Figure 5From: Modelling potential impacts of bottom trawl fisheries on soft sediment biogeochemistry in the North Sea†Model simulation results showing steady state total benthic CO2 production and the proportion of that production due to direct aerobic processes as a function of physical mixing (PMM) hypothetically caused by trawling activity. Macrofauna are kept at a level of about 70 mmol (C) m-2 for all simulations. At PMM levels greater than 15, the model has multiple solutions.Back to article page
