Unrealistic sinking speeds for particulate matter. #8
Description
There is a potential issue in the definition of particulate tracers.
Line 603 of the original code is: is_solid(26:28) = 1, which hardcodes some of the tracers defining them as solids, which could cause problems when the configuration of biogeochemical modules changes slightly or if other modules (e.g. Oxydep) are used.
