Schematic representation nutrient and carbon flows
About this model
A schematic representation of nutrient and carbon flows in the biogeochemical model ERSEM-BFM, including DOM (Dissolved Organic Matter), POM (Particulate Organic Matter) and DIC (Dissolved Inorganic Carbon). TA stands for Total Alkalinity. The fish symbol indicates mortality due to fish predation, which is included in the model as cannibalism to ensure a biomass-based response (more prey biomass means increased predation). The sea bed consists of 3 layers: the oxic layer, the denitrification layer and the anoxic layer, which are separated by the oxygen penetration depth and the sulfide horizon depth, respectively.
