagated from particle size distribution measurements (see Methods). Dashed line indicates the 1:1 ratio
